RTA Pro Analyzer

BAR NONE. ONE OF THE BEST TOP 10 Purchases of software in my life! Sure it looks a bit Simple. But this app is PRO all the way. It still has some slow downs. But I think its one of the most accurate out there when used with a calibrated microphone. And the App is just cool. I have it on in the background. And in the tv in my van. I think this may have been one of my First app Purchases. Money very well spent!

Works well. Has the basic FFT functions, but doesn't include signal generation. My only beefs are that the peak hold line is so thin that it's nearly invisible; there's only a bar display mode, no line mode; and no way to load a mic cal on top of the internal circuitry cal.

Hmmmmmm tring to measure the peak noise level, when ever i press the start button i always get a sharp peak which is useless as soon as you start, the background noise was measuring about -70 dbfs but the peak at the start saw spiking at anything from between -50 & -8 yet there was no noise present, so it renders the peak level detection useless.

Nice enough app. New calibration crashes Samsung S10. Interestingly the free version didn't. Hoping for an update that will correct the issue.

Great app. Really wish someone would make possible to view 2 traces from 2 sources i.e front speaker and external inputted source via the trrs mic input. So you could measure the output of your console vs speaker reference like smaart.

Works ok with standard calibration however the app crashes once it hears pink noise during a new calibration. Used on Galaxy S10+. If that issue can be fixed it would be a 5 star review

This is as PRO as my little pinky. There's no option to load up a calibration file and manual calibration is really bad... I had to refund this app after trying it out.

Pro version cats miau. Amazing how much background noise there is. Trying to match curtains to filter out car noise.♡♡♡

Interfered with my LG thinq g7 - kept the fingerprint scanner from working properly. Cant load calibration files for attached microphones.

Overall is good, but I want to try the calibration the of band . But How to calibrate for each number of band frequensy?

The radon soft site no longer exists. So this software is what it is and it's not going anywhere else.

Needs more frequency labelling on bandwidth. And needs option to recieve input from headphone jack

Love this app! Dont know why it took me this long to by it! keep up the good work.

Calibration Crashes Galaxy S5, so pretty much useless.

I paid for the app but its not getting downloaded .. past 1 week..

Works really well with just the Mic from phone it tablet

keeps crashing when doing calibration

Less than zero. Busted. Refunded.

This paid version allows u to calibrate your phones mic with pink this making the rta info actually useful. And u can get to 1/6 and 1/12 modes with the pay version...those 2 reasons are worth more than $5 imo. Been running it side by side with Smaart 7 on a thinkpad with a KT analyser mic and $900 usb pre....the smart display and the calibrated phone display read IDENTICAL from 60hz to 10k. The phone rolls out kwik below 60 and above 10k. So smaart does have the advantage there. $5000 vs phone + $5. :)

Seems to work great, but only half the time that I can get it to even start up on my S4.

It works very well. Does what I need it to do. The only fault I have with it is that the icon somewhat resembles a pile of poo.

Simple, solid and ready for work. I've been a professional audio engineer for nearly a decade and this little app still impresses me.

I like the app but it crashes when you play pink noise through it during new calibration. Please fix it.

The app crashes upon starting a new calibration. Without mic calibration this app becomes worthless. I'm using a Samsung S5

Been testing a few these apps, this one has to be the most useful of them all and im still looking to better this one but yet to find a better app.

So far is really handy this app. I do live sound and it works just fine ..
