um - your "doSomething" - that seems like you are trying to write some kind of compressor - metering is not going to really be the right thing for you anyway I think.

Perhaps you could give a broader sketch of what you want to do and we can suggest something

Hi Bill,

Wow, that's a bummer! So what are my options for low latency level metering on the iPhone?

Is is correct that I can expect a full second of latency between the mic level getting hot and a sound file playing when using audio queues? That's been my experience so far, but is there a way to get this any faster? This is a crucial piece of the application I am trying to make.

Do I need to sort out level metering myself? I would love to see an API where I could get low latency metering with something like:

turnMicOn()

if (micLevel >=.7)
{
	doSomething;
}

turnMicOff()

Hi Andrew

My mistake - I was looking at the wrong code on our side.

We don't have metering supported for the iphone mixer at this point. Something we'll look into

Sorry about wasting your time

Bill
