MP3 is an audio-specific format that was designed by the Moving Picture Experts Group as part of its MPEG-1 standard. An MP3 file that is created using the mid-range bit rate setting of 128 Kbit/s, which will result in a file that is typically about 1/10th the size of the CD file created from the original audio source. An MP3 file can also be constructed at higher or lower bit rates, with higher or lower resulting quality.
