Generate tones with multiple waveforms. Adjustable frequency, volume, and multi-tone playback. Pure frontend Web Audio API.
Adjust the frequency slider to select a tone frequency, choose a waveform type, and click "Play" to hear the tone. You can add multiple tones for simultaneous playback.
Four basic waveforms are supported: Sine (smooth and pure), Square (sharp and bright), Triangle (soft and warm), and Sawtooth (rich in harmonics). Different waveforms suit different testing and creative scenarios.
The frequency range is 20Hz to 20,000Hz, covering the full human audible range. Low frequencies (20-250Hz) for bass testing, mid frequencies (250-4000Hz) for speech testing, high frequencies (4000-20000Hz) for treble testing.
Yes. This tool supports multi-tone playback. You can add multiple tones at different frequencies for chord testing, beat frequency demonstration, or hearing tests.
Tone generators have many uses: 1) Test speaker and headphone frequency response; 2) Hearing tests; 3) Audio equipment calibration; 4) Acoustic experiments and teaching; 5) Tuning reference notes.
No. All audio generation happens entirely in your browser using the Web Audio API. No server communication is involved.
