The MP3 audio format uses the MPEG-1 or MPEG-2 encoded audio, which is then encoded using a lossy compression technique to reduce the file size by 50–60% depending on the quality chosen and the encoder's settings. MP3 files usually have a bitrate between 128–320 kbps and average duration of 4-8 minutes per track.
