Short for MPEG Layer 3, a type of audio data compression that can reduce digital sound files by a 12:1 ratio with virtually no loss in quality.
Stands for "MPEG-1 Audio Layer-3." It's the latest standard for compressing audio files. On average, an MP3 file is about one-twelfth the size of the original audio file. However, the sound is nearly CD-quality. Because of their small size and exceptional sound, MP3s have become extremely popular. In fact, there are many web sites, like
MP3.com and
RioPort.com, containing huge archives of MP3 audio files. To listen to MP3s, you'll need a program like WinAmp (PC) or MacAmp (Mac). To create an MP3 file from a CD, you'll need an encoder program to convert the audio track to an MP3 file. "Is this legal?", you ask. Well, that's a good question. In fact, the issue has yet to be resolved. To get all your MP3 questions answered, check out the
