What is the Tone Generator?
The Online Tone Generator plays a clean sound at the exact frequency you choose. Musicians use it to tune instruments (A = 440 Hz), engineers to test speakers and subwoofers, and teachers to show how pitch works.
Pick a frequency with the slider, type it, or use the fine-tune buttons. Choose sine, square, triangle or sawtooth waves and download the tone as a WAV file.
How to use the Tone Generator
- Press Play (start with a low volume).
- Move the slider or type a frequency in Hz.
- Use ± buttons for fine steps, change the wave shape, or download a WAV.
Useful frequencies
- 440 Hz – musical note A4, the tuning standard.
- 50 / 60 Hz – mains hum.
- 1000 Hz – standard audio test tone.
- 20–60 Hz – test your subwoofer bass.
Safety
Start at a low volume. Very high or loud tones can be unpleasant and may harm hearing with long exposure.
This Tone Generator is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
