1 | demac - a decoder for Monkey's Audio files. | ||
2 | |||
3 | Introduction | ||
4 | |||
5 | demac is an implementation in portable ANSI C of a decoder for the | ||
6 | Monkey's Audio lossless compression format. It has the following | ||
7 | features: | ||
8 | |||
9 | * Open source (GNU GPL) | ||
10 | * Written in portable ANSI C | ||
11 | * Designed for use on low memory and embedded devices. All internal | ||
12 | buffers are statically declared - the core library doesn't require | ||
13 | malloc/free. This has the disadvantage that the library isn't | ||
14 | re-entrant. | ||
15 | |||
16 | |||
17 | Compatibility | ||
18 | |||
19 | |||
20 | libdemac is still in the early stages of development but has been | ||
21 | relatively well tested with v3.99 files at all compression levels. | ||
22 | |||
23 | v3.97 files have received less testing - 16-bit files seem to work, | ||
24 | but 24-bit files are causing problems in the range decoder. | ||
25 | |||
26 | Files earlier than v3.97 are not supported by libdemac, but support | ||
27 | might be added in the future. | ||
28 | |||
29 | |||
30 | Source Code | ||
31 | |||
32 | The source code in this directory is structured as follows: | ||
33 | |||
34 | demac/Makefile - Makefile for the standalone demac decoder | ||
35 | demac/demac.c - Simple standalone test program to decoder an APE file to WAV | ||
36 | demac/wavwrite.[ch] - Helper functions for demac.c | ||
37 | demac/libdemac/Makefile - A Makefile for use in Rockbox | ||
38 | demac/libdemac/*.[ch] - The main libdemac code | ||
39 | |||
40 | |||
41 | Latest Version | ||
42 | |||
43 | The latest version of demac and libdemac can always be found in the | ||
44 | "lib/rbcodec/codecs/demac/" directory in the Rockbox source. You can check | ||
45 | this out from svn with the command: | ||
46 | |||
47 | svn co svn://svn.rockbox.org/rockbox/trunk/lib/rbcodec/codecs/demac demac | ||
