Frequency Generator - Audio Tools & Ultrasound

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 👌

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.

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

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

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 ⭐⭐⭐⭐⭐.

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

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

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.

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.

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

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.

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.

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

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!

Very useful diagnostic tool. Easy intuitive interface and no unexpected issues arising. Ads are there, of course, but are not excessive. I needed a two tone source for peak envelope power measurement and this was the simplest way to do it.

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.

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.

It's cool, I downloaded it as a bug deterrent, but the science on that is sketchy, but it's a really cool tool, binaurals, game sound effects and the phone generation and note tool I've used for choirs and tuning instruments, and testing headphones and speakers is brilliant fun. It's generally just great fun to mess about with and nice robust reliable buttons sliders and menus, makes me feel super sciency!

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.

The output is smooth and soft, unlike most others that are very harsh. Great volume. I like binaural beats. It would be nice if you could sweep the beats. All sweep methods: bounce, hold, hold at intervals, stop, etc. Solfeggio and monaural beats in multi oscillator. Excellent app. Simple to use and good decimal value.

Very professional, user friendly app. Some 'crackling' observed while using the sweep function. It would be great if that could be fixed.

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.

I just opened up this app for the first time in a while, it has SO MANY NEW FEATURES. I used to use this to find the cutoff/crossover frequencies for my speakers, but I will now also be using this to help me with my music production. the ads can be intrusive but there is an option to remove ads for $3, which I will most likely do.

Ive been looking for a thing like this to apply to my tuning and tweaking on my guitar. Trying to get equal temperament to work for me. I also like this app because It allows me to test my aural scope in frequecies above and below the average. Such a small app, and yet a lot of potential to explore the musical sound realm. I think Ill have a ton of fun. Thanks.

Works great and love the features. However I do not seem to have volume and balance control on my tablet in multioscillator mode, but I do have these on my phone. My tablet is 10 years old though. Curious as to what the problem/difference might be.

The brown noise actually makes you lose your bowels, totally cool. You'll get five stars once my diapers arrive and don't send the reusable or recycled ones. No really a great app. I actually was sble to create a frequency that turned non-shielded motors off, super cool. This is a real frequency generator.

I think your app is pretty cool it's not like the rest that are out there I like the fact that there's so many options and cool buttons! Now if you would just put a recorder built into it so we could save the files as mp3 Mp4 wave that would totally rock!! Keep up the good work!!
