Recording companies, | however, compensate for this and work to make the sound output from a CD | player as ideal as possible, About FLAC it's actually really interesting. They do a lossy compression action like most other codecs, but they then decode it and compute an additional "error channel", the difference between what the lossy decoder gives and the original it still has access to at encode time. The error channel is compressed in the gzip type sense and added into the FLAC file along with the lossy encode. The end user FLAC decoder does the lossy decompression and then adds on the error channel to give a lossless result in the end. (Sorry Arne... but it's kind of on-topic you know with the Android image getting recooked for this). - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkkv0s8ACgkQOjLpvpq7dMqLigCeLIEmWJieYNQk6nAGyJawaZSj W50Ani6oPQ0GRWNDkMrHxNjADBvipEjC =7g1J -----END PGP SIGNATURE----- _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
