Bonk is an audio compression program that can operate in either lossy or lossless mode. In lossy mode, it achieves around 14:1 compression while remaining perceptually lossless; equivalent to around 95 kbps for CD quality stereo. In lossless mode, which allows exact recovery of the original audio file, the compression ratio is typically around 2:1. The compressed files are stored in a new format based on speech compression techniques. Compressed files can then be converted back to an uncompressed format or played back in real time.

Recent releases


Release Notes: Support for BSD variants was added. The bitrate for tonal sounds now automatically increases. The code now compiles with gcc 3.1.


Release Notes: This release removes a clipping problem, features a more elegant (and faster) encoding algorithm, slightly improves decoding speed, and is now endian safe for playback (ie. can now playback on PowerPCs).


Release Notes: This release features reducing of the default quantization level, better reproduction of high frequencies, a better speech compression mode, options to specify the output file, and artist name and track title setting.


Release Notes: The warbling artifact that appeared for recordings containing very pure tones has been removed.
