## What is Frequency?

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 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. Additionally, pick from a wide variety of notes by taping the notes icon.

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.

EASY CONTROL

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. 

ANIMATED SOUND WAVE

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 FREQUENCY & VOLUME

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%.

NUMEROUS USES:

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.

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.

### 1/5 — ONE STAR

*2026-05-03, version 1.2.0*

This app BLEW OUT 
My speakers on my phone

### 1/5 — Porn Ads

*2026-05-01, version 1.2.0*

Porn advertisements. Another app that has turned the App Store into a trash dump. If you are going to make a free app, make it free, otherwise just charge me a couple bucks. I selected this app because it had a simple feature set and a nice display layout. The Porn advertisements ruined it. Delete!

### 5/5 — I love it !

*2026-03-30, version 1.2.0*

### 1/5 — Not working

*2026-03-29, version 1.2.0*

I don’t think this really works because it is not shutting the upstairs kids up!

Simple and easy to use

### 5/5 — Setting bass gain

*2026-02-27, version 1.2.0*

I used this app to play 40hz sine wave to set the gains on my amplifier for distortion. Not quite using youtube but it worked as youtube wasn’t much help when i got to my crossover calibrations.

### 5/5 — Good

*2026-02-08, version 1.2.0*

It does the exact same thing it’s supposed to do with an extra couple dope suff to

### 1/5 — Terrible ads

*2026-01-10, version 1.2.0*

Would rate no stars if possible. The frequency generator is fine but the ads are killer. Should have an option to purchase ad free. This is not the case with this app. You will end up getting suggestive ads pop up through advertising partners.

### 5/5 — Uses

*2025-11-27, version 1.2.0*

I use this app mainly for meditation. Absolutely love being able to pinpoint a frequency! Great app!!✊🏽🫶

### 1/5 — Has ads

*2025-11-23, version 1.2.0*

This app has ads displayed at the bottom of the screen. Some of them are obscene!  Got to be careful when using this app in public.
