About this app

Are you producing? Want to sound test your speakers or tune your instruments? Or simply, do you want to generate sounds and listen to the generated sounds in different frequencies? Well, then you need a frequency sound generator and sound analyzer to produce sound waves in different frequencies. Introducing Frequency Sound Generator!
Frequency Generator Sound player lets you generate a sine, square, sawtooth or triangle sound wave with a frequency between 1Hz and 22000Hz (hertz). It produces accurate tone & soundwaves while being simple and easy to use.
No matter if you need to sound test and generate high frequency sounds or low frequency sounds, our frequency tone generator is your #1 best solution.

Frequency Sound Generator allows you to easily change the soundwaves from the main menu. Simply tap on the sound wave icon and pick between sine, square, sawtooth or triangle. Additionally, pick from a wide variety of notes by taping the notes 🎵 icon.

You’ll love the animated sound wave function which visually represents the sound for a given frequency. You can change waveform by clicking on a round button at the left side and get a different sound and animated wave.

Adjust the sound generating frequency easily by dragging the yellow dot. Make use of the - & + buttons for added adjusting precision. Additionally, control the volume of the generated sounds from 0-100%.

By clicking on the three dots in the top right corner you can create and load your own favorite frequency sound presets so you do not have to dial it every time again.

In the frequency generator app settings, you can choose if you want the frequency sound to continue playing in the background when you minimize the frequency sound playing app.

This sound generating app can be used in multiple use cases:
Test your hearing. A human being is capable of hearing frequencies in the average range of 20Hz-20000Hz. This range is getting smaller by age, so it’s interesting to sound test your hearing capabilities.
Test speakers and headphones for the high end (treble) and low end (bass) tones.
● Use this app as an instrument tuner when playing or producing.
Cleaning water from the speaker. Since sound is making small vibrations it can help to shake off unwanted water from your speakers.
● Find your tinnitus frequency.

There are few settings you can adjust to customize Frequency Generator app behavior.
● Change frequency slider range to allow you more precision while selecting frequencies.
● Choose between two slider scales: linear or logarithmic.
● Low latency setting enables high-performance low latency audio which makes slider more responsive and eliminates lag. (NOTE: Low latency setting may result in high frequencies on some devices sound inaccurate, especially on higher volume.)
● Enable or disable decimal precision up two decimals in case of need for more precise sound generation.
● Change +/- button step for even easier adjustments.

NOTE: Since mobile phones are not high-quality audio sources and in-built speakers may vary in quality, sometimes users can hear sounds at very low or high frequencies even beyond the scope of human hearing. That noise is not sound of a given frequency but static or “parasite” noise generated by your mobile device. For the best experience use a pair of good quality headphones.

One of the best audio generators on the playstore. The timer function (ability to play a tone for a set number of sec/min) is really handy for confusing your enemies into thinking you are somewhere when you are not, and the sweeper function is able to counter any possible sound frequency your opponent is hitting you with long enough to escape. All in all, a wonderful app for counter-intelligence. I would like customizable home screen widgets for faster access, but can't have it all I guess lol!

App is nothing spectacular due to improper display when in landscape mode, volume control does not work. Random volume fluctuations is extremely annoying. Why would volume suddenly & increase a lot just by normal use of my phone? Such as when I open another app the volume shoots way up. Makes no sense. Also, volume randomly changes when nothing else is happening. C'mon guys - please pay attention and get it fixed and you'll be on top of the heap.

So far from what I've seen, it's very useful for what I'm looking to do. If I could suggest an addition, I'd say to add the ability to set the frequency to different ears. For example, set the left ear to 144HZ and the right ear to 186HZ to get an interpreted frequency of 42HZ. All in all well made and I love the fact I can have it playing when I'm watching other things with audio.
