# libflac # libflac
FLAC stands for Free Lossless Audio Codec. Grossly oversimplified, FLAC is similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see links to the right for supported devices) just like you would an MP3 file.
The FLAC project consists of:
* the stream format
* reference encoders and decoders in library form
* flac, a command-line program to encode and decode FLAC files
* metaflac, a command-line metadata editor for FLAC files
* input plugins for various music players

%description
FLAC stands for Free Lossless Audio Codec. Grossly oversimplified, FLAC is similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see links to the right for supported devices) just like you would an MP3 file.
The FLAC project consists of:
* the stream format
* reference encoders and decoders in library form
* flac, a command-line program to encode and decode FLAC files
* metaflac, a command-line metadata editor for FLAC files
* input plugins for various music players
