About Frequency Generator

Welcome to the Online Frequency Generator, a professional-grade web application designed to generate precise audio tones and waveforms directly in your browser.

Our Mission

To provide a free, accessible, and accurate tool for audio testing, equipment calibration, and hearing health awareness. We believe that professional audio tools should be available to everyone, from sound engineers testing expensive equipment to students learning about wave physics.

Core Features

• Precise Tone Generation: Generate frequencies from 1 Hz to 20,000 Hz with high accuracy.
• Stereo Heading Test: Advanced bilateral hearing screening to check Left and Right ears individually.
• Multiple Waveforms: Switch between Sine, Square, Triangle, and Sawtooth waves for various testing needs.
• Real-time Visualization: See the sound you hear with our responsive oscilloscope.

Technology

This tool is built using the emerging Web Audio API standard, allowing for synthesis-level audio generation directly within Google Chrome, Firefox, and Edge. Unlike play-back based tools, our audio is generated mathematically in real-time, ensuring zero compression artifacts.
