Simplified loop for doing calculations from microphone samples
Simplified loop for doing calculations from microphone samples

In the benchmarks, the correlation can be done in 0.5ms. I'm only
expecting new samples from the microphone every 23ms at best. I don't
need to worry about dropping frames at this point.
