M4A VS MP4:Why Do You Convert M4A to MP4

M4A stands for MPEG 4 Audio. It is often found in Apple's iTunes Store as the format of song downloads. Most programs support the playback of M4A files, including iTunes, QuickTime, Windows Media Player, and more. Compared with MP3, the M4A file is better in quality and smaller in file size. As a result, M4A files sound better than MP3 files when encoded at the same bit rate.

But sometimes, you may want to convert your M4A audio to a video format - MP4. MP4 files are used with multiple stations and video players simultaneously, and they can store video, audio, and other suitable amounts of data subtitle even. It is a widespread file format due to its container format, and it is also used with multiple platforms such as iTunes, PlayStation, and portable PSP.
