About Us

Who We Are

Online Tone Generator has been a trusted resource for musicians, audio engineers, and sound enthusiasts since 2011. What began as a simple tone generator has grown into a comprehensive suite of professional-grade audio tools, all completely free to use in your web browser.

Cutting-Edge Web Audio Technology

We leverage the power of the HTML5 Web Audio API to deliver studio-quality audio tools directly in your browser. This modern web standard allows us to provide:

  • Precision tone generation with sample-accurate timing
  • Low-latency audio processing for real-time effects
  • Cross-platform compatibility without plugins
  • Advanced audio routing and mixing capabilities

Our tools are compatible with Chrome, Firefox, Safari, Edge, and other modern browsers supporting the Web Audio API specification.

Musical Precision

All frequencies on our platform are calculated using equal temperament tuning with A4 = 440Hz as the reference pitch. This industry-standard approach ensures:

  • Consistent musical intervals across all keys
  • Accurate semitone ratios (12th root of 2)
  • Compatibility with modern instruments and tuning systems
