Description:
Free Lossless Audio Codec - command line tools
FLAC stands for Free Lossless Audio Codec. Grossly oversimplified, FLAC is similar to MP3, but lossless. The FLAC project consists of: . * The stream format * libFLAC, which implements a reference encoder, stream decoder, and file decoder * flac, which is a command-line wrapper around libFLAC to encode and decode .flac files * Input plugins for various music players (Winamp, XMMS, and more in the works) . This package contains the command-line tools flac (used for encoding and decoding FLACs) and metaflac (used for manipulating FLAC metadata.)
