Spectrum RTA Customer Insights

1. It's the hardware, not the app!This app is great! I love seeing which colors correspond with which music notes, and there are lots of extra features that I wouldn't expect with a free app.

2. Great effort.love it :) I admit the app is not easy for the non intuitive to figure out, but if you *are* a more intuitive type that likes to figure out how something works by dabbling around, this app is great.

3. Can't rate it high enough! Top job!It took some time to learn the icons or functions, as they were not intuitive as apps made in the US, but after watching the instructions video with English subtitles, you will find this app to be very integrative.

4. You can switch to 24khz bandwidth, slide indicator to specific freqs, step history in 0.1sec increments, generate white, pink, gray noise etc., and switch among several views of the graphical output.

5. it has the features most reviewers seem to ask for but can't figure out that's all.Handy little app for audiophiles, sound designers, and audio enthusiast.

6. But it's degree of difficulty to operate and fully understand, makes it un-useable to most individuals that might download it.Wow. Am very impressed with the wide range of features.

7. Thank you for doing such a great job on this cool learning tool! The toggle feature for light and dark modes is nice too.

8. One thing would be a extra switch to change the octaves to there pure form ie 432hz vs 440 hz for the entire scale.

9. It is free, and considering the vast number of features crammed on it, it is well thought out.

10. But, all the features are indexed on a complex busy, and difficult to access key.

11. A great plethora of features, the most for any app.
