There is a way around it. What it is though, I don't know. I'm not an expert in FFT by a long stretch!!
I have an app on my old iPhone 3G from eight years ago called Audio Tools that has a very good spectrum analyzer which has the option of running the FFT as equal points per octave and it runs well in real time. That iPhone runs a single core 400MHz processor.
All this is under the assumption that Justin is using FFT for the waveform frequency calculations. That might not even be the case though.
