Bonk is a an audio compression program that operates in both lossy and lossless modes. The compression method Bonk uses is quite simple compared to other lossy formats such as MP3, and is based on speech compression techniques. It is nevertheless capable of producing a high compression ratio while maintaining good sound quality. In lossy mode, it averages 14:1 compression while remaining almost perceptually lossless. This corresponds to 95 kbps for high quality audio. In lossless mode the original audio file can be recovered exactly. Lossless mode typically achieves around 2:1 compression.
