    Mp3 is already compressed, as is the MP2 CDs use.

    If it wasn’t conpressed, you’d be looking at CDs per track, instead of tracks per CD.

      What are you on about? CD-DA, aka audio CD, aka red book audio, is uncompressed 16-bit PCM sampled at 44100Hz. It is lossless.

      MP3 (MPEG-1/2 Audio Layer III) is a lossy encoding standard commonly used for online audio distribution and steaming. MP2 usually refers to MPEG-1 Audio Layer 2, which was most commonly used in Digital Audio Broadcast.

      Neither are used in ‘regular’ CD audio.
