AMR was adopted as the standard speech codec by 3GPP in October 1999 and is now widely used in GSM and UMTS. | MPEG-4 Part 14 or MP4 is a digital multimedia format most commonly used to store video and audio and store other data such as subtitles and still images. Like most modern container formats, it allows streaming over the Internet. |
| Technical details | AMR speech codec consists of a multi-rate narrowband speech codec that encodes narrowband (200-3400 Hz) signals at variable bit rates ranging from 4.75 to 12.2 kbit/s with toll quality speech starting at 7.4 kbit/s. Sampling frequency 8 kHz/13-bit (160 samples for 20 ms frames), filtered to 200-3400 Hz. | Most kinds of data can be embedded in MPEG-4 Part 14 files through private streams. A separate hint track is used to include streaming information in the file. |

If you think about it, just a decade or so ago, file formats were really important. People were discussing the differences between various file compressions and you often had to install an app extension if you wanted it to run a certain file format.
It seems that everything changed with the iPhone gaining mainstream popularity. Since all files were now hosted within apps, we never came across any incompatibility issues. Similarly, with more of our work moving to the web, it’s stored within appropriate software right away, so we don’t have to deal with file formats.
Still, occasionally, you might encounter a file that you can’t open or that you’d like to convert an audio file to another format. One of the most frequent issues for Mac users, for example, is dealing with M4A files, which you often want to convert to MP3s. So let’s discuss briefly what is M4A format and where you can find the best M4A to MP3 converter today.

What Is M4A And How To Use It
You might be more familiar with M4A files if you think of them as MP4s, which they essentially are — the only difference is that an MP4 file can handle video while .m4a is for audio only.
MP4 (also known as MPEG-4) is in turn based on QuickTime File Format (QTFF) and, in some sense, was developed to replace MP3. M4A files, for example, are generally smaller in size and can store audio in better quality than MP3s. Their only downside is that M4A players are much harder to find, whereas MP3 is one of the most universal audio formats out there.
So where can you stumble upon the .m4a format? Mostly in Apple’s own iTunes Store, as it’s the default file extension for song downloads, which is then encoded with AAC for reduced file size or ALAC for lossless audio. However, copyrighted songs might also come in the .m4p format, which is a variant of .m4a.
All this leads us to the question of how do you play M4A vs MP3 on Mac and what’s the easiest way to convert file to MP3?
How to play M4A files on Mac
As already mentioned above, a lot of the M4A files you’d come across are from the iTunes Store, so naturally you’d be able to play them on iTunes as well (or the Music app from macOS Catalina onward). You can drag and drop any M4A file into Music and it’ll be added to your library.
In addition to Music, or iTunes, M4A files also work with QuickTime Player (since they are based on QuickTime File Format), which is one of the default apps you can find in your Applications folder. While QuickTime is mostly used for playing movies, it has a standard audio playback functionality built into it as well. But what if you’re after a great .m4a audio experience?
Play M4A on Mac
With Elmedia Player, you don’t have to convert your M4A file to other formats. Just hit the play button.
Elmedia Player is one of the most versatile audio and video players out there.

How to convert M4A to MP3 using iTunes
While there are quite a few M4A players available on Mac, whether via default or third-party apps, you might often need to convert M4A to MP3 iTunes format to make it more widely available — so you can easily port music or audiobooks to virtually any device.

Surprisingly, there’s a way to use iTunes as an audio file converter, although not many people know about it, since it’s not that straightforward. Regardless, here’s how you can convert file to MP3 using iTunes:
Launch iTunes (or the new Music app)
Open Preferences (⌘ + ,)
Navigate to Files ➙ Import Settings…
Change Import Using to MP3 Encoder ➙ OK
Drag and drop your M4A file into iTunes
Select it and then go File ➙ Convert ➙ Create MP3 Version
Find the new file created in your library (the old file will still be intact)
In a similar fashion, you can change the default iTunes encoder to create WAV, lossless, AIFF, and AAC files. Overall, iTunes is a good enough M4A converter and general file converter to MP3 if you only need to convert one or two songs occasionally. For more regular conversions, there are much more efficient apps out there.
