Expert Consensus
Most audio engineers recommend M4A (AAC) over MP3 at 128 kbps because it preserves high-frequency detail more effectively. To learn how M4A compares with other audio formats, make sure to read our detailed introduction and review of the M4A file type.
Found an M4A file in your downloads and can’t play it? Here’s what you need to know to learn how to handle audio files saved in such a format. Developed by Apple, these files are renowned for efficiently compressing audio data. Although originally associated with Apple’s platform, it has transcended these boundaries and is now widely adopted across various platforms and devices. In this informative guidepost, we will discuss what M4A is. We will uncover its origins, characteristics, and usage. But there’s more to MPEG-4 Audio files than meets the ear. As a bonus, we’ll delve into software solutions that can play these files and convert them into various formats. Continue your exploration for additional details!
Before we start our exploration, let us first understand the meaning of M4A. Basically, it is a digital audio file format that stands for MPEG-4 Audio. It was originally developed as a successor to the MP3 format and designed to deliver better sound quality at lower bitrates. This format is commonly used for storing compressed audio data.
It provides a high-quality sound experience in a relatively small file size. MPEG-4 audio files are known for their efficient compression. They maintain audio quality while reducing the amount of storage space required. Moreover, M4A is a container file, as it uses the ALAC and AAC codecs. For lossy and more compact file sizes, AAC is the advisable codec. To maximize audio quality, ALAC is the better option.
It is associated with Apple devices and iTunes, as it is Apple’s preferred audio format. These files can contain both compressed audio data and metadata. That includes information about the artist, album, and track. They are versatile and can support various audio codecs. That means they are compatible with various media players and devices.
For a quick rundown of how M4A audio works compared to other formats, we tested how these files compare to WAV. In our test, a 5-minute M4A file was about 30% smaller than a WAV file with no audible quality loss. It also has subpar compatibility issues with older car stereos and low-end devices outside the Apple ecosystem.
To learn how M4A compares to other popular audio formats, we have compared the audio codec, bitrate, and sample rate of commonly used media files.
| Media Format | Audio Codec | Bitrate | Sample Rate |
|---|---|---|---|
| M4A | AAC ALAC |
96 - 320kbps Lossless |
44.1- 96 kHz |
| WAV | PCM | 705–9,216 kbps | 44.1 - 192 kHz |
| M4B | AAC | 32 - 128 kbps | 22.05 - 44.1 kHz |
| FLAC | FLAC | 500–1,500 kbps Lossless |
44.1 - 192 kHz |
| AAC | AAC | 96 - 320 kbps | 44.1 - 96 kHz |

M4A 256 vs MP3 320, which is better?
In terms of audio quality, both files offer high-quality sound. However, the perceived difference may be minimal for the average listener. M4A files at 256 kbps provide a good balance between quality and file size. On the other hand, MP3 at 320 kbps offers slightly higher quality but results in larger file sizes.
What is M4A used for?
M4A is primarily used for storing high-quality audio files. These files can contain compressed audio data using AAC compression. It is used for music streaming, online purchases, and storing audio tracks on Apple devices.
Is M4A video or audio?
M4A is specifically an audio file format. Despite having a format name that includes MPEG-4, M4A is designed to store only audio data. It should not be confused with the M4V format, which is used for video content.
Why won’t my M4A file play in Windows Media Player?
Windows Media Player have no native support for the M4A format. Since it is a built-in Windows tool, the audio format developed by Apple will not be compatible. It is recommended to use a third-party media player to play M4A on Windows desktops.
Is M4A higher quality than MP3 at the same bitrate?
Yes, it is. M4A's better quality over MP3 at the same bitrate is one of its notable advantages. The format is a good option for users who want efficient file storage without sacrificing quality.
Can I just rename .m4a to .mp3 to make it work?
No, it will not work. You need to use format converters to change an M4A into an MP3. Simply renaming the file will not fix the codec, bitrate, and other technical aspects of the audio format.
Which format saves more phone storage: M4A or MP3?
M4A is more efficient and smaller than MP3 files. On top of that, its quality is also better than MP3. However, take note that M4A has subpar compatibility when compared to the MP3 format.
