Online Tone Generator
Whether you're tuning instruments, testing audio equipment, or exploring sound frequencies, our sound frequency generator provides precise tone generation from 1 Hz to 20 kHz. This advanced frequency tone generator is perfect for musicians, audio engineers, and anyone curious about the world of sound frequencies.
Features of Hertz Generator
- •1 Hz – 20,000 Hz Range — Cover the entire human hearing spectrum from the deepest sub-bass to the highest treble, all from one tool.
- •Stereo Balance Control — Pan audio left or right independently for binaural and spatial hearing experiments.
- •No Installation Required — Runs entirely in your browser using the Web Audio API — nothing to download or install.
- •Shareable Settings — Copy a link that encodes your exact frequency, waveform, and volume so others can open the same tone instantly.
- •Real-Time Waveform — Watch a live oscilloscope render as you adjust settings, giving instant visual feedback on your tone.
- •Works on All Devices — Fully responsive and touch-friendly — use it on desktop, tablet, or mobile without any compromise.
Use of Tone Generator
- •Hearing tests — play specific frequencies to check your hearing range or identify tones your ears struggle with.
- •Speaker and headphone testing — sweep through frequencies to find weak spots, rattles, or resonance issues in your audio equipment.
- •Tinnitus masking — use a matching frequency to temporarily reduce the perception of ringing in the ears.
- •Music tuning and ear training — generate reference tones to tune instruments or train your ear to recognise intervals.
- •Sound therapy and meditation — work with Solfeggio and other healing frequencies for relaxation, focus, or deep sleep.
- •Scientific and educational use — demonstrate wave properties, resonance, and acoustics in classrooms or research.
- •Audio equipment calibration — produce precise tones for calibrating mixers, amplifiers, and recording gear.

Safety Warning
Extremely low or high frequencies can potentially damage audio equipment and hearing. Always start with low volume and gradually increase. Do not use at maximum volume for extended periods. If you experience discomfort, stop immediately.
