From version 1.0.18, libsndfile also reads and writes FLAC and Ogg/Vorbis. Some of the file formats I am also interested in adding are: Kurzweil K2000 sampler files. Ogg Speex. I have decided that I will not be adding support for MPEG Layer 3 (commonly known as MP3) due to the patent issues surrounding this file format. See the FAQ for more. Other file formats may also be added on request. History
