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.
