## Description

The Multi-Frequency Tone Generator is a versatile and user-friendly Chrome extension designed for audio enthusiasts and professionals. It offers a frequency range from 1 to 20,000 Hz, allowing precise tone generation across all audible frequencies. Users can choose between four wave types — Sine, Triangle, Square, and Sawtooth — for both the main oscillator and the modulator, enabling complex sound effects and signal modulation.

This extension includes features like logarithmic frequency scaling with a fine resolution step of 1 Hz, signal visualization for easy monitoring, and the ability to combine multiple tone signals with individual volume control. It’s ideal for tuning and testing audio equipment, experimenting with unique sound designs, subwoofer testing at low frequencies (20–150 Hz), and evaluating hearing capabilities at high frequencies above 10 kHz. Whether for professional audio tasks or creative sound experimentation, this tool provides precise control and flexibility right on your smartphone.
