Spectrogram #

This is a simple and opinionated spectrogram I made to help mix church audio. See below for technical notes.

The main purpose I made it for is to see intensity of audio in a frequency range, so even though it’s not going to be perfectly calibrated to your device, it should help you locate and squelch feedback.

I set the smoothing time constant and FFT size fine enough so you should be able to see slow falloff of audio energy in a frequency, which you can use to identify resonance in a room.
