Ratings and Reviews
I really like this app!
I used it to diagnose a whistle sound in an air handling unit. It works quite well and I have told several other people about it. I use an iPhone 5 and when you take a screen shot and upload it to your computer, it looks very professional.
The other features are very nice, too. My only suggestion is to allow zooming in on the Hertz scale.
I use this app when I'm performing the final tuning in car audio systems and I'm impressed with the response and resolution it has. It could be better if it supported external microphones such as ZOOM's XY and omni capsules but performs pretty reliably through the iPhone's internal microphone. And fairly accurate up against my ARC software in my recording studio studio. Well worth the money if you need a good FFT
Favorite fee app
As a studio engineer who has to run live sound a few times a year, this app saves me a lot of trouble. I can ring out mics in a heartbeat and solve problems more quickly on the fly. No more sweeping for the exact frequency to notch, or for where to center the de-esser! It’s especially handy on an iPad with its larger display.
With Family Sharing set up, up to six family members can use this app.
