CDDA Version 1.7 (build 0x0189) - This is the twelfth release of CDDA. Homepage: http://www.ncf.carleton.ca/~aa571/index.html CDDA - What is it? ------------------ CDDA is a DOS PC based utility that allows the user to extract digitally perfect copies of samples from audio CDs. It also allows the user to extract MPEG streams from CDi Digital Video CDs, XA frames from CD-XA CDs, and CD+G data from audio CDs. It now supports SCSI drives through the ASPI drivers, ATAPI drives through the ASPI drivers in Windows 95, ATAPI drivers through the ATASPI drivers, and most other drives through the MSCDEX interface. **** NOTE **** Release 1.0h was the last free release of CDDA. Since then I have made some drastic changes to the program to include XA and most importantly CDi. It is because of the fact that Phillips in their infinite wisdom want to "license" their CDi technology, that I must now turn CDDA into shareware. I am not happy about having to shell out several hundred dollars to get ahold of their "GREEN" and "WHITE" books. The new registration fee is small, and I don't intend to screw the user with paying a more than $100US fee before knowing if it may or may not work for them. Starting with version 1.6 all new features and bug fixes will only be available to REGISTERED USERS. The unregistered version will still work for extracting DA, but other data modes are in the registered version only. When you register I will email you a key file that will allow you to use all the wonderful new features. It will also get you a registration number that you can use when you email me for support. Hint: expect much better support when you are a registered user. I have received thousands of requests for support, and I just don't have time to give each person a lot of help if they don't register. The following is a list of all the new features that have been added to version 1.6. Only registered users will be able to use them. The only exceptions to this are the /ATASPI and the /95ATAPI modes. ------------------------------------------------------------------- * /MINLBA <override value of the first frame (LBA) of the CD> * /MAXLBA <override the frames (LBA) from the end of the CD> * /TM <stop MM:SS:FF from end of track> * /TP <start MM:SS:FF from start of track> * /RESET - reset the drive before extracting data * /SPEED <speed at which to extract data 1, 2, 4 times etc.> * /CHANNEL <audio channel (STEREO, LEFT, RIGHT, MONO)> * /FORMAT <CDDA file format (WAV, AIF, VOC, BIN, HEX)> * /SAMPLE <audio sample size in KHz (44, 22, 11)> * /MODE <data mode> CDDA - read raw CD-DA frames XA - read raw CD-XA frames CDG - read raw CD+G data 2048F1, 2056F1, 2324F2, 2332F2 - x form y frames) CDIVIDEO - read plain MPEG video from a CDi disc CDIAUDIO - read plain MPEG audio from a CDi disc CDIRAW - read raw MPEG video/audio from a CDi disc * /LRSWAP - swap the left and right audio channels * /LMSWAP - swap the LSB/MSB of the audio channels * /ADLC <scale factor for Automatic Digital Level Control> * /DL - display average digital level /ATASPI - force CDDA to use ATASPI device driver /95ATAPI - force CDDA to use ATAPI drive under Windows 95 As well, the average data extraction speed, and average DA jitter will be displayed at the end of the registered program. These may end up being very useful tools to help identify which drives do the best job at extracting DA. ------------------------------------------------------------------- I know I've said it before, but this could be the last release of CDDA. As far as I can tell, it seems to work fairly well on most machines now. Unless there is a life threatening bug found, I can't expect to have the time to put into this program for a while. The amount of email I get now is getting to be a problem. If you want help make sure you send me all the info about it, if you expect me to respond quickly. I don't give high priority to messages like - "Please help. I can't get your program to work." If you don't tell me a LOT more than this, don't expect much in the way of help. PS: I have been getting a lot of mail from people who are having trouble running CDDA. It turns out most of them are running it in a DOS box under Windows. This is usually a bad thing. I have added a check to see if either disk caching or Windows is running, and if so will warn you of the potential problems. Again I really don't expect to have a version that will run reliably under Windows any time soon. CDDA has been running very well for the last few months, and it would appear that it is stable enough not to need any more updates. I just don't have any more things I can fix. Some History ------------ In February 1993, I needed to get some audio samples into digital form on my PC. Toshiba had just released the 3401 CDROM drive which allowed reading of DA frames across the SCSI bus. Because there were no programs available to do this, I had to write my own. I used it to get the samples, and then left it alone because I had no idea anyone else wanted to do this. Some months later CDGRAB came out, but they wanted much too much money for their program, so I cleaned up the program and released it as CDDA09A.ZIP. Note: Some time later I heard from a very irate person who told me I couldn't use the name CDDAxxx.zip because he was already using the name. I've looked everywhere, used ARCHIE, and asked people who seem to know every program on the net, and no one has seen this guy's program. However, in the interest of keeping peace on the net, I have changed the distribution file name to DA2WAV1G.ZIP. The program itself will still be called CDDA. NB: I finally found this elusive CDDA. It turns out to be a CD Duplicate Analyzer to search for duplicate files on two different CDROMs. The first release fully supported the Toshiba 3401 CD-ROM drive. I have since added a whole bunch more including MSCDEX only. I have given prerelease versions of my program to people who have to some degree had success with other drives. I have no guarantees that this program will work with your drive. Since the release of 1.0a I have heard from people who were having trouble with the NEC 74-1/84-1 drives. So, I went out and borrowed one for a few days. To my surprise the 84-1 didn't work. The next thing I did was get the data sheets for the drive sent to me from the NEC faxback. There is no mention of being able to read DA frames on that data sheet. Next, I reread the NEC programming manual. It says about the 74-1/84-1 drives "Read CD-DA is under consideration of content in the SCSI support commnds". This suggests that it may or may not be supported. Next I called NEC tech support. They told me that "reading digital audio through the SCSI port is NOT supported on the 74-1/84-1 drives. It is supported on the 3x and 4x drives." So, for the time being, I will leave in the code to support the 74-1/84-1 drives. If I don't hear from someone who gets it to work in the next while, I will remove the support and mention it in this file. I have also heard from someone who has a NEC 211 drive. I have no idea what this drive is other than it is a 2X drive. This person