What is Tone/Frequency Generator?

Tone/Frequency Generator creates precise audio tones with the Web Audio API. Generate sine, square, sawtooth, and triangle waves at any frequency from 20Hz to 20kHz. Great for audio testing, tuning instruments, or sound experiments.

How to use

  1. Set the desired frequency using the slider or by typing a specific value in Hz.
  2. Select a waveform type: sine (pure tone), square, sawtooth, or triangle.
  3. Click Play to hear the tone. Adjust volume and download the generated audio as a WAV file.
