Comments on Sound Signal Generator for Android

★★★★☆ Alexander Oaks · Aug 23, 2019

It's not bad, I use it for teaching kids about the range of human hearing, however compared to other apps it seems to struggle with low frequencies, with us only starting to hear it around 400hz. Otherwise, it's simple and effective to use.

★★★★★ David Savage · Mar 11, 2020

I have tinnitus and this app is the only one that can: -save settings +multiple tones simultaneously +amplitude per tone +waveform selection

★★★★★ A Google User · Feb 8, 2015

Great! This is the only signal generator that can generate 3 signal at once. I would love to see more option recording and such. Thanks much!

★☆☆☆☆ Robert Struzinski · Aug 22, 2025

I don't see any application that would benefit from this app. It's more like something you'd be seeing in elementary or middle school science class to learn about frequencies relation with sound. Things you should have learned long ago and not be amazed at what this does? It says it's for meditation and relaxation? Who would listen to tones irritating sound to relax. I put up with them for 5 seconds during speaker RTA tests, and it irritates me why would you want to hear it for any other reason?

★☆☆☆☆ Peter Webber · Mar 7, 2017

Would be great but no sound output on my Samsung Note 5 running 6.0.1 with correct settings phone media volume 100%, app volume 0dB, app output ON. Other signal gen apps work for me but not this one, pity coz it seems the best interface.
