RTA Audio Analyzer Customer Insights

1. So there's your beta testing for you lose the suggestion to download your NG ! Option two make NG compatible with 9 and up !This apps ok great for RTA analyzer..the only thing that i think is this apps will better if we can load the calibration file for the calibrated microphone.Quite happy with it.

2. I have sent them the play store receipt but the developer doesn't reply.Useless without buying pro... only covers half the spectrum with no alteration... its a light show and nothing elseI'd give five if you could set colour to green/yellow/red.

3. Best spectrum you can get otherwise I reckon 馃憤That's what it's designed to do this is not an alignment tool just a basic frequency readerSays it doesn't work properly with most recent android update.

4. Out of all the RTA (well not really but) apps available this is the only one that can come close to displaying what is being played but the levels needed to calibrate speakers is far beyond any phone mic's capabilities.

5. It's just recording distortion + limited frequency response at high and low extremes make these apps worthless for any real use in the audio world.

6. Accurate and useful tool, thank you to the developers!I have paid and downloaded the pro version and then I changed phones but lost my pro version.

7. Even the pro beta version suggests I get your noise generator, which only works with Android9 and under.

8. None can be used for the intended purpose your results will be awfulSomehow I became a beta tester.

9. I wish for an option to use normal basic colours without "3d" shading.

10. Looks like winXP screensaver.I use this app to troubleshoot problem frequencies when I'm mixing in a new room.

11. I don't mind, but? Well I bought the original RTA, now it's the beta RTA.
