Excellent app

I’m a physicist and I teach acoustics in some of my courses. This app has been really useful for showing my students the frequency components of various sonic disturbances. I’m also a musician and have used it in other contexts as well. It’s a great app and very effective.

Great app, very useful

As a 20-year audio pro, I find this a handy little tool for quick measurements and problem-solving. Love the pause feature and the screenshot export. For live rooms or in the studio, this app is no-nonsense, efficient, and quick.
