It's not exactly "raw", as there are ECC (Error Correction Code) data and subchannels that go with the audio, but it's more "raw" than non-audio data (which has extra error correction codes and headers). > When I play a cd with say xmms, xmms seems to be > able to extract the band/album/song data from the cd. Where/how is this > stored on the cd? It's not stored on the CD. Xmms computes a CDDB ID (using the number of tracks, their length and some other information) that is supposed to identify the CD. It then queries a CDDB database on the internet to get the band/album/track information.
