AVAudioRecorder metering

[kajensen]

Is there a way to use this library to get the meter (really want [mic averagePowerForChannel:0]) of the microphone input?

Hi, I know very little about audio, or this library.

Here is how I am achieving it. I don't know if it is dumb or if there is an easier way, etc...

What I do is i use EZAudioFFT. You can take a look at the sample app that is provided. Essentially, you feed the delegate data from the player or microphone to the FFT. From the FFT delegate you can get
float maxFrequencyMagnitude = [fft maxFrequencyMagnitude];
This may be enough to achieve what you want. Again, it may be overkill or the wrong approach, but it is feasible.
