About this app

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.

Great app, but out of the blue, the sounds from the ads (particularly the temu ad) would just NOT turn off even once I closed the ad. Uninstalled and reinstalled it.. still the same. Gonna have to look for an alternative app now.. might reinstall at some point. Hopefully by then they'll fix the problem, of just remove that buggy temu ad for good(?)

works great on an old lgv20. I purchased the app to support the developer because it works so well for my needs. It has so many controls, and the paid version adds more. I really like the frequency sweep that plays each frequency span youve input in the time you want. Awesome! And having 3 noise choices is perfect. I tried 4 other apps and chose to keep this one.

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 👌
