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.
