*** wav2swav ***

Converts WAV files into SonaWave (Sona's PCM format). Usage is (if the source
file is "input.wav" and the converted file will be "output.swav"):

   wav2swav input.wav output.swav

WAV file must meet these requirements:

   - must be uncompressed PCM
   - must be mono or stereo
   - must be 8-bit or 16-bit
   - sample rate can be anything

Unless you have some unusual WAV file, this shouldn't be a problem. The tool
takes care of resampling to the intended format.
