Tone Generator

Generate tones and frequencies online, from 1 to 20000 Hz, generate sinusoidal, square, triangular and sawtooth waves online. 🎵


Move the slider to set the frequency or write it in the text field, choose the oscillator type in the selector and click the start button. In the computer version, on the bottom left there are three buttons: the first one is used to graph the wave that is selected (at the moment it only draws sine waves); the second is to change notes and the third is to download the sound in a .wav audio file online (it only downloads sine waves).

What can I use it for?

You can use it for scientific experiments, scare away animals, tune instruments, test up to what frequency your ear can hear,... 😯

Experiments: Observe sound frequencies visually with experiments: control fire, create spirals of water, make sand drawings,...

Tinnitus: If you have tinnitus, this frequency generator can help you better select the sounds to carry out a TRT (Tinnitus Retraining Therapy) masking therapy. More information about TRT.

Alzheimer's: There are studies that suggest that subjecting Alzheimer's patients to a frequency of 40Hz can improve their cognitive state. More information about Alzheimer and 40Hz vibrations. (Please note that this tone generator is not a medical device. We do not guarantee anything!)
