MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a popular digital audio encoding format. It uses a lossy compression algorithm that is designed to greatly reduce the amount of data required to represent the audio recording, yet still sound like a faithful reproduction of the original uncompressed audio to most listeners (above 128kbps). Although people tend to think it's free because it is gratis, MP3 is a proprietary standard that was invented by a team of European engineers of Philips, CCETT, IRT and Fraunhofer Society.
