ADPCM_enc v2.0a  (C) 2009-2014  Lorence Lombardo.


WTF is ADPCM_enc ?

ADPCM_enc is an encoder for Christian Buchner's ADPCM format, using the
ZyXel compression algorithm.

ADPCM_enc can even encode into 8SVX-FDC/EDC.

ADPCM_enc can even encode into my very own 8SVX-ADPCM implementation.

ADPCM_enc will also encode into the my very own LLADPCM format.

LLADPCM should be considered as the successor of 8SVX-ADPCM/FDC/EDC.

LLADPCM is stereo stream friendly and has a default comment of the date and
time of encoding. The default comment can be changed by the following:-

setenv LLADPCMcom "some other comment"

The following line is reserved for no comment:-

setenv LLADPCMcom NULL

The following line is reserved for the comment file "ram:LLADPCMcom.txt":-

setenv LLADPCMcom COMFILE


Unlike 8SVX-FDC/EDC, LLADPCM-FDC/EDC does not need to read a pad byte
followed a reference byte, because LLADPCM-FDC/EDC will always start with a
zero byte reference.

Developers interested in supporting the playing of LLADPCM should refer to
the archive "ADPCM_dec.lha" on the aminet for more information.


ADPCM_enc can encode almost any uncompressed AIFF/C, RIFF-WAV and MAUD file
types, including float 64.

ADPCM_enc is also "PIPE:" friendly.


 Usage:-

 ADPCM_enc <in_file> <out_file> <method> [bit] [fre] [chan] [I/U/F] [F]

 <method> can be one of:- 2, 3, 82, 83, 82M, 83M, 8, 8M, 8F, 8E, 8FM, 8EM,
                          L2, L3, L2M, L3M, L4, L5, L4M or L5M.

 I=intel, U=unsigned, F=float

 Use `meth' for the input file for a <method> description.

 eg. ADPCM_enc Noonan.wav Noonan.adpcm 2


If the first three optional parameters are supplied after the "<method>"
parameter, then the input file will be treated as RAW data.


When encoding into stereo 8SVX it is recommended that you write to "RAM:" if
possible for a significantly improved peformance.


See the following archive's on the Aminet for related interest:-

"ADPCM_dec.lha", "mp3toSV.lha", "playOGG.lha", "ADPCM_Package.lha",
"8svx_comp.lha" and "LLAD_com.lha".
