| Hi Samuel,
If an audio queue offers level metering then that would be fine (although I also need to provide levels when I'm not actually recording which may exclude this option). However, ideally I'd like to know why this isn't working and how to solve it because it seems like it should be possible.
I'll have a look into the audio queue alternative but if anyone has any ideas I'd be most grateful.
Simon

I think that I have it all set up properly but I only ever get -120.0 returned as the decibel value of the kMultiChannelMixerParam_PreAveragePower parameter of the mixer.
