Frequator WApp

I made an tone generator Frequator WApp using the HTML5 Web Audio API. It provides smooth, real-time logarithmic frequency changes.

Features

• Fine-tune frequency in 1 Hz, 0.01 Hz and 0.001 Hz steps
• Choose musical notes (revamped May 2016)
• Shift frequency by a full octave
• Smooth slider movement
• Keyboard shortcuts
• Shareable tone links
• Waveform selection: sine, square, sawtooth, triangle
• Direct numeric frequency input
• Compatible with Chrome, Firefox, Safari, mobile

Other tone generators exist, but many rely on Java or Flash — mine is lightweight, clean, and works directly in the browser.

What can you use a tone generator for?

Experiment with resonance, tune instruments, test audio systems, check hearing limits, or identify your tinnitus frequency for therapy.
