What is M4A? What is MP3? What are the differences between M4A and MP3? And do you know how to convert M4A to MP3 or MP3 to M4A? If you want to get the answers to the above questions, you can read this post about M4A vs MP3 from MiniTool.

There are three categories of audio file formats - uncompressed audio formats (such as WAV); lossless compressed audio formats (such as FLAC, ALAC); lossy compression formats (such as MP3, AAC). Maybe you are confused with some common audio formats, such as M4A and MP3 audio.

First, let’s see the basic information about M4A and MP3.

What Is M4A

What is M4A? M4A format is a file that only supports audio. It is not an official MPEG-4 file, so it cannot support video. Apple widely uses M4A format for unprotected iTunes music. DRM-protected iTunes music uses an M4P extension. Audio within the m4a file extension is usually encoded using AAC lossy compression, although lossless ALAC can also be used.

Since it compresses with lossless quality, it can provide high-quality small files for you. Besides, you just need to rename the file extension from M4A to M4R, you can directly set M4A audio as iPhone ringtone.

However, M4A has poor compatibility. M4A is developed by Apple Inc., mainly used in iTunes, iPod as well as other Apple devices, and cannot be widely played on many other popular devices.

What Is MP3

What is MP3? The file format was created by MPEG programmers. It is a digital format for the storage of audio files. As one of the most needed codecs for digital encoding, it is widely used in various file-sharing sites to evaluate downloads.

CD tracks can be compressed to 1/10 of their original size while maintaining high playback quality with MP3 format. MP3 is compatible with all the most popular operating systems and is supported by most modern DVD players and music systems.

Before the introduction of MP3, MPEG-1 has been widely used. This format contains not only audio data but also images. MP3 divides the audio file into parts of the same length. After processing, each part is packed in its frame.

M4A VS MP3

Now, let’s see information on M4A vs MP3 from different aspects.

M4A VS MP3: Quality

First, I will introduce MP3 vs M4A quality. M4A is generally regarded as the successor to MP3. M4A files with ALAC codec have the best original sound quality. For M4A audio encoded with AAC lossy compression, it provides higher sound quality and transparency than MP3 files encoded at the same bit rate, especially for bit rates of 128 Kbps or lower.

M4A VS MP3: Compatibility

Then, let’s see M4A vs MP3 compatibility. Compatibility is the rate at which something merges with another. M4A is a limited audio format file. As a result, some devices do not support this feature and do not support sharing on other devices. For MP3, it is highly compatible with other devices.

M4A VS MP3: File Size

M4A can compress audio at the same bitrate in smaller file sizes. The stereo bitrate of M4A format files is usually 128kbps, 192 kbps, or 256kbps. The file size is related to the bitrate. The larger the bitrate, the larger the file size and the better the sound quality.

If you want to get the same sound quality, you need a bitrate of 256kbps when using MP3 encoding, and only a bitrate of 192kbps when using M4A. That is to say, you will get a smaller audio file size with M4A.

M4A VS MP3: Industry Support

The next aspect of MP3 vs M4A is the industry support. Since the 1990s, MP3 has been the de facto standard for digital music files. Almost every computer media player can recognize and play MP3 files, making it very popular to download and exchange music with others.

However, overall, industry support for M4A and MPEG-4 is growing. Most audio/video players that can play MPEG-4 files will recognize M4A audio files. In short, M4A keeps up with the trend.

M4A VS MP3: Pros and Cons

The following are two forms about the M4A vs MP3: pros and cons.

M4A: Pros and Cons

Pros  Cons
Easy to distribute audio on the internet without worrying about protecting it. Doesn't support Digital Rights Management.
Can be directly set as an iPhone ringtone. Not widely supported except for Apple devices, and players like VLC.
Better audio quality at a smaller size

MP3: Pros and Cons

Pros Cons
You can increase quality by increase the bitrate, but it also increases the size. Not all MP3 files are of high quality.
Compared with the CD format, the file size is significantly smaller, so it is easy to stream. It resulted in music piracy since it can remove specific audio.
Portable Media Player become a possibility because of this. It is not comparable to CDDA or other uncompressed formats.

Which One to Choose

Just now, you have known the differences between M4A and MP3. Now, you may wonder which one you should choose.

On the one hand, if you are an Apple fan, you may prefer M4A files, then you should choose M4A. If you want to play audio on Android Samsung, HTC, and other devices, you may need to choose MP3.

On the other hand, if you are worried about sound quality, please consider choosing M4A. However, if you are mainly concerned about compatibility, please choose MP3.

Now, let’s see how to convert M4A to MP3 or MP3 to MAR.

M4A vs MP3 FAQ

Why can't I play M4A files?
The player will wait until the M4A file is fully downloaded because of encoding issues, then it starts to play. Thus, sometimes, you can’t play M4A files. If you want to play the media file immediately, you can convert it to an MP3 file to play.
Are M4A and AAC the same?
No, they are not the same. M4A files typically contain audio-only and are formatted as MPEG-4 Part 14 files. AAC is not a container format, but a raw MPEG-4 Part 3 bitstream with an encoded audio stream.
How do I reduce the M4A file size?
You can customize audio quality to reduce M4A file size. You can also change the audio format to a smaller one such as MP3 to reduce the size.
Which is better quality MP3 or AAC?
