A quick look through /usr/demo/sound/sound.c and the related .h files will
tell you that the format the files are in is called uLAW format. (that's
actually Mu-LAW format). It appears that the chip can handle aLAW and
straight binary formats also, but I'm not sure how.
The sampling speed is 8k samples/second. Each waveform sample is stored
in one byte in uLAW format. uLAW format is a simple data compression
format designed to store audio waveforms in one-byte samples.
I will post my sampled-binary to uLAW conversion program soon, there has
been enough interest in it.
