Frequently Asked Questions
What is the difference between AAC and M4A?
AAC is the audio codec. M4A is a file container (MP4/MPEG-4) that wraps AAC audio. M4A = AAC codec + MP4 container. Similar to how MP3 is both a codec and container, but M4A separates them.
Can I rename .m4a to .mp4?
Technically yes — M4A is just MP4 without video. But most apps expect .m4a for audio-only files. The MIME type is audio/mp4 for M4A vs video/mp4 for MP4 video.
