MP3s (the most widely known of compressed audio data storage) are a form of recording that takes the raw data and reduces the quality, allowing the audio to be compressed to a size more easily stored on computers and audio players. The waveform of an MP3 is converted into an audio signalMP3 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". The files recorded in this format are saved with the .mp3 filename extension.
