What is an MP2 file?

MP2 (MPEG-1 Audio Layer II) is the second layer of the MPEG-1 audio coding standard, widely used in digital broadcasting, DAB (Digital Audio Broadcasting), DVB (Digital Video Broadcasting), and early digital audio storage. It offers higher audio quality compared to MP3 but results in larger file sizes. Supported by various players and editors, such as VLC and Audacity. Due to its efficient compression and high-quality audio output, MP2 format remains widely used in professional audio applications.