has had good success running CDDA. I have also heard from someone with NEC 210 who has not had success. If anyone knows more about programming for NEC drives please let me know. To add to the NEC confusion, NEC tech support is still telling people that the 74-1 and 84-1 drives CAN read DA frames. This is just not true. If NEC can't get their own tech support staff trained, can you imagine the quality of their drives? I wanted to be sure that I had full support for all the NEC drives, so I called tech support again. This time I had to wait on hold for over an hour to talk to a tech droid tell me that he didn't know the answer, but would call me back later in the day with an answer. That was six+ months ago and I haven't heard from him. Next, I tried the email tech support for NEC. I got an email back saying that they would look into it and get back to me right away. I have sent follow up emails, and again I haven't heard from them in over six months. I am not going to try any more NEC support. Period. If they can't get their act together to support their users/developers, then everyone should buy drives from another vendor. With all the trouble over the OEM'd 3x drive, I would think that no one would ever buy a NEC drive again. BTW, has anyone heard of a NEC drive since the final version of the 74/84 that actually works correctly? I know I haven't, and that includes all the new 4x and IDE drives. I you know otherwise let me know. In the mean time I might suggest another vendor. There has been a lot of talk about the Mitsumi drives and whether they will work with CDDA and like programs. The bottom line is this: I talked to an engineer in the CDROM group at Mitsumi, and he told me that none of their drives will read DA frames, and that none of their drives ever will. It appears that Mitsumi is concerned about the copyright issues of CDDA. I know we have all heard rumours about people getting the drives to work, but I trust the word of the head s/w designer for CDROM drives over a fourth hand rumour. If your drive has a part number like FX001D or FX400, then you have a Mitsumi drive and you won't get DA from your drive. The reason I have left the Mitsumi in the program is that the Mitsumi drives WILL read XA/CDi frames. For that reason, you can extract your MPEG movies, but you can't extract DA. Different ROM revisions cause the drives to do things differently. One version may work just fine and others might not. It is very tough for me to help with drives that don't work, when I don't have one of those drives to work with. If your drive revision is on the bad list, I don't know what to tell you. Perhaps you can make a really big stink with the manufacturer and have them upgrade your rom. Here is a list of known good and bad rom revisions. I will add to this list as I receive reports from the field. Hint: that means if you get this program working, please, please, please send me dumps of the output, so I can update these docs. You will notice no changes to this list since the last version of CDDA. This is because I haven't received any dumps from people that have the program working. good bad ---- --- Sony 561 rev 1.9a Sony 561 rev 1.7x Sony 561 rev 1.8p Sony 561 rev 1.8f Sony 8012 rev 3.1e Sony 55s 1.0q Toshiba rev 0283 Toshiba rev 2732 Toshiba rev 3593 NEC 211 rev 1.0 NEC 84-1 rev 1.0 NEC 210 (note: I'm giving up on this list because so few people report back with decent descriptions about what works and what doesn't. Don't expect any new additions to this list.) What drives support DA? ----------------------- I have heard from many different people who say such-and-such drive will read DA frames. The following is a list of which drives which I understand have the ability to read DA frames, and that I have included support in CDDA: (thanks to bwilliam@iat.holonet.net for starting this list). Note: My including suport for a drive does not mean that it is guaranteed to work on your machine. It means that I have either heard from someone who has managed to get it to work or I have the programming manual for the drive and have included the code to support it. Certainly don't go out and buy a specific drive on this list just because I said CDDA might work. Be sure to try the drive before you buy. As I said above, I get so little feedback from people who actually get CDDA running that I can't update this list. Don't expect any more updates. Apple 300, 300i, 300e (Sony CDU-8003, CDU-8003A, CDU-8012) Apple CD300+ Chinon CDS-535 COMPAQ CR503/CDU561 DEC RRD42 Goldstar GCDR-540 IDE HP 4020 Nakamichi MBR7 NEC CDR 200, 300, 400, 500, 600, 900 series NEC CDR 84-1/74-1 (rumoured with special firmware) (NEC told me that it didn't exist) Panasonic CR-562B/563B/572/574/581 Pinnacle RCD1000/5030 Pioneer 124/624 Plextor 4Plex/6Plex Sanyo C3G IDE Sony CDU-561, CDU-31A, CDU-33A, CDU-55S, CDU-55E, 76E/76S Toshiba XM3301 (Silicon Graphics) Toshiba XM3401, XM4101, (XM3501 with 0925 and later firmware), 3601, 5302 Hitachi Matshita (Panasonic) 503 Yamaha CDR100/102 Kodak PCD225,6x/Philips CDD522/Plasmon RF4100/JVC XRW2001 The code to support the Pinnacle drives is included in CDDA. However, as of this writing, there is a problem with some of the RCD1000 drives that prevents CDDA from running. I have heard from tech support that they might have a ROM revision that will fix the problem. If you have one of these drives I suggest that you call Pinnacle and scream at them for the fix. The newer 5020 and 5040 drives should work fine with CDDA. There are a whole slew of new drives coming out with the ATAPI. A lot of rumours are floating around as to whether they will work or not. Toshiba especially is coming out with a new drive every other week it seems. Until I can get more detailed results, I will not enter them in the supported drive list. You may want to run CDROMINF.EXE and have a look at the output. If there no mention of being able to read RAW frames, and/or the RAW READ SIZE is not 2352, there is no chance that CDDA will work using the MSCDEX interface. Also, if it reports that your drive supports reading RAW, that DOES NOT mean that CDDA will work. It all depends upon the person who wrote the driver for your drive. If he/she passes DA frames to MSCDEX, you're laughing. Otherwise, you're out of luck. Starting with verion 1.6 of CDDA, CDROMINF is no longer distributed with CDDA. It is now a separate program available from Simtel in msdos/cdrom/cdinf11.zip. There are also pointers to the most recent version of CDROMINF on my homepage: http://www.ncf.carleton.ca/~aa571 If you have an ATAPI drive then you might also want to run another program of mine called ATAINF. It will display a lot of information about your drive and will tell you if it can read digital audio. The file is available from Simtel in msdos/cdrom/atainf11.zip. There are also pointers to the most recent version of ATAINF on my homepage: http://www.ncf.carleton.ca/~aa571 There are rumors that the Mitsumi LU055 drive will work using the MSCDEX interface, but I have yet to hear specifically what version drive, and what version driver works. NO OTHER Mitsumi drives