FLAC : le codec audio sans perte (non destructive)

Le codec Flac permet aux audiophiles de profiter de fichiers sonores identiques aux originaux sans aucune pertes liées à une recherche "excessive" du rapport qualité-taille du fichier.
Avec les actuels espaces de stockage, ce codec mérite, sans aucun doute, toute notre attention. Ce n'est pas du mp3/vorbis (compression moins bonne en flac) bien sûr mais cette page vaut le coup d'oeil :
http://flac.sourceforge.net/features.html
Quelques extraits :
FLAC stands for Free Lossless Audio Codec. Grossly oversimplified, FLAC is similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see links on the main page for supported devices) just like you would an MP3 file.
(...)
What FLAC is not:
* Lossy. FLAC is intended for lossless compression only, as there are many good lossy formats already, such as Vorbis, MPC, and MP3 (see LAME for an excellent open-source implementation).
* SDMI compliant, et cetera. There is no intention to support any methods of copy protection, which are, for all practical purposes, a complete waste of bits. (...)
Le dernier point est sans appel et sans commentaire.
