Information about the .mp3 (mp3) file type

Below is all the information we have available on file about the .mp3 (mp3) file type.

MPEG Audio Layer 3 file. A .mp3 file is a popular audio format. It contains compressed audio (so is much smaller than an uncompressed equivalent - cf .wav). A .mp3 file contains bit mono or stereo audio, typically at 8, 16 or 24 bit.

.mp3 files are compressed using a lossy compression technique (cf .wav), so there may be some loss of quality when a audio file is converted to .mp3. In practise any loss in quality is not normally noticable, but can result in a loss in quality if a .mp3 file needs to be resampled at a lower bit rate.

Where this is available we would like to include file format information on .mp3 files, as well as information on how to view or open files of type .mp3. If you know of any information which we have missed then please let us know.
