FFT Plot App Reviews

Perfectly does its job. Thats it.

a big button, constantly on the screen, just to bug people to review the app is something i can not accept in paid software. works well though.

Very useful tool.

Very cool app that tells you the spl at different frequencies.

This is an awesome app. Fastest and highest resolution FFT I have seen on App Store. Professional development and works well. My only request is that there be a better measurement system of overall volume ("60dB" for voice and "95dB" for concert, etc.) Oh! Also, please add split screen support for iPad!

I use this app when Im performing the final tuning in car audio systems and Im impressed with the response and resolution it has. It could be better if it supported external microphones such as ZOOMs XY and omni capsules but performs pretty reliably through the iPhones 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

This app is great for finding noise sources. I have been using it now for a good while and have been very pleased with it. It is easy enough to use and it wasnt expensive. I hope you enjoy it too!

I use this at FOH a lot and really love it! Very useful and accurate!

Nice, simple app. It does the job well. I downloaded this app to test the frequencies in songs, as I curious what are the notes sung.

Its fast/slow and window choices, and look and feel are very natural for working in the frequency domain. Watching music it just "looks" proper. The ability to decode the frequency peak to a musical note is a natural, but extremely useful feature... Three features Id like to see? 1) Screen capture video... share the look of your favorites dynamically. 2) Capture-Process-Slomo: capture a length of audio, process the FFT, then play the video back slowly, with scrubbing, to allow transposition of complex arpeggios... 3) Transpose 2) into musical score or tablature.

I use this for music instruments and tuning forks. Does the job.

Would be perfect if it can record a samples

Easy to use.

Ok, nice and useful, But Display flickers when Audio Play-back is Running. It only analzye the Input of Mic and LR Input. I Need to Analyze a local Audio file , how?

Flawless FFT analyzer. Highly recommended.

With out tone generator limits the use of this. Also a bar graph would help when setting EQs

Im gonna use this for testing the sounds of crystal bowls to buy.

App is good for mapping SPF. A help section for application for this app would be cool

A calibration utility would be helpful. Seems to read low frequencies incorrectly on iPad mini.

A good app. that has great potential but needs some instructions and advice to get the most out of it.
