FLAC stands for Free Lossless Audio Codec and it is a lossless audio compression technology.

FLAC surpasses MP3 quality by preserving the original soundscape in exact detail but the format reduces the original file size by roughly 30-40%, against to average 90% of the MP3 or other lossy compression schemes.

FLAC files can play on latest iPods and other portable devices, and on home or car compact disk players that support FLAC.
