demac - a decoder for Monkey's Audio files. Introduction demac is an implementation in portable ANSI C of a decoder for the Monkey's Audio lossless compression format. It has the following features: * Open source (GNU GPL) * Written in portable ANSI C * Designed for use on low memory and embedded devices. All internal buffers are statically declared - the core library doesn't require malloc/free. This has the disadvantage that the library isn't re-entrant. Compatibility libdemac is still in the early stages of development but has been relatively well tested with v3.99 files at all compression levels. v3.97 files have received less testing - 16-bit files seem to work, but 24-bit files are causing problems in the range decoder. Files earlier than v3.97 are not supported by libdemac, but support might be added in the future.
