Re: Problem with AAC and AudioFile

If I create an AudioStreamBasicDescription with a FormatID kAudioFormatMPEG4AAC, how do I deliver my data to CoreAudio? Can I just open an m4a file and feed in the raw contents of the file?

Thanks oodles again,

------ ORIGINAL MESSAGE ------

The AudioFile API supports the ADTS file - this is an MPEG2 defined bit stream, but it is not MPEG-4.

QT can make mp4 files, and the iTune's m4a files are essentially MPEG-4 files that have just audio data in them.

At this stage there's no direct bridge between these two bit streams, but this will be addressed at some point
