A third source of compression is a version of Huffman encoding called Rice encoding.
Rice codes are special Huffman codes that can be used in this context. A parameter is
dynamically set and changed based on the signal’s distribution, and this parameter is used to
generate the Rice codes. Then the table does not need to be stored with the compressed signal.
FLAC is unpatented and open source. The FLAC website is a good source for details and
documentation about the codec’s implementation.
