MP3 Files

MP3 files contain perceptually encoded sound data.


The frequencies that humans cannot perceive are removed, although some audio purists say they can tell the difference between a high bit-rate MP3 and a Wave file.


A typical MP3 is 10 times smaller than an equivalent WAV file.


MP3 files usually end in .mp3. They are also used with .mp1, and .mp2 file extensions.
