- SHORT: play and save digital audio
-
- Read audio data from a CD-DA disk (normal audio CDs) and play back
- via audio.device (22kHz) and store to outputfile (stereo, 16bit signed,
- big endian, 44.1kHz, suitable for 'sox').
-
- usage:
-
- cdda START,LENGTH,TRACK,VOL/N,FILE,16BIT/S,MONO/S,LIST/S,DEBUG/S,BUFS/N
-
- START = startblock
- LENGTH = number of blocks
- TRACK = start relativ to track number
- VOL = volume in percent (0..800)
- 16BIT = experimental high resolution mode
- MONO = map stereo to single channel (for audio output only)
- LIST = show table of contents
- DEBUG = print lots of debugging info through debug.lib (use sushi!)
- BUFS = number of CD blocks to do in a single read.. default is 16
-
- You can use the environment variables CDDA_DEVICE and CDDA_UNIT to choose
- something else than the default ("scsi.device" and 2).
-
- There's a tiny program called 'led' in the archive which toggles the
- audio lowpass filter on newer machines. Disabling the lowpass filter
- will usually get better audio quality but may cause aliasing distortion
- depending on the bandwidth of your speakers.
-
- The program has been tested and used successfully with the Apple CD300,
- Toshiba XM3401B and XM4101 drives. It may or may not work with other drives.
