What is M4A?

M4A, developed by Apple, is a file extension used for MPEG-4 Audio files. Although M4A files are similar to MP3 files, they typically offer higher audio quality with a smaller file size. They are commonly used for music downloads and streaming. M4A files can be encoded with different audio codecs, such as AAC (Advanced AudioCoding), ALAC (Apple Lossless Audio Codec) or MP3 (MPEG-1 Audio Layer 3). AAC is the most common codec used for M4A files, as it provides high-quality sound and is supported by a wide range of devices and platforms.

You have the following tools to play an M4A file:
  • Media Players: Windows Media Player (Windows), iTunes (Mac), VLC Media Player (Windows/Mac/Linux), etc.

  • Audio Editing Software: WorkinTool VidClipper (Windows) Audacity (Windows/Mac/Linux), Adobe Audition (Windows/Mac), FL Studio (Windows/Mac) and more.

MP3 or M4A, which one is better?

Features MP3 M4A Conclusion Winner
Quality MP3 adopts a lossy algorithm, so it does not share the same good quality as M4A. However, as it is small in size with feasible sound quality, it is still a universal audio format for online music streaming and social media use. M4A is a lossless format (encoding algorithm) for the apple platform to share digital music, audiobook content, and podcasts. It is believed to be the successor to MP3 because the file quality is better than MP3 files. M4A also sounds better than MP3 files if encoded at the same bit rate due to some enhancements. M4A
File Size For MP3, it uses perceptual coding. So, basically, it will remove undetected information by ear. M4A is now encoded with advanced AAC audio coding and equipped with the best compression standards and ALAC (Apple Lossless Audio Codec) specifications. The M4A file is much smaller compared to the MP3 of the same content. M4A
Compatibility MP3 is a universal audio format compatible with all platforms (Windows, Mac, Android and iOS) and all devices (Computers, smartphones, tablets, digital music players, etc.). M4A is developed by Apple to play audio files. Now you can open M4A files in the most well-known audio-playback programs. Not only for Apple products, but it is also already the default audio format for Android, Nintendo, PlayStation products, and many in-car music playback systems. Overall, in terms of compatibility, it has begun to take the place of MP3. M4A
