FLAC
FLAC is short for Free Lossless Audio Compression. It is a codec and file format which provides a perfect quality audio file. Normally, FLAC files contain CD quality audio.
FLAC provides a smaller size of file than PCM WAV (about half the size), but very much larger than lossy codecs like MP3. MP3s are about 5-10% the size of WAV files, but are lower quality.
A CD's worth of data is...
- 700MB as a CD
- 700MB as WAV
- 300MB as FLAC
- 40MB as MP3 (128 kbps)
