What is MP3?
MP3 format, short for MPEG-1 Audio Layer 3, a revolutionary digital audio format, is developed by Fraunhofer-Gesellschaft and Thompson Multimedia in the late 1980s and brought to the mainstream through the Internet in 1997. It is a common audio format for consumer audio storage, as well as a standard encoding for the transfer and playback of music on digital audio players. MP3 is a near-CD quality file format for sound files and is very popular for music on the web. As an audio-specific format, MP3 becomes more popular when people use it to swap music online because of its powerful compression.
MP3 is a non-proprietary format that can be played with a whole host of different players. For users who have large music collections, it is a good choice to backup and enjoy.
