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.

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

📲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%.

📑SAVE YOUR OWN PRESETS
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.

🎼PLAY FREQUENCY SOUNDS IN THE BACKGROUND
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.

🔊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.


⚙️ SETTINGS:
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.
Experiment with frequency generator , test speakers, meditate and much more.

vary rarely I leave any feedback but I have tried this app and it works I suppose but I have used it ones and "exited" which is important at this point. exit means app is off but... so I drive a lot and listen to the music, but I couldn't help not notice that some strange sound has appeared in the speakers. it was like this for few days now and today I have noticed that my phone once I have increased volume began to make a noise as well. it was this app despite being off. bypassing.

it's very difficult to accurately slide the frequency selector at the higher ranges. But the worst part is after having had this installed for a while the ads stay up for twice as long as you can use the generator. It just became a pain to try to find the frequency solely only get thrown into an ad and then stuck there for 2/3 of the time you're trying to use the app.

Great app. Does what it says on the tin. You can generate tones from >0 to 22000 of either sine, square, sawtooth or triangle waveform. Also lets you sweep through tones over a specified time period. Useful for musicians, too, as it has every note ready to play in the music section. Additionally, you can make it play a tone for a specified duration, and adjust left/right. Pro version is definitely worth the tiny cost as it lets you export frequencies of specific durations (and gets rid of ads).
