With today's technology improving music and media devices, files must also offer greater quality. Smartphones, tablets, portable music and other media devices are now using the MP4 file format.
The MP4, MPEG-4 Video File, was created by the Motion Picture Experts Group. It compresses audio and video files separately to offer a higher level of sound and picture quality while at a smaller file size. This allows you to save additional space on your devices so you can load more MP4 files. Most devices are using the MP4 encoding and ACC file compression format for better playback of media.
