Frequency: Sound Generator

Frequency: Sound Generator is a lightweight Chrome extension that lets you generate pure tones in sine, square, sawtooth or triangle waves from 1 Hz up to 22 kHz. It provides an animated waveform to visualize the current tone and easy controls to switch waveforms. Users can drag a yellow dot to adjust frequency, use +/- buttons for fine tuning, and set the volume from 0-100%. This tool is perfect for sound testing, speaker/headphone checks, instrument tuning, tinnitus frequency discovery, or simply exploring audio frequencies on the go.
