Frequency Generator App DESCRIPTION

Frequency Generator packs ten high-quality and user-friendly signal generation tools:
• Single frequency
• Multi frequencies
• Musical notes
• Binaural beats
• Frequency sweep generator
• Noise generator
• Bass/Subwoofers test
• Speaker cleaner
• DTMF tones
• Sound effects generator

Common use-cases
• Make your own audio experiments.
• Test your hearing: On average, humans hear frequencies between 20 Hz and 20000 Hz, but the hearing can deteriorate with age, especially for frequencies close to ultrasound.
• Find and attempt to mask your tinnitus frequency.
• Tune your musical instruments.
• Relax with binaural beats or white noise.
• Remove water from your phone speaker by generating sound waves in a specific frequency range.
• Play and export randomly generated sound effects. Export requires Android 6.0+.
• Discover how your audio setup handles frequency sweeps ranging from very low frequencies to near ultrasounds.
• …or you can have fun by generating police sirens, cartoonish fall sound effects, etc.

Notes
• This app generates frequencies from 1 Hz (infrasound) to 22000 Hz (ultrasound), and supports decimal values (e.g. 7.83 Hz).
• Available waveforms for the generated signal are: sine, square, triangle and sawtooth.
• Visit the settings to customize the sound generator behaviour: define a timer, enable octave buttons, and more.
• Save your favorite signals as presets via the top-right menu.
• Several studies have found that ultrasounds are not an effective solution to repel mosquitoes. If you still want to use this app as a mosquito repellent, you should know that anti mosquito apps merely generate ultrasounds or near ultraounds (between 15000 Hz and 22000 Hz).
• Keep in mind that the generated tones can be very annoying and irritating for your surroundings. Always use this application responsibly. Also, keep the audio volume reasonably low to avoid damaging your hearing or your audio devices. If you rise the volume to better hear very low frequencies, don’t forget to lower the volume afterwards before playing higher frequencies: the perceived volume of a tone depends on its frequency.
• When generating ultrasonic tones (20000 Hz +) speakers may produce additional parasitic sounds.

App REVIEWS

Kelcy

High frequency range is excellent for creating unpleasant tone (by subject age) to get people out of your office when they've overstayed their welcome. This application coupled with a well placed and clandestine Bluetooth speaker makes getting through the work day much easier with seriously increased productivity. At $3 for the ad free version it's a bargain for the utility, functionality, and ease of use. Many thanks.

Dennystu..

So far, very good ! Easy and straightforward to use, all features and functions work quite well, with NO glitches or hiccups. Bottom line: It does what you need it to do with accuracy and precision, and is extremely comprehensive in it's simplicity and ease of use. I give it a "👍Siskel & Ebert👍" with absolutely no reservations ! ! Good job, I and do highly recommend it 👌

Cecilia

I've been using this way before it had all those other toys, and always liked it's simplicity and design. Now finding all these new options makes me feel obliged to review it after so long! An excellent app, would gladly give it 6 stars if available :) || -- || EDIT: taking away 1 star due to fullscreen ads! I don't mind the permanent one on the bottom, but the big ones are too disruptive, in my opinion.

Scotty

Great functions, but there is something wrong with the app. It constantly crackles no matter what i do to adjust the settings. I've tested this on 3 different stereo's: Car deck, wired studio monitor headphones, and bluetooth ear buds. They ALL produced the same crackling noise. I'd give it 5 stars if this was fixed.

Jonas

This is the one you are looking for. It will play single or multiple frequencies simultaneously. It allows you to program repeating sweeps through frequencies. Awesome for mimicking alarms and sirens. Also a good tool for setting up crossover levels on sound systems and testing frequency response of audio components. I'm sure there are many uses I've overlooked. Incredibly simple to use. Frequencies can be dialed in or entered numerically

pioneers

I love your work, great app but you need to remove the noise from the tones, they will cause tinnitus at even low volume, your signal to noise ratios are all wrong, if you sort this I will pay good money for it as its a great tool...but cannot use it as it is, Please take a look. Also screen colour options would be good along with the ability to run 4 tones would be even better. Cheers

Doug

Initially appearing excellent it's flaws quickly became apparent. Even with the run in background switch on it wouldn't stay on when I used other apps. It even stopped running with simple movements of my phone. When the screen rotated it stopped, which makes no sense. It seems to be very flexible and controllable but the above place it firmly on garbage heap of so many other apps. After years of experience with the Google Play Store I continue to be mystified by the absolute trash they permit.

