Yes, all of this will get done for you

But the .m4a container needs to be actually created and placed
around the aac contents.
AudioFileWritePackets won't do that, am I right?
Thanks for your help,

Using the AudioFileReadPackets call you can read the AAC packets
from an ADTS file. Using AudioFileWritePackets you can write them
to an M4A file.
So, its easy to write an audio file duplication tool by just
opening an existing file, creating a new file with the same data
format, then read/write the packets of audio data and the magic
cookie, to the new file.

Hi,
What is the easiest way to wrap a raw .aac file into a
regular .m4a container ?
Can I do that using Core Audio or is there another framework I
should use (QTKit ?) ?
Thanks,
Thomas
