MP2 also known as Musicam is a short form of MPEG Audio Layer 2, and it is also used as a file extension for files containing audio data of this type. While it has largely been superseded by MP3 for PC and Internet applications, it remains a dominant standard for audio broadcasting as part of the DAB digital radio and DVB digital television standards.
