What is a MP2 file?
MPEG Layer 2 audio used in digital broadcasting
MP2 files were the predecessors to the MP3 file format. MP2 files are primarily used to store audio in a compressed format to reduce the file size. They are usually compressed with the MPEG Audio Layer-2 compression codec. While teh MP2 file format is still used for audio, the MP3 format has become much more common. However, you can still find MP2 files still used for digital radio and digital television broadcasts because the standard MPEG Audio Stream supports 32, 44.1, and 48 kHz sampling rates and bitrates from 32 to 320 kbps/sec.
Common uses for MP2 files
- Digital radio broadcasts
- Digital television audio
- Legacy audio files
- Digital radio recordings
- TV broadcast captures
- Legacy audio archives
Who works with MP2 files?
Broadcast engineers and radio producers work with MP2 daily because it remains a standard audio codec in DAB digital radio and DVB television infrastructure. Journalists and media monitoring teams who capture broadcast feeds, along with archivists digitizing older broadcast libraries, also handle MP2 files regularly.
MP2 vs MP3: which should you use?
MP2 (MPEG Layer II) and MP3 (MPEG Layer III) come from the same MPEG audio standard, but MP3 uses more advanced compression and achieves comparable quality at lower bitrates, which made it the dominant format for music and downloads. MP2 is simpler to encode and decode and more resilient to transmission errors, which is why broadcasters kept it for digital radio and television. Choose MP3 for general distribution and playback compatibility; you will mostly encounter MP2 when working with broadcast feeds or archives.
