FLAC is a Free Lossless Audio Codec. The FLAC format supports streaming, seeking, and archival, and gives 25-75% compression on typical CD audio. Input plugins for Winamp and XMMS are also provided.

            why to use FLAC ...
            This is from the FLAC faq and pretty nicely sums up why you should use FLAC when you want lossless compression:

            Why use FLAC instead of other codecs that compress more?

            For most users, a small difference in filesize is usually far outweighed by FLAC's advantages: open patent free codec, portable open source (BSD) reference implementation, documented API, multi-platform support, hardware support, multi-channel support, etc. Improving FLAC to get a little more compression is not worth making it more complex and more compute-intensive to decode, and hence, less likely to be supported in hardware.

            If you want really high compresssion (not lossless) check out Ogg Vorbis. Tom (
