|  | From version 1.0.18, libsndfile also reads and writes | |||
|  | [FLAC](https://xiph.org/flac/) and [Ogg/Vorbis](https://xiph.org/vorbis/). | |||
|  | 
 | |||
|  | From version 1.0.29, libsndfile can read and write | |||
|  | [Ogg/Opus](https://opus-codec.org/). | |||
|  | 
 | |||
|  | 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. | |||
|  |

|  | If you are interested in how to add a new format to a libsndfile, you may find | |||
