good stuff

heard about it from chris on his rift amps youtube channel.

easy to use great for showing you what your ears are hearing

Disappointing

Scale ranges can’t be customized and cannot see low frequencies below 20Hz and DC value. If this were fairly clarified, which it isn’t, I would not have purchased this as it is really useless when those features are what you need.

Great job

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!

Review From an EE in Signal Processing: Excellent!

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.

Absolutely fabulous

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.
