VoxMail is a small application intended as example source code. It was meant to demonstrate the voice recording API added in the Hiptop 2 OS builds. Recording sound was great, but the files were huge WAV files. As such, I wrote an ADPCM encoder to compress the audio somewhat. I also discovered that the hiptop had a (buggy) built-in AMR encoder.

I have included the source archive here from my source code archive. I don’t know if it works, as I could have left developing it in the middle of something. Also, an old zip file (I think a pre-AMR version) is included as well. Again, I’m not sure in what state the source code was left.
