description      Basic decoder for Apple Lossless Audio Codec files
long_description This is a basic decoder for Apple Lossless Audio Codec files (ALAC). \
                 ALAC is a proprietary lossless audio compression scheme. Apple never \
                 released any documents on the format. What is provided here is a C \
                 implementation of a decoder, written from reverse engineering the \
                 file format. It turns out that most of the algorithms in the codec \
                 are fairly well known. ALAC uses an adaptive FIR prediction algorithm \
                 and stores the error values using a modified Rice or Golomb algorithm. \
                 This program will not be able to handle all ALAC files, it can only \
                 handle mono or stereo files. ALAC allows up to 8 channels. The ALAC \
                 decoder supports both 16 and 24 bit sample sizes. The decoder is fairly \
                 self explanatory, it can read an ALAC stream from either a file or from \
                 stdin, and write it as raw PCM data or as a WAV file to either stdout or \
                 a file. In theory one should be able to stream data to the decoder.
