Which audio codec are you people using when ripping cd’s? I used wav but the size made it not really fitting on my phone (60GB) I switched to FLAC. Many people I talked to said that CD’s just use mp3 codecs in the First place.
CD Audio came way earlier than mp3… It is CDDA, Compact Disc Digital Audio. For its spec, please give wiki a read. FLAC is a good lossless alternative to WAV. I have most of my collection in FLAC too.
