MP3
From WWR
MP3 (MPEG-1 Audio Layer 3) is a digital audio encoding and lossy compression format invented and standardized in 1991 by a team of engineers directed by the Fraunhofer Society in Germany. It was designed to greatly reduce the amount of data required to represent audio, yet still sound like a faithful reproduction of the original uncompressed audio to most listeners. In popular usage, MP3 also refers to files of sound or music recordings stored in the MP3 format on computers.
