Online Tone Generator
What can I use this tone generator for?
Tuning instruments, science experiments (what’s the resonant frequency of this wineglass?), testing audio equipment (how low does my subwoofer go?), testing your hearing (what’s the highest frequency you can hear? are there frequencies you can hear in only one ear?).
Simply enter your desired frequency and press play. You will hear a pure tone sine wave sampled at a rate of 44.1kHz. The tone will continue until the stop button is pushed.
The tone generator can play four different waveforms: Sine, Square, Sawtooth, and Triangle. Click on the buttons to select which waveform you would like to generate.
Please always make sure headphones/speakers are set to a low volume to avoid damage to hearing or equipment.
You can smoothly increment the frequency by clicking in the generator's input box, and pressing and holding the up or down arrow on your keyboard. This will increase/decrease the frequency by 1Hz at a time. If you hold the shift key at the same time, the frequency will change by plus or minus 10Hz at a time instead.
