YouTube accepts most audio formats inside video containers. If you're editing in Premiere, DaVinci, or Final Cut, M4A imports without hassle.
YouTube will re-encode your audio regardless. Starting from a 256kbps or higher M4A source gives YouTube's encoder enough headroom to produce clean output.
Background music, voiceovers, sound effects. Convert each to M4A, import into your video editor, and export. AudioUtils makes the conversion step painless.
Frequently Asked Questions
Is M4A better than MP3?
At the same bitrate, M4A (AAC) sounds noticeably better than MP3. AAC is a newer, more efficient codec.
Will M4A play on Android?
Yes. Android has supported M4A/AAC natively since early versions. It's not just an Apple format.
What's the difference between M4A and AAC?
AAC is the codec. M4A is the container (file format). M4A files contain AAC-encoded audio, similar to how MP4 contains video.
Should I convert my whole library to M4A?
Only if you primarily use Apple devices and want marginally better quality. Converting between lossy formats always involves some quality loss, so it's best to convert from lossless sources when possible.

About M4A
Apple's preferred audio format. Better quality than MP3 at same bitrate. Default for iTunes and Apple devices.
