A file with an MP2 extension is a type of audio file. MP2 was created in the mid-90s after the release of MP1 by the ISO's Moving Picture Experts Group (MPEG) in an attempt to standardize the digital encoding of audio and video files. It has an MPG Layer II compression, but is different from MPEG-2 video files, which use the MPG extension. A smaller compression ratio than MP3 has made MP2 files less popular, although they are still used in digital television and digital radio broadcasts. You can open an MP2 file with RealNetworks RealPlayer Cloud or VideoLAN VLC Media Player (Windows, Mac, or Linux), Apple iTunes or Adobe Audition (Windows or Mac), or Microsoft Windows Media Player or PeonySoft MP2 Converter (Windows).
