About Hz Tone Generator

Hz Tone Generator is a small collection of free audio tools that run entirely in your web browser using the Web Audio API: a tone generator for any frequency, dedicated sine, square, sawtooth and triangle wave generators, a noise generator, a binaural beats generator, a frequency sweep, a hearing frequency check and a speaker test.

Nothing is uploaded and no account is needed. We describe each tool honestly: these are tools for testing, tuning and learning about sound, not medical devices, and we do not make health claims about any frequency.