are supported. It is not my fault, it is Mitsumi's fault. Complain to them not me. If you know or think you know of other drives, let me know and I will do some investigating. What is this CDi support? ------------------------- Phillips has developed a standard for storing about an hour of video and audio on a standard CD. The data is really a long MPEG I stream. CDDA will allow you to extract either the raw MPEG stream, or just the video stream. You can then play back the movies with any of the standard MPEG file players. Have a look at the included file CDIFAQ.TXT. This gives a very basic run down of what CDi is all about. Phillips has two disc standards: WHITE book and GREEN book. Green book was the first standard, but was really only any use if you were using a real CDi player. It has a proprietary file system and most CDROM players won't accept the discs. Phillips finally smartened up and decided that they wanted to expand their market so they came up with the White book standard. The only difference is that these new discs come with the file system built around ISO 9660. This way most every CDROM drive in the world will allow you to look at the directory structure. To get at the movie data you still need a drive that supports CDi. Fortunately, as far as my program is concerned, if your drive supports XA and you have a White book disc, then you are probably ok. When you have a White book CD installed, CDDA detects this and will attempt to display a list of MPEG streams contained on the disc. They should be displayed as file names from the CD in the form of /MPEGAV/*.DAT. It should also give you an idea of the starting block of the stream if you want to use the /LBA option. Have a look at the included file CDCOMPAT.TXT. It is a list from Sigma Designs (the people who make the RealMagic MPEG card) as to what CD-ROM drives work with CDi movies and what don't. Have a look at this list before yelling at me because your drive doesn't work. What about CD+G? ---------------- CD+G is a standard way of encoding pictures and lyrics in the unused bits of the audio data stream on plain audio CDs. Very few CDs have this data, but for those that do, it is kind of neat to see in action. As of version 1.6, CDDA allows you to extract the raw CD+G data which is really contained in the R-W subcodes. You can then use my CDGPLAY program to play the data, or use CDGPLAY to play directly from the CD. Have a look at my home page for pointers to the most recent versions of CDGPLAY. How do I use this program? -------------------------- This is a command line utility which allows the user to specify the start and end points of the data transfer and the output type. The start and end points may be entered in one of three modes,: LBA, MSF and T (track). Make sure that you don't use more than one of these modes in the command line because it really confuses the parser in CDDA. Logical Block Address mode is the number of the frame from the start of the disc. Minute, Second, Frame mode specifies the time from the start of the disc in actual time. Track mode allows you to dump an entire track (or song) to disk. The LBA and MSF are related by the following formula: LBA = Minutes * 60 * 75 + Seconds * 75 + Frames - 150 The lead in track is usually 150 because there are usually 2 empty seconds at the start of a CD, but it can also be any number +- 75 frames from 150. A commmon number other than 150 is often 182 or 183. The Toshiba, NEC and MSCDEX programming manuals define the LBA equation to be as above with -150 at the end. The Sony manual is very vague, and it could be interpreted as either -150 or as -(lead in track). Since two of the three manuals say clearly -150, I have chosen -150 for the Sony as well. I managed to do a fair bit of testing on a Sony 561 drive, and it appears that the -150 figure is correct. If anyone has more precise information on the Sony please pass it along. ------------------------------------------------------------------------- Usage:CDDA <range of audio mode><drive mode><data type mode> /F filename Modes marked with an * are available only in the registered version Modes to select range of audio to extract: /MSF, /LBA /T Defaults: none /MSF - times in minute, second, frame format (MM:SS:FF) /LBA - times in Logical Block Address format (xxxxxx) /T <track number> /S <start time for MSF and LBA mode> /E <end time for MSF and LBA mode> /BLOCK <number of blocks pulled from the drive at a time> /OVERLAP <number of overlap blocks used for jitter correction> * /MINLBA <override value of the first frame (LBA) of the CD> * /MAXLBA <override the frames (LBA) from the end of the CD> * /TM <stop MM:SS:FF from end of track> * /TP <start MM:SS:FF from start of track> Modes to select drive type and interface Defaults: ASPI, first found SCSI/MSCDEX drive /M - force CDDA to use MSCDEX only instead of ASPI /ATAPI <IO:DEVICE> - force CDDA to bypass ATAPI driver IO (hex) address of IDE controller DEVICE 0/1 for Master/Slave drive on IDE controller> /ATASPI - force CDDA to use ATASPI device driver /95ATAPI - force CDDA to use ATAPI drive under Windows 95 /MSC <drive letter of CDROM drive> /ID <scsi id of CDROM drive> /LUN <lun id of CDROM drive> /ADAPTER <ASPI scsi adapter number> * /RESET - reset the drive before extracting data * /SPEED <speed at which to extract data 1, 2, 4 times etc.> Modes to select output data format Defaults: STEREO, WAV, 44KHz CDDA * /CHANNEL <audio channel (STEREO, LEFT, RIGHT, MONO)> * /FORMAT <CDDA file format (WAV, AIF, VOC, BIN, HEX)> * /SAMPLE <audio sample size in KHz (44, 22, 11)> * /MODE <data mode> CDDA - read raw CD-DA frames CDXA - read raw CD-XA frames CDG - read raw CD+G frames 2048F1, 2056F1, 2324F2, 2332F2 - x form y frames) CDIVIDEO - read plain MPEG video from a CDi disc CDIAUDIO - read plain MPEG audio from a CDi disc CDIRAW - read raw MPEG video/audio from a CDi disc * /LRSWAP - swap the left and right audio channels * /LMSWAP - swap the LSB/MSB of the audio channels * /ADLC <scale factor for Automatic Digital Level Control> * /DL - display average digital level Misc. modes /P - Play audio CD sample range /U - estimated disk usage required for data /O - override copy protection bit /NJC - do not perform jitter correction on audio data Note: filename extensions will automagically be added to the filename e.g. CDDA /MSF /S 10:14:36 /E 13:55:11 /F outfile e.g. CDDA /LBA /S 106232 /E 109443 /F outfile /format bin e.g. CDDA /T 2 /F outfile /O /format aif -------------------------------------------------------------------------- The /ADAPTER option allows you to manually set the number of SCSI Adapter that has the CDROM drive you want to use. This is useful i if my software incorrectly guesses which adapter your drive is using, or if you have more than one adapter in your system. The /ID option allows you to manually set the SCSI ID of the CDROM drive you want to use. This is useful if my software incorrectly guesses your drive's ID, or if you have more than one CDROM drive in your system. The /LUN option allows you to manually set the SCSI LUN of the CDROM drive you want to