Nicely done.
If anyone is motivated to test some additional songs,
provide me with
additional test data, or suggest another untested codec, please let me know.

And a BSD style license. Very nice.
Ok, some comments from a sound file specialist :-)
- It would be nice to have a file header that is just a little more
obvious. For instance, the first four bytes of an Ogg file contain
the string 'OggS'.
- Do you have any thoughts/plans on adding metadata like song title,
artist, copyright info etc?
- Audio data other than 16 bit is a must. I would suggest at a minimum
16 bit int, 24 bit int and 32 bit float, for audio.
- Have you thought of putting your codec data inside other standard
container formats like WAV, Caf and Ogg?
- What are your thoughts on having this included in libsndfile?
Cheers,
Erik
