How to Convert M4A to MP3 On a macOS

MP3 is a standard and widely known term used for audio files around the globe. Whenever a digital device user or a smartphone user converses about the MP3 file format, that simply refers to the audio-based files. However, in addition to the MP3 extension, audio files can be stored in various formats such as M4A, AAC, ALAC, DSD, etc.

M4A file format

As cited above, M4A is another extension used for audio files. The Apple users are often more familiar with M4A file format; if you are an iPhone user, you would be aware that M4A is the default file extension used in the iTunes store to download the audio files.

It was basically released for Apple products; that’s why the default media player in Apple devices, i.e., iTunes or Music by the name, can play the M4A files without any format conversion.

M4A vs Mp3

M4A and MP3, both file formats, present audio files in smaller sizes. Despite the high popularity level of MP3 file format, M4A is still better than MP3, given the audio-quality aspect. However, there are only a limited number of media players available that support the M4A formats.

Conversion of Audio file formats

If you have any audio file in a format other than MP3, then that can’t be played on all devices; it is pretty tentative that the media player of the respective device is whether able to play that audio file or not. This is because most media players often tend to play the audio files in MP3 extension only and generally don’t support any other audio format.

To address this challenging state, you might be required to change the audio extension from m4a to mp3 so that it can be played by any media player. This conversion can be carried out either by employing any third-party media conversion app or the built-in media player of the respective device.