use. This is useful if my software incorrectly guesses your drive's LUN, or if you have a multi-CD drive in your system like the 6 Pack from Pioneer. The /MSC option allows you to manually set the MSCDEX drive letter of the CDROM drive you want to use. This is useful if my software incorrectly guesses your drive's ID, or if you have more than one CDROM drive in your system. This option does not force the software into the /M (MSCDEX only) option. The /M option forces the software to use only MSCDEX commands. This may or may not work with your drive. If you don't have a SCSI CDROM drive with ASPI drivers, an ATAPI drive under Win95, or an ATAPI drive with ATASPI drivers, this is your only hope. This option would be used with the Panasonic CR-562/563, Sony CDU-31A/33A drives. The /ATAPI option is to bypass the device driver and MSCDEX for the DA specific portion of CDDA. This new code is very preliminary and will probably hang your ATAPI drive once and a while. I wrote this code to show that a drive can or cannot read DA, regardless of what the driver says. If you find that using the /M option does not work with your ATAPI drive, try using the /ATAPI. If it runs, even for a few frames, then your drive is not the problem when using /M, it is your device driver. It is at this point that you need to start screaming to your vendor about crappy software. If /ATAPI doesn't work, and you have looked at the output of ATAINF which says your drive doesn't support DA, then you are really out of luck. ATAPI is followed by two parameters the IO address of the controller card, and the device number. eg. /ATAPI 170:1 The IO address can be one of the following 1f0 170 1e8 168, and the device can be either 0 (master) or 1 (slave). You need to remember to use the /M option in addition to the /ATAPI option otherwise CDDA assumes that you are using a SCSI drive. The /NJC option forces the software to not do any jitter correction to the data read from the CD. This means that the program will run faster, but that the files created cannot be guaranteed to be 100% perfect copies. The /P option starts the CDROM drive playing the selected range of audio out either the headphone jack on the front or out the line level jack on the back. The /BLOCK option allows you to set the number of blocks to be read from the CD at a time. Before version 1.4a this was fixed at 10. You can set it as high as 56 (assuming no overlap) to increase the performance of CDDA by as much as 40%. This magic number of 56 is the same as 128K of memory which appears for many systems to be a magic number for the maximum number of frames you can read at a time. Associated with this option is the /OVERLAP option which allows you to specify the number of blocks overlap at the start and end of each read from the disc to be used in the jitter correction. Before version 1.4a the overlap was fixed at 3. Many of the newer drives can run with an overlap of 1 to give higher performance, and many of the old drives often need an overlap of 3 or higher. If you are getting jitter values which are always less than 275 then you should be able to use a jitter value of 1 or 2. If you are getting too large jitter errors, then you can try making the overlap larger than 3 to see if that fixes the problem. Remember that the memory buffer for reading frames is 56 blocks long. The formula for /BLOCK and /OVERLAP is (overlap*2)+block <= 56. You may have to play with the /BLOCK values to find ones that work optimally on your machine. When you are using CDi or XA modes the maximum value for /BLOCK has been fixed to 26, and the /OVERLAP values are always 0. Since there is no need for jitter correction with CDi and XA the extended block size for DA is not necessary. The magic number of 26 also applies to Windows 95. If you use anything more than that it tends to crash. Play with values larger than 26 under Win95 at your own risk. The /TM and /TP options can be used in conjunction with the /T command. The /TP command is used to start the extraction "Track Plus" amount of time after the start of the track. The /TM command is used to start the extraction "Track Minus" amount of time before the end of the track. For example /T 2 /TP 00:30:00 /TM 00:15:00 would extract track number two starting 30 seconds into the track and ending 15 seconds before the end of the track. The /MINLBA and /MAXLBA options are used to override the values returned by the drive for the Lead In Track and the Lead Out Track. This allows you to manually set the effective start and end of the CD. The /RESET command issues a SCSI reset to the CDROM drive before starting the extraction. The /SPEED command is used to select the extraction speed of the drive. For example /SPEED 4 would set the drive to 4X mode. The /MODE command is used to select the type of extraction from the CD. Default mode is CDDA. It can be any one of the following: CDDA - read raw CD-DA frames XA - read raw CD-XA frames CDG - read raw CD+G data CDIVIDEO - read plain MPEG video from a CDi disc CDIAUDIO - read plain MPEG audio from a CDi disc CDIRAW - read raw MPEG video/audio from a CDi disc 2048F1, 2056F1, 2324F2, 2332F2 - x form y frames, where x is the number of bytes per sector, and y is the frame type number The /FORMAT command is used to select the output file format of the audio data when using CDDA mode. You can select from AIF, WAV, VOC, RAW, and HEX formats. Default format is WAV. The /SAMPLE command is used to select the audio sample rate of the output file when using CDDA mode. You can select from 44, 22, or 11 which select 44.1KHz, 22.05KHz, or 11.025 KHz. Default sample rate is 44.1KHz. The /CHANNEL command is used to select the audio channel for the output file when using CDDA mode. You can select from LEFT, RIGHT, MONO, or STEREO. Default channel is STEREO. When you select LEFT, RIGHT or MONO, the output file will be only one channel instead of two. The /LMSWAP command is used to swap the least significant and most significant bytes of the audio data before saving to disk. The /LRSWAP command is used to swap the left and right channels of the audio data before saving to disk. The /DL command is used to enable the average digital level mode. At the end of a digital audio extraction, a 16 bit value will be displayed which is the average digital level of the extracted section of audio. You can use this command to find the average digital level of a track so that you can calculate the scaling factor when using the /ADLC command. The /ADLC command is used to electronically set the volume levels of audio data before saving to disk. The decimal number given following the /ADLC is used to scale the audio data as a percentage. For example, /ADLC 125 would raise the volume level of the audio data by 125%, and /ADLC 75 would effectively lower the volume level by mutiplying it by 75%. If you want to have the approximate same volume levels from audio tracks taken from different CDs, you have to make sure that the /DL command gives very close to the same numbers for every track. Your best bet is to take a single track from one CD and then make