Hi. I'm a complete newcomer to Core Audio and as such I'm learning a lot and scratching my head in equal measures. I've created a test application which records audio from an input source (and allows the source to be selected) using AUHAL. What I'd like to do next is display the input level of the input device but I'm at a loss as to the best way of doing this so I'm hoping that someone can give me a pointer in the right direction, essentially a rough outline of what I need to set up.
I have a feeling that I may have set off at too low a level and would be better off using an audio queue to do the recording but before I start over I wanted to see if anyone could give me some advice on where I should be focusing my investigations.
This is all being done on OS X 10.6.
Many thanks.
Simon Wolf
