What is MP4?

What is MP3?
MP3 (MPEG-1 Audio Layer III) is the most popular audio format for music and podcasts. It uses lossy compression to reduce file size while maintaining good audio quality. MP3 files are compatible with virtually all devices and media players, making them the universal choice for audio distribution.
