## How it works

The signal generator allows you to create precise acoustic signals and noise directly in your browser.

Select a waveform (e.g., sine for pure tones or noise for testing purposes) and set the desired frequency in Hertz and the volume. Press start to play the tone immediately, visualized live in an oscilloscope. Ideal for testing audio equipment or sound design.

Synthesizes waveforms and noise using the Web Audio API. Controls frequency and gain dynamically, routing audio output to an oscilloscope for real-time visualization.
