Does GetMovieAudioVolumeLevels() support more than two channels of audio?

Question

I have some code that uses GetMovieAudioVolumeLevels() to get levels of a QuickTime movie during playback.

I have an 8 audio channel QuickTime movie, but using the GetMovieAudioVolumeLevels() call it only ever returns 2 channels. I am using kQTAudioMeter_DeviceMix, and right now I'm assuming because my MacPro can only actually playback 2 channels of audio (left and right) QuickTime is mixing the 8 channels down to 2 channels.

Does anyone have any more experience with this?

Thanks.

Answer 1

It appears that "channels are automatically mixed-down as needed (when playing multichannel sound through a stereo output, for example)."

Does SGGetChannelVolume do what you need?
