From version 1.0.18, libsndfile also reads and writes FLAC and Ogg/Vorbis.
From version 1.0.29, libsndfile can read and write Ogg/Opus.
From version 1.1.0, libsndfile can read and write MP3.
Some of the file formats I am also interested in adding are:
- Kurzweil K2000 sampler files.
- Ogg Speex.
Other file formats may also be added on request.
