A high volume may also damage your speakers.

How to use the frequency generator

  • Press to play a tone.
  • Press to stop it.
  • Change the frequency one of four ways:
    • Enter the value in the input field
    • Press to decrease by 1 Hz
    • Press to increase by 1 Hz
    • Move the frequency slider
  • Move the volume slider to control the volume.
  • Move the balance slider to control the stereo panning. When balance is set to "100% L R 100%", sound will be equally distributed between the left (L) and right (R) channels.
  • Select from 'Sine', 'Square', 'Triangle', and 'Sawtooth' to change the waveform.
