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.
