MP3
A file extension and compression method that utilizes the MPEG (Moving Picture Experts Group) standard to reduce the size, often by a factor of 12, while still maintaining audio quality comparable to a CD (compact disc). MP3 files store a song or whole CD and require little hard drive space. Because of their small file size, a computer can save several hundred or thousands of songs.
MP3 was featured as a top term of 1998.
