MP3

MP3 is a popular digital audio encoding and lossy compression format invented and standardised in 1991 by a team of engineers working in the framework of the ISO/IEC MPEG audio committee under the chairmanship of Professor Hans Musmann (University of Hannover - 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.

The name is derived from "MPEG-1 Audio Layer 3" more formally known as ISO/IEC 11172-3 Layer 3. The files recorded in this format are saved with the .mp3 filename extension. This extension is also sometimes shared by audio files encoded using the newer MPEG-2 Audio Layer 3 standard. The invention of this file extension name (.mp3) would be due to the FhG institute.