Matthew

EXACTLY what I've been looking for--purchased! Really a "frequencies" generator because you can play up to three simultaneously. It also has sweeps, different waveforms to choose from, and even white, brown, and pink noise. Selecting frequencies and sweep time is easy because there's a slider, increment buttons, and direct input. The GUI overall is intuitive and smooth. But the best thing for me is the scrolling list of playable musical notes with their frequencies! Thank you!

Joshua

Excellent sound quality and a great selection of functioms that are intuitive and well organized. Ive had no technical issues, everything seems to work fine. Nothing intrusive and the settings menu offers customized color scheme and some other stuff i forgot to write down. Definitely will be installing on three other devices. Big thanX to the developer. I wish all my apps worked as smoothe as this one.

Greg

Got this for messing around; but the fact that it allows you to play notes and also displays the frequency is pretty awesome. I went ahead and bought the app remove ads for 3 bux. The price is totally worth it considering all the audio tools they provide and all of the options you can play around with.

Ryan

I dont have a lot of experience with frequency generators. But i did like this app the best out of the three i tested. It has more options and can have three concurrent oscillators running frequencies. Option to save presets and binaurial + frequency sweep as an added topper. I am pleased. I give it the #1 top spot for frequency generators for free. Now go run and by the actual hardware units that can generate an analog signal while i live in Hoover Town.

Sam

This is not only fun, but a very useful and accessible app. If you like to experiment in scientific ways with electronics and audio, you need a frequency generator and this will give you a very good one at that. A very wide range of frequency is possible, limited only by the audio circuits and speaker in your device. Sine, square, triangle, and sawtooth waveforms are all possible, and can be tuned precisely to any musical note - making this app useful for musique concrete production techniques.

Raymond

Actually, and I know this sounds crazy, but I've been having problems with an old neighbor who uses sound to annoy me. Both infra and ultra. Only way to sleep is to do some myself. This app has lots of options, more than similar and I have a few. Thanks for making such an all around time and sound app.

Jay

Edit. This is a fantastic app for many different reasons... The range of options being the main one.. Also how it can be used in many different ways.. For me it's to ease the pressure of tinnitus which has become more than I can handle alone.. After a bit of research into tinnitus and some of the treatment methods.. I must admit I've found the triple oscillation option to somewhat ease the pressure of which only people who suffer from the problem can understand.. 5 ⭐⭐⭐⭐⭐.

Sayand

I never expected to see so many interesting features in the app! I downloaded it to use only the frequency generation part to mess with my friends. But I recently found out about the other features. A job well done guys. Oh and the music notes features has some bug that causes notes to cease playing if yiu press too many notes in a row

rolls

actually amazing. you have to try it out for yourself. I have no idea where I'd use some(many) of the plentiful features this app has, but I can really appreciate the intuitivity of the UI, the effort that went into this app and the flawless execution I find that the ads aren't annoying at all

Nathan

It has everything I can hear high and low. Only thing I want is the ability to scroll in and more precisely slide the frequency bar. Also as a side thing add dog whistle frequency? Maybe a hearing test mechanic, slow slide up and down use a left or right button to say it it high or low. Found out I have tinnitus at almost exact 11000 hz. Only reason I'm voting 4/5 is there is alot more this app can do, more potential please expand it. Allow saving of favorite frequencies and exporting them.

Travis

Great app! Smooth and accurate tone generation, and more capability in one app than basically every other tone generator. I was looking for a quick way to create tones to help myself focus, I downloaded this one because it had several other tools that are useful to me as a musician and audio engineer. I wasn't disappointed! Even with ads

Sadie

I was so excited to use this app & play around with the different frequencies, and at first it worked great. But when opening it the past couple days, theres something wrong with how ads are set up -- cant seem to get past them no matter how many time i click the "x" and say "No Thanks" to the $3000 solar panel or eyeglass appointments. Maybe its a problem with google admob or whatver is being used for the ads, but i hope it gets fixed soon. For now, the app is not usable.

ccw

This app, as far as frequency and/or tone generators goes, is by far the coolest and most fun to play with compared to others of similar nature. It's fun to play with on your phone or if you have very nice quality stereos and speakers this is really really cool to see what your system can actually do in order to properly tune it to prevent speakers from clipping. Awesome, good work!! Don't stop here you're creative and intelligent i want to see some more cool apps
