What is Tone/Frequency Generator?
Tone/Frequency Generator creates precise audio tones using your browser's Web Audio API. Generate sine, square, sawtooth, and triangle waves at any frequency from 20Hz to 20kHz — perfect for audio testing, tuning instruments, or sound experiments.
How to use
- Set the desired frequency using the slider or by typing a specific value in Hz.
- Select a waveform type: sine (pure tone), square, sawtooth, or triangle.
- Click Play to hear the tone. Adjust volume and download the generated audio as a WAV file.
