The MP3 file format revolutionized music distribution in the late
1990s, when file-swapping services and the first portable MP3 players
made their debut. MP3, or MPEG Audio Layer III, is one method for
compressing audio files. MPEG is the acronym for Moving Picture Experts
Group, a group that has developed compression systems for video data,
including that for DVD movies, HDTV broadcasts and digital satellite
systems.
Using the MP3 compression system reduces the number of bytes in a song, while retaining sound that is near CD-quality. Anytime you compress a song, you will lose some of its quality, which is the trade-off for the ability to carry more music files in a smaller storage system.
Although MP3 is perhaps the most well-known file format, there are other file formats that can be played on MP3 players. While most MP3 players can support multiple formats, not all players support the same formats. Here are a few of the file formats that can be played on different players:
