      PortSystem 1.0
      Name: alac_decoder
      Version: 0.1.0
      Category: audio
      Maintainers: nomaintainer
      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 I provide 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 golumb algorithm.
