FLAC is a free (open source) lossless format. During compression, FLAC does not lose quality from the audio stream, as lossy compression formats such as MP3, AAC, and Ogg Vorbis do.
FLAC reduces bandwidth and storage requirements without sacrificing the integrity of the audio source. A CD disk encoded to FLAC can be decompressed into an identical copy of the audio data. Audio sources encoded to FLAC are typically reduced to 50–60% of their original size.
FLAC lossless is being used by a small but growing number of online music stores.
FLAC offers identical playback sound to CDs, with support for tagging, cover art and fast seeking; and is supported by many software applications. FLAC playback support in portable audio devices and dedicated audio systems is limited compared to lossy formats, but is supported out of the box by more hardware devices than competing lossless formats and has a growing number of converts.
