This app does exactly what it claims to and looks great. I’ll be using it in the classroom soon to demonstrate concepts like “narrow sound frequency band”. Thanks!

I’m a BSEE (University of Washington, 1995) with experience and a bunch of patents in signal processing. This app is an outstanding tool for understanding the spectral content of an audio signal. It was clearly designed by someone with some expertise in the field, and it’s a joy to use.

Works perfectly. My only wish would be to also look at the waveform in the time domain. I use this app for testing new speakers. You will not be disappointed.
