## Description

**Frequency Generator (Sound)** is a versatile Chrome extension designed to generate various sound waves including sine, square, sawtooth, and triangle across a frequency range of 1Hz to 22000Hz. Perfect for testing audio equipment like speakers or tuning musical instruments with precision.

Advanced settings include changing frequency slider scales (linear or logarithmic), decimal precision, volume boosting, low latency for responsive audio, and octave controls. For optimal sound quality, using good headphones is recommended.
