What is an M4A Audio file?

M4A audio files have the capability to store different types of high-quality audio content— like podcasts, songs, and audiobooks. These files are stored in the MPEG-4 format. Besides, these are encoded either in the Advanced Audio Coding (AAC) codec or the Apple Lossless Audio Codec (ALAC). However, the AAC codec stands out from others like MP3 due to its high-quality audio and compact file sizes.

M4A files are usually based on the ISO-based file format. The MP4 file format is also based on it. Audio and video data may both be stored in this format. The good news is that many media players support this file format. Apple's iTunes, QuickTime, VLC Media Player, and Windows Media Player support M4A files. Additionally, several portable media players support M4A files, including the iPod, iPhone, and iPad.

Harmful Reasons for M4A Audio Corruption

A damaged M4A file might have occurred for a number of different causes. An emerging audio format's incompatibility with established software is to be expected. The following are common causes of damaged M4A audio files:

  • When copied from the original source, the file becomes corrupted.
  • Transferring the file was interrupted for some reason.
  • It was infected by a virus.
  • If you get a call while recording audio in M4A format, the file may become corrupted.
  • The software that records sometimes freezes or quits working.
  • File format not properly synchronized.
  • As a result of SHAREit or any other program failing to completely transmit an M4A file.
