What is the easiest way to wrap a raw .aac file into a .m4a container

Question

This question is overflow from the following question:

http://stackoverflow.com/questions/70096/how-do-i-programmatically-convert-mp3-to-an-itunes-playable-aacm4a-file

Anyway, I learned how to create an aac file and then i found out that an aac is not just an m4a file with a different file extension. In fact, I need to somehow wrap the aac into an m4a container. Ideally I'd be able to simply make a call to the command line.

Answer 1

mp4box if you want a dedicated tool; its probably the easiest way to go. ffmpeg can do the job too.

Answer 2

dBpoweramp , a commercial utility can do this. You can also try the free, open source MediaCoder.
