AVAudioRecorder can record to file with

kAudioFormatMPEG4AAC, however Core Audio docs say AAC is not a supported recording codec:  https://developer.apple.com/library/ios/documentation/MusicAudio/Conceptual/CoreAudioOverview/CoreAudioEssentials/CoreAudioEssentials.html#//apple_ref/doc/uid/TP40003577-CH10-SW26

Does this mean that AVFoundation can do something Core Audio can not?

Confused, looking for explination, thanks!

Nope, just looks like the document needs to be updated. You can submit "Feedback" directly on the documentation page with the the missing information. Note that kAudioFormatMPEG4AAC is from CoreAudioTypes.h giving you an idea of which technologies are built on top of others.

Thanks, Core Audio isn't confusing at all...😕
