MP2 (MPEG Audio Layer 2) is a Moving Picture Experts Group audio format that comes with a .mp2 filename extension. Like MP3, MP2 is a lossy format and is mostly used for sound broadcasting. Because a limited number of audio players support MP2, it’s best to convert it to MP3, which is a universal format.
AVI (Audio Video Interleave) is a digital multimedia container format developed by Microsoft in 1992 for its Video for Windows project. This file format saves both video and audio data in its container that supports synchronous audio-with-video playback. And like DVD format, AVI allows multiple audio and video streaming as well.
