Pretty great! Could have better decibel calibration

This is an awesome app. Fastest and highest resolution FFT I have seen on App Store. Professional development and works well. My only request is that there be a better measurement system of overall volume ("60dB" for voice and "95dB" for concert, etc.)

Oh! Also, please add split screen support for iPad!
