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
