About This Tool

This tone generator produces precise audio tones using the Web Audio API with adjustable frequency, waveform type selection (sine, square, sawtooth, triangle), volume control, and frequency sweep modes. It is useful for audio engineers testing speakers, musicians tuning instruments, educators demonstrating sound wave properties, and anyone who needs to generate specific audio frequencies. All tone generation happens directly in the browser with no downloads required.

How to Use

  1. Set the desired frequency using the slider or enter an exact value in Hertz
  2. Select a waveform type: sine, square, sawtooth, or triangle
  3. Adjust volume and optionally enable frequency sweep mode for range testing
  4. Click play to generate the tone and stop when finished
