FLAC
About
FLAC stands for Free Lossless Audio Codec. FLAC is an audio compression codec that is lossless. Unlike lossy codecs such as MP3 and Vorbis, it does not remove any information from the audio stream.
On January 29th, 2003, Xiphophorus (now called the Xiph.org Foundation) announced the incorporation of FLAC under their xiph.org banner, to go along with Ogg Vorbis, Ogg Theora, and Speex.
