Here's my ADPCM/etc. codec library: https://github.com/ZILtoid1991/libPCM

I have an intent to keep a mostly GC version (where the codecs are still noGC for minimal CPU overhead, so the best of both worlds), I'm planning an embedded version without the file operations, and one that has the file operations but don't depend on the GC. I had some attempt at this, but gave up due to the complexity of working with multiple pointers (and with pointers to pointers).

Some suggestions on it? Also feel free to either suggest new codecs (G726 will be my next target).
