What is a MP3? MP3 stands for MPEG 1 (Motion Picture
Experts Group) Layer 3. The power of MP3 files lies in their ability
to store music and audio using substantially less memory than
other formats. Smaller file sizes translate to faster downloads
and less expensive storage requirements, making it possible to
store and play MP3s with reasonable priced hardware. All of this
amounts to a more flexible and affordable way of distributing,
managing and listening to music.
MP3 bitrates are the most important factor in determining
MP3 encoding, (compression), quality, final file size, encoding
speed and MP3 player compatibility.
