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.
