Frequency Sound Generator

I gave you 5 stars because your app is simple clear and intuitive. But one big drawback is it does not play in the background. It sucks to keep the phone screen on and also not being able to switch to other apps while playing. Cause if I do it shuts off the sound. Please make this little change and I will stick to your app forever. Good luck.

When i downloaded it, all was fine; now there is no sound. I like my frequencies but am finding that reloading becomes a labor. It is best to have a digital load, and log of signal successes. I asked for help but have not heard from the company. The root problem in Moto G 3 may be the answer and the challenge? Snoops like to wire mics as they need an entry point this App maay have posed vulnerable?

Awesome app!! I would recommend to any dog trainer, musician, or even someone just trying to get rid off mosquitoes in their home.

Great app, but unfortunately I can't get it to send sound over Bluetooth on my Nexus 6p. I've checked my volume settings and I'm running the latest version of Android so I'm not sure what the problem might be. I'll add that last star if you could help me out!

This app is awesome! I can prank anyone I want,and they'll think it's in their head(and...errr...confidentially,soon it will be????????). But,errr,I would apreciate if you could tipe in the frequency that you want instead of having to sit and turn the toggle,it's extremely tiring if you want to get to high frequencies,but atleast you can save it so you don't have to toggle all the way up every time.

It functions almost flawlessly everytime, don't expect to hear beyond your normal hearing range and don't expect your phones speakers to be able to reproduce the highest frequencies as it's beyond there capabilities, specific laboratory equipment is required for this, on the whole a well made and perfectly usable application

Amazing! I use this a lot to test the bass on speakers and headphones or to annoy my friends. Ads are pretty invisible, I would and have recommended this app.

Highly customizable, 3-way frequency generators make it possible to create some amazing sound combinations. With a life-long interest in sound/noise (versus just musical melodies), this app really delivers the goods. AND it's light on permissions too! Excellent. Thank you.

Please add switch off display So your apps can save battery more longer Now your apps must at on display. When I turn off display sound off too Other app can do turn off display , sound on

I really like the simple and easy to use layout. Although one time, I wanted to listen to the sounds of the frequencies I made while using other apps, but realised this is not possbile. Something like background play would be really useful.

Its nice but want more advanced options with amplitude, range and more option to save. But I ???? love this app. Worth 5 ???? star

I've found a harmful frequency....IT HERTZ! XD seriously it did hurt though and now I'll be doing tests with a frequency from the earth 7.83 Hz

Do add a feature to save a loop with desirable length in mp3 or some format; want to turn of my screen and hear my jam on a loop

It may be a big with just my phone, but it didn't work for me at all. Double checked my settings. No audio.

Love the app! Used it to get rid of pesky rats, definitely worth the five stars and download for anyone with a rodent problem! :D

But it's a great app as I used it in my other phn!????

It plays a frequency the first time one of the oscillators is played. But stopping it and restarting it or starting a different oscillator just gives me a 'bip' and then nothing, silence. To get it to work again, I have to quit the app and then restart it. When I do, I get the same results: works as long as I don't stop it. :(

Nice app, i want to turn up all the way to repel stray cats but when i do that, my wife keep walking away, weird

IT NEED'S 2 PLAY IN BACKGROUND & BE ABLE 2 PLAY MUSIC IN THE PHONE AT THE SAME TIME I'M TRYING 2 RECORD WITH THIS APP

Cool app. Wish it had decimals for hz though. I cant use it cause I need more accuracy.

This app makes it easy to set up 3 layered sounds in many variations and save the settings for later use. Excellent design and execution. Bravo.

It's okay, but it really should go upto at least 53 khz on the high end. I am looking for something that does this and can be used for school labs too.

Love this app. Wish it had a switch to [run in background]so screen would not stay on and wear battery down.

It's great HTC is all about the sound I have 2 spaekers and when I'm at school lots of my teachers are old and I annoy everyone in the class but the teachers are like what??

Had sound generator for a long time now all the sudden all does it stop

I get to annoy all my friends and its funny to mess around with my friends

Useful audio tool. Nice functions too

But will the high frequency do any damages to my speakers?

Nice, but it could do with a few features (left right balance, presets for DTMF tones...)

omg thats what i was looking for a long time but finally found it thanks a lot to the makers

Yes i kill poeples ears thank you gods

Well designed app. I used it for finding the phase of speakers of my 5.1 home theatre syster, by listening to the generated tone 2 speakers at a time.

Popping when starting tones. Cannot use this for that reason.

The best thing to play out loud in class and is really easy to use!

Older people cannot hear above 16,000 ... but I would like to make a ringtune option, if there was an option to save a specific frequency and make it a ringtone this would be the best.... also 6,350 kills human ears the most if you want to annoy someone.

Exactly what I was looking for, easy to use, and extremely effective at ruining subwoofers and my friends eardrums.

It's the best I get to mess with peoples ears but besides that I love this app

App helps me in disturbing my neighbors but well done bros...

Yes i kill poeples ears thank you gods

Useful audio tool. Nice functions too
