Creating MP3 Output Files

Compressor provides the tools you need to create exceptional MP3 files.

MP3 is a specific type of MPEG encoding known formally as MPEG audio layer 3. MP3 uses perceptual audio coding and psychoacoustic compression to remove all superfluous information (specifically the redundant and irrelevant parts of a sound signal that the human ear doesn’t hear anyway). The result is that MP3 encoding shrinks the original sound data from a CD (with a data rate of 1411.2 kilobits per one second of stereo music) by a factor of 12 (down to 112–128 kbps) without sacrificing very much sound quality. Proponents of MP3 actually claim there is no sacrifice in sound quality, but audio professionals can usually hear the difference on good equipment.
