QUICKSAMPLER is a program for reading digital audio data (CDDA) out
of CD-ROM drives, which are capable of sending digital audio data
(16 Bit) over the SCSI bus.
This data can be saved in a file to a disk.
This version works with TOSHIBA drives.

Kickstart 3.0 is required, but it should also work with Kickstart 2.xx
(not tested).

This is version 1.5!

Features:

QUICKSAMPLER V1.0 can/does...

...save CDDA data (whole songs or part of songs) to a file in a very
   FAST way.
...save the audio data in the fileformats: CDR, RAW, 8SVX
...convert the CDDA data to following samplerates: 44100 (44.1 kHz),
   22050 (22.05 kHz), 14700 (14.70 kHz), 11025 (11.025 kHz)
...change the byte order (MSB [Motorola format] at first or LSB [Intel
   fromat] at first) when saving 16bit data.
...change the audio channels in the file: STEREO, CHANGE STEREO
   CHANNELSIDE (what you normally hear on the left speaker of the CD
   is the right channel in the file and what you hear on the right
   speaker is the left channel in the file), LEFT ON BOTH CHANNELS
   (what you can hear on the left channel on a CD is what you get
   on both channels in the file, the right one has no influence), RIGHT
   ON BOTH CHANNELS (what you hear on the right channel on a CD is what
   you get on both channels in the file, the left one has no influence),
   MONO (the left and the right channel are summed up and devided by 2),
   MONO_LEFT (you will get only the left channel in the output file),
   MONO_RIGHT (you will get only the right channel in the output file).
...offer you a good looking process bar.
...tell you using the GUI how many bytes will have the output file.
...check before writing to disk, if there is still enough place.
   Imagine you want to create a file, which is bigger than the available
   free space on the disk. Then QUICKSAMPLER creates the audio file, sets
   it's size, which is calculated with help of intern routines. During this
   process it can happen that the end of the disk is reached. In this
   case QUICKSAMPLER closes and deletes the file, because it does not
   make sense to write to a file, which wouldn't contain all the data
   you wanted to have in it. Some other programs do not check the free
   diskspace. They simply write the audio data to the file after they
   have created it. So it could happen that during the writing process
   (lets say 1 or 2 minutes later) the end of the disk is reached.
   What now? The user loses time and audio data, which should be in the
   file.
...not waste ram-memory. The allocated memory is determined using
   the WB-tooltype "BUFBLOCKS" or with the CLI-Argument "BUBLOCKS".
   BUFBLOCKS can be a number between 0 and 65. The smaller the number
   is, the smaller is the allocated memory and QUICKSAMPLER must read
   from the CD more often. The bigger the number is, the bigger is
   the allocated memory and QUICKSAMPLER must read from the CD less
   often. Default number is 32. There are 3 buffers that have to be
   allocated. The sizes of them are calculated with the formula
   (BUFBLOCKS*2352/a_number_between_1_and_17) or
   (BUFBLOCKS*2352*2) when data in RAW 16bit STEREO 44.1 kHz are changed
   (CHANNEL processing) and saved. Actually during the reading and
   writing process only 2 buffers are used. Which buffer is used
   depends on the fileformat of the output-file.
...offer you a fast reading and writing routine (also for STEREO 8SVX).
   It is not so compulsory to write such a routine as you might think of.


This is version 1.5.

It includes...

...a speed increased reading and writing routine.

...a check, in which a routine determines automatically if there is
   a CD in drive or even not (with the help of the timer.device).
   In the previous version this check was performed using
   IntuiMessages. But if your CD drive was not mounted, the program
   could not receive an IDCMP_DISKINSERTED or IDCMP_DISKREMOVED
   message. And if you have inserted or removed a CD, QUICKSAMPLER
   could not recognize this diskchange and the display was not
   updated with the data of another CD or it was not cleared if
   no CD was inserted. Because of that you had to quit and restart
   the program to make the diskchange visible.
   This problem is now fixed. Now every 2 seconds the program
   checks if there is a CD in drive or not.

...the default-"device"-name "squirrelscsi.device", because in the
   last version the predefined name "1230scsi.device" caused an
   error, which was the reason for the little fragment "ice", which
   appeared, when you wanted to switch to 14700 Hz with the help of
   the Cycle-Gadget "FREQ". Somehow MaxonC++ has put the last part
   of the string "1230scsi.device", which is "ice", into textfield
   of the "FREQ"-Gadget, which should show "14700".
   This is not a programming-mistake, but surely a compiler-bug,
   because with the now intern used string "squirrelscsi.device"
   this error did not appear any longer.
   This problem is now fixed.

...several intern improvements.
