Are you familiar with the situation when you need to test speakers, tune a musical instrument or test your hearing for high and low frequency perception, but there is no professional equipment at hand?

Our tone generator will instantly create a pure sound wave of the desired frequency right in your browser. Calculations are performed locally using the Web Audio API, ensuring high audio fidelity.

You can smoothly change the frequency in Hertz, adjust the volume and choose the waveform (sine, sawtooth, square, triangle). A sweep mode (smooth frequency change over time) is also available.
