By the way, your code raises another question. Is PCM data itself the array

through each frame of a PCM file and extract the
kAudioQueueProperty_CurrentLevelMeter property into a new array?

Depends how you extract the PCM data. What is your source file format?

Actually, what I'm working on now is a closed system, so the format can be anything I want. I've been using CBR .wav PCM files for testing. Is there a more efficient format to use as my standard?
