Generate pure tones from 1 Hz to 22 kHz with sine, square, triangle or sawtooth waves. Play several tones at once, send each to the left or right channel, run sweeps and download a WAV.
This generator builds tones in your browser with the Web Audio API, from 1 Hz up to 22 kHz (capped at half the sample rate of your audio, usually 22.05 or 24 kHz). You type the frequency to the thousandth of a hertz or drag a log-scale control, pick the waveform (sine, square, triangle or sawtooth), play up to six tones at once, send each one to the left side, the right side or both, and run logarithmic or linear sweeps between two frequencies. You can pick musical notes with A4 at 440 Hz (the ISO 16 standard) or another tuning, and download the result as a WAV of any length you choose. Every change uses a few-millisecond ramp so it does not click, and the whole state goes in the link so you can share it.
Paste the code into your HTML and the tool shows up on your page, without J-Kit's navigation and ads. It still runs in the browser of whoever visits your site.

From 1 Hz to 22 kHz, limited by the Nyquist limit of your audio: half the sample rate. On a 44.1 kHz device the technical ceiling is 22.05 kHz and the tool uses 22 kHz. If your audio runs at a lower rate the frequency is reduced and a notice appears. Human hearing spans roughly 20 Hz to 20 kHz in young people, so below 20 Hz you feel vibration instead of hearing it, and above 18 to 20 kHz many people hear nothing at all.
