MP3 files are the most widely-used audio file for consumers. MPEG-1 Audio Layer III or MPEG-2 Audio Layer III (MP3) is a digital, audio-coding format used to compress a sound sequence into a very small file to enable digital storage and transmission. If nothing else works, then try VLC media player.ĭeveloped by: Motion Picture Experts Group (MPEG) In this case, download a MPEG-2 video decoder (DVD decoder pack). Sometimes, opening an MPEG file requires the use of third-party software, such as when an MPEG-2 video is part of the file. It can stream over the Internet or play on a hardware player.
