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: Explore how your speakers or headphones reproduce selected pitches; playback is not a certified hardware test.
- Binaural Beats: Listen to slightly different frequencies in the left and right channels using stereo headphones; no therapeutic effect is established by this tool.
- 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.
