How to Convert M4A to MP3 Audio File (Mac & PC)

M4A is an audio file extension natively used as Apple audio format used in iTunes Store and outdated iPods. It is based on MPEG-4 technology and is actually the audio layer of MPEG-4 video. The songs you stream on iTunes Store with iOS player (iPhone, iPad) are in .m4a format, these songs are encoded using advanced audio coding (AAC), a lossy compression codec that will encode file in less storage space but higher quality than MP3 file. For Mac users, there will be no any issue when it comes to playing M4A audio files.

However, as the successor to MP3 intended, M4A don't get expected popularity in digital audio distribution. It is somehow limited only to Mac-centric devices and applications. In many cases, you may need to convert M4A to MP3 file, the most well known digital audio format. MP3 is already adopted by music lovers and collectors. The MP3 format is capable of being played on almost any media player, application and handheld device, making it hard for other digital audio compression format including .m4a to replace it.
