Can someone please post, in as much detail as possible, which AAC audio profile and bitrate settings Quicktime utilizes during an export on OS X Mavericks (10.9) when choosing File > Export > Audio Only... using a 16-bit 44100 Hz .wav file as a reference
I can observe, using the Inspector window in QuickTime, that the exported files approximate 256kbps (VBR?) and are 48000 Hz, but I want more precise and complete information.
