About the Online Tone Generator

This browser-based tool generates pure sine waves using the Web Audio API. It is designed for audiophiles, sound engineers, and scientists who need a quick reference signal without installing software.

Features

• Frequency Sweep: Test the range of your speakers or headphones (20Hz - 20kHz).
• Binaural Beats: Create differing frequencies in left/right channels to induce brainwave states.
• Waveforms: Switch between Sine, Square, Sawtooth, and Triangle waves.

How to Use

Simply adjust the slider or type a specific Hz value. For hearing tests, start at a low volume. To use the Binaural Mode, headphones are required as the effect relies on stereo separation.