it your standard volume for your new CD. Then you will have to extract all the rest of the tracks using the /DL command to find the volume level for that track, then do the extract again using the /ADLC command and a multiplying factor based on the target volume level and the volume level before scaling. When running under a DOS window under Win95, some machines may support using ATAPI drives through the ASPI interface. However, bugs in Microsoft's drivers prevent this from working on some machines. I have worked a long time to get this working on a lot of machines, but I can't guarantee it will work on all machines. It has taken a significant amount of effort to get around many of the problems in the device drivers written by Microsoft. It appears to be worth the trouble so that you can have much more control over the drives. To use the ASPI interface to the ATAPI drives in a DOS window under Windows 95, you have to use the /95ATAPI option. As of version 1.6, you can also use CDDA with ATAPI drives through the ATASPI drivers. These drivers are for DOS and Win95 and usually come as part of "PowerIDE" from Future Domain when you buy their IDE controller. However, as far as I can tell, the drivers will work on any IDE controller, not just the ones from Future Domain. Using the ATASPI drivers is probably the best way to use CDDA and ATAPI drives. It means that I have the most control over the drive and can bypass all the normal device drivers. In this way I can be sure that the device drivers are not at fault when CDDA doesn't work. If you have a Future Domain IDE controller and PowerIDE, you are all set. You just have to add the device drivers in config.sys and autoexec.bat. (see below my example) If you don't have a Future Domain product, you will have to find the ATASPI drivers elsewhere. You might want to have a look at Mediavision's FTP site (ftp.mediavis.com), or their web site (www.mediavis.com), where they keep update driver files for many of their products. You might find update drivers for your MV600, which runs on a Future Domain controller. The two lines needed in my config.sys file are: device=c:\ataspi\ataspi16.sys /c:170,15,376h /v device=c:\ataspi\fdatacd.sys /d:mscd000 The line needed in my autoexec.bat file is: c:\ataspi\mscdex /d:mscd000 /v /e If you use the /ATASPI or /95ATAPI options, CDDA will also check to see if your drive supports reading DA or CD+G. No longer do you have to guess to see if the drive supports these modes, CDDA can now directly query the drive itself to see if it supports DA or CD+G. The CDIVIDEO, CDIAUDIO and CDIRAW options are to be used when you have a CDi movie disc. CDIVIDEO allows you to extract just the video portion of the MPEG stream. CDIAUDIO allows you to extract just the audio portion of the MPEG stream. CDIRAW allows you to extract the entire MPEG audio/video stream. If you use a program like VMPEG, or have a RealMagic card, then you will be able to play the movies from hard disk instead of from the CD. One thing to remember when using the CDi options: CDDA must hunt through the disc to find the start of the stream. A good way to figure out where the streams start is to look at the dump from CDROMINF. If you have a White book disc, then the streams start at the same point as the tracks 2 and up. Track 1 is for the file system and support files, and tracks 2 and up are for the MPEG. If you have a Green book disc, then you will have to choose a start point which is early enough in the disc to find the stream start. Often the streams start around LBA 3400. There may be more than one stream on a Green book disc. If you are using a White book disc, your best bet is to use the /T option, if you have enough disc space. When you want to play the MPEG files that you have extracted, your best be is to use a program like VMPEG. The latest version now also plays the audio. Remember that you are going to need a lot of computing muscle to do the MPEG decoding. Have a look at the following news post about CDi.

You may see messages during the dump about unknown subheaders. This is fairly normal. If you do get these messages, dump them to disk and send them to me. I will include checking in a later version of the program. There is a very long list of subheaders, and I have only added the ones I have seen in the 3 CDi discs I have. For the options /S /E /F which expect a following parameter, remember that there needs to be a space between the letter and the parameter. ie if you enter /S01:10:10, it would come up as an error, but if you entered /S 01:10:10, it would be correct. For the MSF mode, there need to be 2 digits for each of minutes, seconds and frames or it will come up as an error. When entering the filename with the /F, don't include an extension, as the software automagically adds the extension for you. At there are several file formats supported. WAVE (.WAV) and Binary (.CDA) are the types for DA, .XA for XA, and MPG for raw CDi and MPV for MPEG video. There is also the option to dump the data in HEX format out to the STDOUT device. The binary format has the audio samples stored in the order Left LSB, Left MSB, Right LSB, Right MSB. The samples are 16 bit 44.1 KHz stereo. On every CD there is a bit which defines if copying a particular track is permitted or prohibited. CDDA checks this bit and will not continue with the dump to disk. I have included an override option /O which forces the user to explicitly specify and to knowingly copy a copy prohibited song. Have look at the file ROYALTY.TXT included in this distribution, which was honourably pinched from the program CDGRAB. It is a list of most country's contacts for paying royalties. I have heard from a couple of people who have actually tried to pay the royalites. They have had nothing but trouble. My understanding is that the producer has the final say on royalties, and that you must deal with him/her as well. One thing to remember is that audio/video fills up the hard disk fast. It takes between 9 and 10 megabytes per minute. Because of this I put in a check to make sure that you will have enough space to put the requested samples. As well there is the /U option which will give you an estimate of how much disk space will be used without actually dumping the data to disk.

Note that the `tracks' on a CD aren't laid out like tracks on a hard disk. The track and index are just numbers that are stored with each sector on the CD (in the Q-subchannel packet). The start address of a track is stored in the Table Of Contents on the CD, indices are not. Indices are normally not used, except index 0 for the 2 seconds pause at the start of each track. The REAL structure of the CD medium is a large continuous spiral, starting at the center of the CD (at 46mm diameter). Finding a specific sector is not as trivial as it is on a hard disk. You'll have to employ a kind of binary search algorithm. Finding the start position of a specific index is even more difficult as you don't even know where it starts. >|> And every CD player somehow manages to ship the data from the disc to >|> the D/A converter, doesn't it?

