What Is M4A
M4A (MPEG-4 Audio) is an audio format from Apple that can store songs, audiobooks, and podcasts. You can find the audio files downloaded from Apple’s iTunes Store in M4A format.
Generally, the M4A format uses 2 codecs, including AAC (Advanced Audio Coding) and ALAC (Apple Lossless Audio Codec). If the audio file downloaded from the iTunes Store has copy protection, the file will be saved with the M4P extension.
What Is FLAC
FLAC (Free Lossless Audio Codec) is an audio coding format that uses lossless compression. There is no sound quality lost during the compression compared with other lossy audio formats like MP3 and WMA. What’s more, FLAC is an open format with royalty-free licensing.

Sound Quality and Size
FLAC is a good choice if you want to preserve the original audio quality. Usually, the M4A audio downloaded from the iTunes Store is encoded with the AAC codec. AAC is a compressed codec that will lower the audio quality to get a smaller file size. If the M4A audio is encoded with FLAC, it will have good sound quality. Compared with M4A, FLAC files are larger in file size.
DRM Protection
Both formats are generally DRM-free, but M4A has more exceptions depending on where the file comes from.
FLAC is known as an open audio format with royalty-free licensing. Also, M4A has no DRM protection. One thing you need to pay attention to is that the audio with copy protection will use the M4P extension.
Compatibility
M4A performs better in everyday playback compatibility across devices. This format can be played on various audio players and is supported by many operating systems, such as Windows, Mac, Linux, Android, and iOS. While you can also play FLAC on many audio players, its compatibility is not as good as M4A.
