What is this?

Just a very simple tone generator, thanks to Tone.js

  • Click "Start" to start the tone, and "Stop" to stop it. Click "Reset" to reset the frequency to 440 Hz and stop the audio.
  • Adjust the frequency by clicking the buttons or dragging the slider.
  • While using buttons, long press (doesn't work on mobilešŸ¤”) can increase the frequency faster, hold down the Shift key to adjust the frequency by 1 Hz.
  • You can also type in the frequency directly by clicking the number.