Well, most decoders used in audio CD players, output a stream of samples and sub-channel data, mostly used for their time code. As the decoder has to adjust the spindle speed, it uses a FIFO to store the data. If the FIFO fills up, the spindle motor is slowed down, if it gets empty, the motor is sped up. The sub-channel data normally doesn't pass through the FIFO, but goes directly to a microcontroller. That way, the microcontroller can't be sure that it knows the exact address of the data, coming out of the FIFO. To circumvent this problem, the address of a sector is also stored in the data itself, together with a 12 bytes sync pattern. This way, one can determine the starting of a sector and its address just by looking at the data coming out of the FIFO. Here's the real problem: audio sectors don't have this sync pattern, nor the address of the sector, in the data area of a sector. Most CDROM drives use chips that are coming from audio players. The first CDROM drives were just modified audio CD players. To read audio sectors on a CDROM drive, you'll need a special decoder or you'll need to connect a standard decoder with some custom hardware to generate pulses to indicate the start of a sector and to synchronize the sub-channel packets with the real 2352 bytes of data. I hope that this explains it a bit. Adrie Koolen (adrie@ica.philips.nl) Philips Consumer Electronics, Eindhoven, the Netherlands -------------------------------------------------------------------------- Because of this, most every CDROM drive that can read DA frames cannot accurately return to the exact same location on the disc every time. It will usually return within a few samples either way. It took a lot of time and thought to write the code to correct for the "jitter" efficiently. My first try brought the transfer rate to a crawl. I have been refining the process to the point that it barely has any computing overhead, but still I have to read most every frame twice. I am still working on getting this to work faster. Some people have reported an 8x slowdown from 0.9a to 1.0a. I have no explaination for that large a difference. It is nowhere near that large on my machine, as I see only about 3x. I do agree that it is still much too slow. I have made a number of improvements in 1.0e and 1.0g that help with this slow down including making the receive buffer as large as possible (64K) when using real mode drivers like ASPI and MSCDEX. I have also added the /NJC option for those who cannot wait for their files to be created, or for those whose drives are generating "Jitter greater than 5 frames" errors. This error means that the software has become lost on the CD because the drive was unable to return to within 5 frames of its last postion.

Registered users will receive a key file to "unlock" all of the new features added in version 1.6. There is NOT a pro version available for an unreasonable sum of money. As I said at the start of this file, I am now forced to start asking for a small amount of money for this program. If you use it, then you need to register it. If you don't agree with the new shareware policy, then you can: a) use the program anyway and violate the copyright b) go back and use version 1.0h which will remain freeware c) don't use the program at all I would rather keep this program Freeware, but when it starts costing me money to develop new features, then I have to draw the line. The registration fee for using CDDA is now $15 US. I believe that this is a fair amount given the amount that the program does. As well, if you don't need the new features and bug fixes, then use the old version. I won't be asking for a fee every time a new version comes out. This fee will give you a lifetime (as long as I bug fix and add features) of free updates via the Internet. I will also notify registered users of any new versions for a year. ****** Note: my mail address has changed from the one in version 1.5 and earlier !!!!

This program is so slow because of any one or more of the following: 1. My poor programming skills. 2. Many of the CDROM drives only read DA frames in 1X mode even though they may transfer data at 2X or 3X or faster. 3. The amount of computing to do jitter correction. 4. Reordering the bytes from the CD to the WAV file. 5. Having to read 16 frames for every 10 actually written to disk to allow for up to three frames of jitter. This has been improved with the use of /block and /overlap 6. When there is more than three frames of jitter, I slightly shift the aim of the search and reread the problem frames. 7. My Toshiba seems to have a magic number of 10 frames, that if I read more than that at a time it takes 2-3 times longer than reading in bunches of 10 or less. I don't understand it. Since I have to read ahead 3 frames and behind 3 frames every time I read a block from the drive to correct for jitter, I can't very well keep my reads under 11 frames. Other drives may have similar thresholds. 8. If you are using MSCDEX only, make sure that the /m:xx option on the MSCDEX line of your autoexec.bat is set to at least 20. Any less than this, and CDDA will end up reading in 2 possibly discontinous chunks. This will add greatly to the time to read data. 9. Many drives are happy reading contiguous frames from the disc. If you ask it to move it's start point to a frame that it has just read, it may take a very long time to get itself all lined up to start reading again. A good example of this is the Philips CDR drive that reads with /NJC at 2x speed but takes 6 times longer than the range selected if it keeps having to resychronize itself. What is ASPI? ASPI stands for Advanced SCSI Programming Interface. It was developed by Adaptec, and has been adopted by many SCSI card manufacturers as a standard SCSI programming interface. If you want more information on ASPI call Adaptec (408) 945-8600. When I use /T, the start and ends of the track are a couple of seconds away from where I think they should be. Why is this? In version 0.9a, there was a deep rooted bug which caused this. I have fixed it (I hope), and this should no longer be a problem. When I play back my samples, why are there pops and clicks? These pops and clicks can come from two places: 1. version 0.9a did NOT handle the jitter problem, it is handled now. 2. your sound card can't handle 16-bit 44.1 KHz samples. Try using SOX or a similar program to change the sample to 22.05 or 11.025 KHz samples and try again. 3. Many CDs have been mastered from digital sources. In this case the source may have been synthesized digitally which gives absolutely perfect sounds which are very repetitive and exactly the same. When this happens, it may possibly confuse the jitter correction routines. There is not a lot I can do about it at the moment, and there is less that any of the other programs like mine can do. The program stops with the error xxx. What is wrong? The 0.9a release had very limited error reporting. I thought that if it worked on my machine it work on everybody's. This version has much more error reporting. As I understand it, CDDA will not necessarily work correctly if SMARTDRV is installed. This has been the source of a lot of trouble. As well some people have been having trouble using CDDA in a DOS window in Windows. I think there may be a problem when being used with a DPMI manager installed. So, the bottom line is DON'T run CDDA under Windows. When will you release an OS/2 version? I have no interest in writing a version for OS/2. Period. However, if you are running Warp, then you already have VASPI, and CDDA should run just fine. If you are using an earlier version, then there is a program from Adaptec called VASPI, which will allow you to run CDDA in a DOS window. I got the following email with the how-to for OS/2 from Stefan Eichner (Stefan-Eichner@k2.maus.de): > 1. Your CONFIG.SYS has to include the follow lines: > [...] > BASEDEV=TMV1SCSI.ADD > BASEDEV=OS2ASPI.DMD > REM DEVICE=C:\OS2\OS2CDROM.DMD /Q > E=C:\OS2\MDOS\VASPI.SYS > [...] > !If no OS2CDROM.DMD is loaded you can't read Data-CDs! > > 2.

