About Tone Generator

The Tone Generator produces precise audio tones using the Web Audio API. Adjust frequency from 20 Hz to 20,000 Hz (the full range of human hearing), choose from 4 waveform types (Sine, Square, Sawtooth, Triangle), and control volume. Changes apply in real-time while playing. Perfect for audio testing, hearing range checks, music tuning, sound design, or educational demonstrations of waveform types and frequencies.
