Hi,
alac_decoder is a basic decoder for Apple Lossless Audio Codec files
(ALAC). It is a C implementation of a decoder, written from reverse
engineering the file format. ALAC uses an adaptive FIR prediction
algorithm and stores the error values using a modified rice or golumb
algorithm.
Works well on i386/amd64.
ok?

Please add this, then it's ok sthen@
MAKE_FLAGS = CC=${CC} CFLAGS=${CFLAGS} -Wall

This is the original reverse engineered decoder that the alac code in ffmpeg is based on. Is there any reason to prefer this over the code in ffmpeg or the code apple recently released (http://alac.macosforge.org/) ?

I've been using shntool to convert alac files with cuesheets to individual flac files. It uses alac_decoder at runtime to do this. -- Anthony J. Bentley
