ADPCM compression
#4
This is really cool stuff @Petr! 
I still haven't gotten around to making use of your AVI code (saving webcam video to a file) and now this! 

One thing I want to do is make a simple recorder / overdub program, that plays a WAV file only in the left channel and lets the user record along with it in realtime from the line in, and writes the result to a new WAV file with old audio in left channel and new audio in the right, and lets the user "mix" the result by adjusting the left / right volume. Or better yet a simple 4-track recorder. 

Another one would be a kind of "rap music generator" that takes text input, and records it with text to speech, and breaks down the syllables to match the rhythm of a given beat (where the user can choose between different time signatures and bpm, e.g., 4/4 at 120 bpm). I was even looking for of ways to assign musical notes or pitches to the voice so it could sing (which is why I started converting the old SAM software automated mouth which uses formative speech synthesis which can do pitch/singing, see my post on that). 

Anyway, your WAV file code is neat, I'm looking forward to playing with it to generate sound effects and music in stereo in the future. Thanks for sharing.
