Generate crystal-clear audio frequencies from 1Hz to 20,000Hz with our advanced Hz generator and frequency generator tool
Perfect for audio professionals, musicians, and sound engineers. Test speakers, calibrate equipment, or create reference tones with precision.
I've tried a bunch of online tone generators over the years, and most of them are either too complicated or sound terrible. This one's different - it covers 1Hz to 20,000Hz with clean audio that doesn't hurt your ears. Perfect for testing speakers, checking headphones, or just messing around with sound.
The best part? It runs at 48kHz sample rate right in your browser - no downloads, no setup hassles. I use it for everything from checking my studio monitors to helping friends figure out their car audio problems. Works on phones too, which is surprisingly handy.
Generate any frequency from 1Hz to 20kHz covering the full spectrum of human hearing
Choose from sine, square, sawtooth, and triangle waves for different applications
48kHz sample rate with smooth transitions and artifact-free generation
Adjust frequency, volume, and stereo balance in real-time with instant response
Yes, our online tone generator is completely free to use. There are no hidden fees, subscriptions, or premium features. You can access all functionality including the full frequency range, all waveform types, and professional-quality audio generation at no cost.
Our tone generator supports frequencies from 1Hz to 20,000Hz (20kHz), covering the full range of human hearing and beyond for professional audio applications.
We offer four standard waveform types: Sine (pure tone), Square (digital/harsh), Sawtooth (bright/buzzy), and Triangle (soft/mellow). Each waveform has different harmonic characteristics suitable for various applications.
Yes, our frequency generator uses high-quality audio processing with 48kHz sample rates, smooth frequency transitions, and artifact-free generation, making it suitable for professional audio testing and calibration.
Yes, our online tone generator is fully responsive and works on smartphones, tablets, and desktop computers. The interface adapts to different screen sizes for optimal usability.
The tone generator works entirely in your browser and doesn't require an internet connection once loaded. However, you'll need to be online to initially access the website.