Change the settings of the DOS-Session on the WPS: > DOS_DEVICE=C:\TSLRCDR.SYS /d:mscd001 /p:3 > > Now CDDA works great!!! VASPIBET.ZIP is available from ftp.cdrom.com When will you release a Windows version? I have no interest in writing a Windows version. I don't have the time, and I don't think Windows is a particularly good OS (if you can call it an OS). I have had a couple of offers to help, but I have been too busy with the rest of my life to work on it. Don't hold your breath. The word from the beta testers is that CDDA runs just fine in a DOS window under Windows 95. Why doesn't CDDA work under Windows NT? First, Microsoft chose not to fully support the device drivers for CDROM drives to allow reading DA. This means that if you are trying to use the /M option to read DA, you can't. Second, Microsoft chose not to include ASPI drivers with NT. You can get Win16, and Win32 ASPI drivers from Adaptec for NT, but CDDA can only talk to DOS ASPI drivers. Maybe someday, I'll get around to writing a version of CDDA that can talk to Win16 or Win32. When will you release a UNIX version? Never. Although I run LINUX on my machine, I have no interest in rewriting CDDA. There is a program called CD-DA for Linux, which should work with the Toshiba drives. It is available from Sunsite. When will you be writing a version for my CDROM drive? Getting the programming information from CDROM drive manufacturers is like pulling teeth. I've been hunting for this stuff for over two years, and have only managed to get the programming manuals for Toshiba, Chinon and Sony. If you have a drive and it does support DA frames, I need the programming manual. I also need about 5 or 6 extra hours in each day. I have a Toshiba drive. Why doesn't your program work? It appears that different ROM revisions cause the drives to work differently. For instance, my Toshiba 3401 is revision 0283. I have heard from people who have ROMs older and newer that can't use my program. I have also heard that Toshiba has changed the programming interface on newer drives, but it is not reflected in their SCSI programming manual. I just don't know what is wrong. Why doesn't your program work with my ASPI driver? Several vendors supply ASPI drivers for their SCSI cards. However, all drivers are not created equal. I have heard from people who have had trouble with just about every SCSI card on the planet. I only have Adaptec's EZSCSI to do my testing. I'll try and do my best on case by case basis, but I really don't have any spare time. I also hear from a number of people who have trouble using the Adaptec 1520/22 controllers. It appears that the delay in doing polled IO from this card screws up my view of how the controller and drive interact. Don't expect any fixes soon. CDROMINF works on my machine, so why doesn't CDDA? CDROMINF only uses MSCDEX calls, and CDDA also uses ASPI calls. It is these ASPI calls that do the meat of the program. If ASPI isn't on your machine, or doesn't work correctly, then CDDA will never work. Your only other choice is to try the /M option and use only MSCDEX commands. This is unlikely to help any SCSI drive owners. Before writing me and asking for your drive to be supported, do a little legwork first. Call the manufacturer and ask for the programming information. Second, run all the test programs included with this release. These programs don't check for the drive type before trying to read DA frames. If any of these pass, let me know and I can add your drive based on the programming information of an existing drive. It has happened before, so it might happen again. Why are there tons of zeros at the beginning and end of my track? Most every audio track has some silence at the beginning and end. This silence is actually digital silence which is all zeros for the samples. Can I use CDDA to read from DAT drives? As far as I know there are only a couple of DAT drives out there that allow reading of digital audio through SCSI. In theory, I could add that feature to CDDA, but since I don't have one of those drive, and I don't have the programming manuals either, I seems very unlikely that this will ever happen. It also seems that these drive vendors have taken out support for reading DA. Their story is that people were putting cheap quality audio tapes in the drives and screwing up the drives. So they took out the feature. My guess is that they were getting pressure from the record companies. If you really need to do this then get yourself a Silicon Graphics machine. They make sure that this feature is available in their package. Don't forget to mortgage your house to pay for it. The only other option at this point is to get a DAT player that has a digital out port and get a card for your PC that can handle the digital stream. These cards are widely available and shouldn't cost you more than a few hundred dollars. Sometimes CDDA doesn't work when I first put in a CD. Why? I don't know. Some people have reported that CDDA works better after a new CD is put in the drive if you use some other utility to play and then stop the CD. This seems to force some sanity into some drivers. Can you change CDDA to read the song titles from my audio CD? There are no song titles recorded on an audio CD. The following is a post which explains this better than I can. A very few CDs that support Philips Blue Book, do have the song titles in a "hidden data track". My most recent version of CDROMINF will display this information. ---------------------------------------------------------------------------- From: dplatt@ntg.com (Dave Platt) Newsgroups: alt.cd-rom Subject: Re: Ascii Track data on Audio CDs Keywords: Audio CD Ascii Track Date: 23 Feb 93 19:16:03 GMT Organization: New Technologies Group, Inc.

The disc table-of-contents has information about the total disc length, number of tracks, and the starting time of each track. It has no room for human-readable text and there is no provision in the standards for such, as far as I've ever been able to find out. The audio tracks have "subcode" information associated with each frame (75 frames per second). The P subcode bit is used for primitive track-signalling flags, and is rarely interpreted by modern CD players. The Q subcode contains some useful information: control (type, preemphasis, and copy-protect fields), address information, index numbers, and sometimes the disc catalog/barcode number or the ISRC code (serial number, country, year, owner ID) of the recording. Still, no room for text or artwork. The R,S,T,U,V,W bits in the subcode can be used in a variety of ways. The most popular de facto standard is for CD+G graphics. These provide a sort of slow-scan video (288x192 pixels, max of 4096 colors using an encoded color lookup table). The CD+G graphics can include almost anything... lyrics, still photos from concert footage, and copies of the cover artwork are all quite possible and have been done. Only a relatively small percentage of audio CDs have CD+G graphics. Some CD players have a "subcode out" jack which can be fed to an external decoder. Some CD-ROM drives allow the subcode data to be read over the SCSI (or other) communication bus while the drive is playing audio CDs through its built-in DACs. Some [fewer] drives allow both the audio data and the subcode to be retrieved over the bus and manipulated by the host computer. Details vary; see your drive reference manual. -- Dave Platt VOICE: (415) 813-8917 Domain: dplatt@ntg.com UUCP: ...netcomsv!ntg!dplatt USNAIL: New Technologies Group Inc. 2470 Embarcardero Way, Palo Alto CA 94303 ---------------------------------------------------------------------------- Changes in version 1.7 from version 1.6 - a number of bugs have been fixed in the new features from 1.6 - a major bug which caused the program to hang on some machines has been fixed - fixed a bug in the drive identification routine that was not recognizing some drives Changes in version 1.6 from version 1.5 - please note my new mail address: Jim McLaughlin 337 Nautica Ct.

