ADPCM_dec v1.9a  (C) 2005-2007  Lorence Lombardo.


This is my attempt at writing an ADPCM decoder for Christian Buchner's ADPCM
package. See the archive "ADPCM_Package.lha" on the aminet.

ADPCM2's and ADPCM3's appear to be decoding correctly now.

Usage is as follows:-

 ADPCM_dec <ADPCM_file> <output_file>

 Provide no <output_file> to play via AHI.

 Use the extensions `.AIFF', `.8SVX', `.WAV', `.SUN' and `.DEC'
 for the output file name to save in those formats via the
 `sndfile.library', otherwise the output file will be in raw
 format.


See the files "ParaMiAmiga.lha" and "dancing.lha" from the aminet for
examples of an ADPCM2 and ADPCM3 respectively.

Also try encoding a stereo standard AIFF (16bit 44100Hz) with Christian
Buchner's "Hifi2ADPCM" to get a better idea of its output quality.

Thanks to Bernd Roesch for his assistance on the asm routines.
