- PlayCDDA - Play audio CDs on your Amiga's audio.device
- ------------------------------------------------------

- Version 1.1 04-Jan-94 (C) 1993 by Frank Munkert

-
- INTRODUCTION
-
- PlayCDDA is a program for owners of Toshiba 3401 and Apple CD-300
- CDROM drives. These drives are capable of transferring CD-DA
- (digital audio) data over the SCSI bus. PlayCDDA reads this data and
- reproduces the corresponding sounds on the Amiga's audio.device.
-
- DISCLAIMER
-
- This software is provided as-is, without warranty of any kind,
- either expressed or implied. In no event will the author be liable
- for direct, indirect, incidental or consequential damages or data
- loss resulting from the use or application of this software. The
- entire risk as to the results and performance of this software is
- assumed by the user.
-
- REQUIREMENTS
-
- AmiCDROM should work with any Amiga model which has a "SCSI-direct"
- compatible SCSI bus adapter. A Toshiba 3401 or Apple CD-300 CDROM
- drive must be connected to the SCSI bus.
-
- Your SCSI bus setup must have a bandwidth of at least 173 KB/sec in
- order to transfer 44100 4-bit-samples per second. The higher the
- bandwidth, the better. Also, while running PlayCDDA there shouldn't
- be much other activity on the SCSI bus (e.g. hard disk accesses).
-
- INSTALLATION
-
- Copy the file 'PlayCDDA' to your favourite location for executable
- programs.
-
- USING PLAYCDDA
-
- Invocation from CLI
- You have to supply the name of your SCSI device and the
- SCSI unit number of your CDROM drive as arguments to PlayCDDA,
- e.g.
-
- PlayCDDA scsi.device 1
-
- invokes PlayCDDA with SCSI device name "scsi.device" and
- unit number 1.
-
- The complete command line template for PlayCDDA is
-
- DEVICE/A,UNIT/A/N,CHIP/S,FAST/S,DMA/S,ANY/S,LOW/S,MEDIUM/S,HIGH/S
-
- DEVICE: scsi device name
- UNIT: scsi unit number
- CHIP: use chip memory for CDROM buffers (this is the default)
- FAST: use fast memory for CDROM buffers
- DMA: use 24 bit DMA memory for CDROM buffers
- ANY: use any available memory for CDROM buffers
- The options CHIP, FAST, DMA and ANY are mutually exclusive.
- LOW: low volume
- MEDIUM: medium volume
- HIGH: high volume
- The options LOW, MEDIUM and HIGH are mutually exclusive.
-
- Invocation from WorkBench
- Edit the tooltype entries "DEVICE" and "UNIT" of the PlayCDDA icon
- such that they reflect your system setup.
- Double-click on the PlayCDDA icon.
- The optional tooltype "MEMORY" may have the values "CHIP", "FAST",
- "DMA" or "ANY" (see above).
- The optional tooltype "VOLUME" may have the values "LOW", "MEDIUM"
- or "HIGH" (see above).
-
- PlayCDDA communicates with the user over a simple graphical
- interface. Basically, you have to click at the button for the
- track you want to hear, and PlayCDDA starts playing this track
- on your Amiga's loudspeaker.
-
- The rest of the section explains the individual buttons of the
- user interface.
-
- "Start"
- Click at this button to play the first track.
-
- "Stop"
- Stop playing.
-
- "1" ... "20"
- Click at on of these buttons to play the corresponding track.
-
- "Next"
- Plays the next track.
-
- "Prev"
- Plays the previous track.
-
- "Volume"
- Adjust the volume of the sound reproduction.
-
- "Sampling rate"
- The number of bytes per second that are sent to the audio.device.
- The higher the sampling rate the better the sound quality.
-
- "Buffers"
- Number of buffers. The higher the number of buffers, the lesser is
- the chance that the sound may be interrupted by other tasks with
- higher priority.
-
- You should adjust "Buffers" and "Sampling rate" to fit your system's
- need. On an Amiga 3000T with built-in SCSI device, the default settings
- should work. With an Apple CD-300 it might be necessary to set the
- number of buffers to 64 for increased performance.
