You wouldn't modify format_wav under the current method. You can copy it
to format_wav2 to mimic the way GSM wav files are handled by
format_wav49. Then you only need to modify the seek function, and the
header creation/update. After that, you just need to make sure the codec
is set to adpcm so your incoming frames are already in the right format.
