FFT Plot App Reviews

Works great, helps with visualizing a room to adjust EQ. Very useful.

Does what it says and does it well!

I think I bought the wrong app. Would have likes to be able to expand (zoom) a frequency region of interest. Would have liked to be able to zoom vertical scale as well. No help screen to explain what such things as "mixed" display means.

Simple and clear functionality. My only gripe is the - (negative) scale for SPLs

Very nice, love the window function and controllable # of samples. Used it to check the vibration frequencies of a glass plate. Wish I could email or otherwise share/save the plot, though!

The total DB needs a function to change the weighting A, B or C.

This is a perfectly designed app! The single window interface is sooooo nice. I love that there arent a bunch of "pop up" windows and other clutter. They keep it straight to the point - give you exactly what you need to analyze whatever sounds are around you. The "peak frequency" section is so handy and its great that it shows you the corresponding "note value" right next to it. The pause button is great to just freeze the waveform and analyze the peaks/nulls by sliding your finger across the screen. I have used frequency analyzers in the past on my computer but there was always about 15 steps involved in getting it set up. This app is instant and there is no setup required. I WONT be using the one on my computer anymore and I WILL be buying more apps from this company! If you want a beautifully designed and handy frequency analyzer app - this app is PERFECT! :)

This app seems a bit harder to navigate than others Ive tried -

Rta lite both stopped working and added adds to the last update so I went looking for a new simple app to ring monitors with...this one is doing all it needs to do. Not fancy but totally functional. Heres o hoping hey keep up with it;)

I am using it in a project to analyze and make ocarinas. It is proving very powerful at providing information on harmonic content of each of the fingerings as well as reliable at locking onto the fundamental and displaying it. Very useful also is its settings for integration time since the ocarina is a mouth blown instrument and tone changes a lot with how you blow a particular note. True one can think of lots of features you might want to see added, but for the price you get a powerful tool worth every cent of the price.

This app is awesome!! So much power for fine tuning your sound!! We use it at our practice and at gigs to get any and all feedback, howling etc out of the mix. You can see exactly where the problem is. Easy to use too!

Me and my friend used this app for a science fair project testing the sound waves blah blah blah. Basically it was great and very helpful so thank you and I totally suggest the app for future people interested in getting it.

Displays a clear and accurate the frequency present in an environment. Hats off to the developers A+ app.

I use this program for mode tuning on violins. It an amazing app!!!

Very helpful at analyzing a room and discovering resonate frequencies, hot spots, and dead spots.

Worst app on sound that I ever used...Dont worth the money I have spent on it... It look like a you and NOT a tool that I thought I could use for quick analysis of NVH application. You people are f...up, you dont allow any right comments that is against your apps...

I use it to help EQ vocals and instruments on our churchs soundboard. It compares favorably with a pro sound app on a Mac with a mic. Hey, can you create sound meter app that will compensate for each phone models mic frequency response? I have not found any accurate meter apps.

I have been waiting to have this kind of app! Thanks!

Useful and a needed tool in my audio work. Highly recommend this AP.

Please make the frequency axis fully scalable. Better yet, make it so you can zoom or set to a specific range.
