What is Online Tone?
Online Tone Generator lets you play steady tones right in your browser, from 20 Hz to 20 kHz. It’s built for quick speaker checks, audio calibration, music practice, and hearing awareness. You can pick common reference tones like 440 Hz or 1 kHz, switch between sine, square, sawtooth, and triangle waves, and control the volume carefully for safe testing. The tool runs locally, so there’s no account or install needed.
