π FAQ
What waveforms are supported?
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.
What is the frequency range?
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.
Can I play multiple tones simultaneously?
Yes. This tool supports multi-tone playback. You can add multiple tones at different frequencies for chord testing, beat frequency demonstration, or hearing tests.
What are the practical uses?
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.
Is my data uploaded to a server?
No. All audio generation happens entirely in your browser using the Web Audio API. No server communication is involved.
