Part 1: What Is M4A – Definition of M4A

M4A is an audio-only MPEG-4 file. The official filename extension of MPEG-4 file is .mp4 which contains both video and audio data. When it only contains audio data, it uses .m4a file extension. M4A format is widely used by Apple for unprotected iTunes music (DRM protected iTunes music uses M4P extension). Audio within the m4a file extension is typically encoded with AAC lossy compression, though lossless ALAC may also be used. Generally speaking, the quality of M4A is better than that of MP3 and its file size is smaller than MP3 file. >> See AAC vs MP3

Part 3: M4A vs MP3: Which Format Is Better?

M4A vs MP3: M4A is typically perceived as the successor to MP3. But compared with MP3, M4A can compress audio with the same bit rate in smaller file size. M4A format files typically have stereo bit rate of 128kbps, 192 kbps or 256kbps. By the way, Bit rate is the amount of data that is conveyed per unit of time.

As for quality, an M4A file with ALAC codec has the best original sound quality. Even M4A (AAC) delivers better quality than MP3 audio at the same bit rate. As for the file size, it is also related to the bit rate. The larger the bit rate, the larger the file size and the better the sound quality. To put it another way, if you try to get the same sound quality, you need 256kbps bit rate when encoding with MP3 while only need 192kbps with M4A. As a result, you'll get a much smaller audio file size with M4A. However, MP3 is still the most popular audio format thanks to its much better compatibility.

It's arbitrary to say that M4A is better than MP3 or vice versa. Choosing which audio format to use still depends on your own needs.