Changes in version 1.0h from version 1.0g - bug in displaying the sense data has been fixed. - a major bug that caused the program to hang at random has been fixed. - Mitsumi 4x, Sony 55E, Sony 8012 drive types added - Plextor (Texel drives 3028 and 5028 have been removed. I included them based on a rumour I heard. I have since received the programming manual for these drives, and they do not support reading DA frames. Changes in version 1.0g from version 1.0e (version 1.0f was not formally released) - ISRC code display added - option NJC added - Hitachi, Teac, Matshita drive types added - bug in MSCTEST concerning empty buffers fixed Changes in version 1.0e from version 1.0a (versions 1.0b to 1.0d were not formally released) - UPC code display added for NEC drives - Toshiba mode select to return the drive to normal operation after reading DA frames had a conflict with EZSCSI drivers - this has been fixed - length of WAV file did not always match length contained in header - this has been fixed - added support for the Chinon CDS-535 drive (since I don't have one of these drives, this is untested) - added support for the Plextor 3028/5028 drives (since I don't have one of these drives, this is untested) - there was a bug which on some machines would allocate memory wrong when using the /M option, and would fill the file with zeros - this has been fixed - program TOSH_RST was added for users of the Toshiba drives who have CDDA exit with a major error. It resets the drive back to normal operation - there was a bug on some machines that would allow the user to run CDDA fine, but the respective test program would fail. It appeared mostly on the SONYTEST and NECTEST programs - this has been fixed - during running with NEC drives extra debug messages were printed - this has been fixed - the jitter correction routine has been rewritten - CDDA now runs about twice as fast as 1.0a did on my machine - a problem with one version of the Sony rom has a peculiar failure which may be corrected by a rewrite of the sector search routine - a problem with copy permitted discs sometimes required /O in order to dump to disk - when the last track of a disc or the last LBA or the last MSF was selected to be dumped, some drives actually only allow reading of the second to last frame, and not the last frame. since there is virtually no sound on the last frame of the disc, I have forced the program to stop at the next to last frame Known bugs: - someone has reported the program failing on a very large drive with very large amounts of disk space available. The specific example was a 250M drive with 235M free. It would appear that there is a bug in the Borland dfree routines. I will be looking into the problem, except for the fact that my drive is only 100M, so I can't duplicate it. Note I haven't seen this problem for a long time, so I would assume that it has gone away. - a couple of people have reported that the WAV files created are not compatible. I can't say much except that in one case the file size written in the WAV header was incorrect, and I don't know why. I have however found that really large WAV files (>10M) often confuse some players. I have seen a file work correctly on a couple of players, and not on others. My guess is that some players out there are not interpreting WAV files correctly, or are not expecting very large files. I have written the program WAVDUMP, which will dump out the WAV file header information to see if there is anything wrong with the header. - one person reported that running the test programs on their machine and specifying a hard drive instead of a CD-ROM drive causes the number of bytes per sector to be changed permanently on the drive I don't know if this was just a fluke, but be careful. I have included the program TOSHREPR.EXE. This program will reset the sectors per track to 512 when you accidentally run TOSHTEST on a hard drive instead of the CDROM drive. This problem appears to manifest itself on hard drives manufactured by DEC. If you use these drives be careful when running TOSHTEST. - one person reported that having more than one CDROM drive means trouble for the /T mode. I'm looking into it, but don't have an answer yet. I haven't heard this one in a while, so I am assuming that the problem has gone away. - there appears to be a problem with the LIT on some CDi Green book CDs. It seems that MSCDEX is getting confused as to when the CD starts which in turn confuses CDDA. I'm looking into the problem. - there is a bug in the MSCDEX driver in Win95 when you are using a new CD-Enhanced disc. It gets confused and thinks that the first audio track number is one more than the last audio track. I have a work around for the problem by assuming that the first track on one of these discs on Win95 will always be number 1. - there are a number of bugs in the ASPI drivers in Win95. 1) There is support in CDDA to talk directly to ATAPI drives instead of talking through MSCDEX. This would allow the user to not have to load the DOS drivers just to get CDDA to work. On every machine I have tried, this method only partly works, but not enough to pull a whole track off the CD. I have left the code in the program in the hopes that Microsoft will fix their ASPI driver and then my software will work. 2) There appears to be an upper limit of 64K for any data transfers through ASPI. Because of this the values of block+2*overlap cannot be more than 27. The following is the error messages you get when you try. --------------------------------------------------- ASPI request error: fffd Sense data: sense key: 0, asc: 0, ascq: 0 Unknown: 33 Sense data: sense key: 0, asc: 0, ascq: 0, valid: 0, error code: 0, segment #: 0, ili: 0, eom: 0, fm: 0, info 0: 0, info 1: 0, info 2: 0, info 3: 0, as len: 0, csi 0: 0, csi 1: 0, csi 2: 0, csi 3: 0 ----------------------------------------------------- - the average data reading speed values that are given at the end of a transfer are somewhat inaccurate when very short samples are used. The values become very accurate for longer samples. The same sort of difficulty can be found when using the /DL option. - the /DL option should only be used when saving WAV or BIN files - the values returned for AIF files will be incorrect --------------------------------------------------------------------- The following is what is displayed on my machine when I dump a small block of audio.
