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. + + +Source Code + +The source code in this directory is structured as follows: + +demac/Makefile - Makefile for the standalone demac decoder +demac/demac.c - Simple standalone test program to decoder an APE file to WAV +demac/wavwrite.[ch] - Helper functions for demac.c +demac/libdemac/Makefile - A Makefile for use in Rockbox +demac/libdemac/*.[ch] - The main libdemac code + + +Latest Version + +The latest version of demac and libdemac can always be found in the +"lib/rbcodec/codecs/demac/" directory in the Rockbox source. You can check +this out from svn with the command: + +svn co svn://svn.rockbox.org/rockbox/trunk/lib/rbcodec/codecs/demac demac + +Or browse the source code online here: + +http://svn.rockbox.org/viewvc.cgi/trunk/lib/rbcodec/codecs/demac + + + +Acknowledgements + +Thanks to Matt.
