----------------------------------- *** Flowerpower's ADPCM package *** ----------------------------------- CDRipper documentation This software package is in the public domain. Do with it whatever you want. Introduction ------------ This program will rip CD audio data from any audio CD using a Toshiba CDRom drive and store this in ADPCM2 or ADPCM3 format. The loading routines are derived from my 14 bit CDPlayer available on AmiNet. Sony CDRom support will be added in the next release as well as to my 14 Bit CDPlayer. Technical Info -------------- The CD-DA data will be converted to MONO and downsampled to 22050Hz. Then it will be compressed using ADPCM2 or ADPCM3. The ADPCM algorithm is taken from example sourcecodes for the ZyXEL modem's voice files. Usage ----- This is a Shell-only program. Do not try to start it from Workbench. A user interface may be added in the future. Template: TRACK/N/A,TO/K/A,BITS/K/N,DEVICE/K,UNIT/K/N Example: CDRipper 5 TO RAM:Sample BITS=3 DEVICE=gvpscsi.device UNIT=2 TRACK/N/A The audio track to rip. Be careful: No further checks are done on that number! TO/K/A This keyword must exist. After that you must specify a file name to save the sample to. BITS/K/N Either specify 2 or 3 for ADPCM2 or ADPCM3 compression. Other values might be added in the future (e.g. 8 or 16 for saving as IFF or WAV file) DEVICE/K The SCSI device driver to use. This defaults to "scsi.device" UNIT/K/N The SCSI unit to use. This must be a CDRom unit. This defaults to 3.
