MT_ADPCM is a cruncher and decruncher for the FP_ADPCM format written in pure
ANSI-C.

Some years ago I was looking for a package that I could port for AROS.
I remembered the ADPCM package of Christian "FlowerPower" Buchner and started
rewriting the ASM code in C.
I didn't get very far. Means the resulting code didn't work.
Over the years I've been coming back to it once in while and lately I made
some progress quickly. Seems I had learned some things over the years ;).

The code was developed on a 64bit Intel Linux system but compiles in VBCC.
I haven't tested it on the Amiga yet. Time is a quite factor these days...

It reads and writes source and destination files in a whole. So it needs
quite a bit of memory. The actual crunch/decrunch functions are layed out
like the ASM version. Using my functions instead should be low effort.

The cruncher supports 8 and 16bit mono/stereo WAV files and 8SVX mono/stereo
files as source. The destination format is 2, 3 or 4! bit ADPCM in mono.

The decruncher supports 8bit WAV and 8SVX mono output.

The 4bit format was implemented using some ideas of the mgetty unix
package.

This is all Public Domain like the original!

Enjoy!
