Exact browser-generated tone
Play or download a precise 528 Hz tone. Generated locally—nothing is uploaded.
Locked frequency
Ready — sound is off.
Sound begins only after this button is pressed.
Start low. Device volume is not the same as sound level at your ear.
Above 60% — lower it if the tone feels sharp, and take breaks.
Local WAV export
Create a mono, 16-bit PCM WAV using the current tone shape and noise settings. Rendering stays in this tab.
The exported file has a controlled signal level; your playback volume slider does not alter the file, and the session timer does not shape it.
Tone is not tuning
The generator above produces one fixed frequency. Retuning an entire piece of music is a different operation.
The sound this page generates
528.000 cycles per secondA single sine or triangle wave fixed at 528 Hz. It is not a song and it does not retune uploaded audio.
People use 528 Hz audio for personal listening and contemplative routines. Small preliminary studies have examined short-term responses, but they do not establish that 528 Hz diagnoses, treats, cures, repairs, or prevents disease.
This page cannot know the sound level reaching your ears. Begin at a low setting, take breaks, and reduce volume if you notice discomfort or ringing.
Straight answers
It is a steady, high-mid pitched tone. Sine is the smoothest option; triangle adds gentle harmonics.
It is about 15.641 cents above C5 in standard A440 equal temperament. It is commonly described as C5 in a system where A4 is approximately 443.993 Hz.
Almost, but not mathematically exact: A4 = 444 Hz places C5 at about 528.008 Hz.
Yes. A whole-second export contains exactly 528 cycles per second at either sample rate, so the loop-safe mode writes no fades and the end meets the start in phase.
The oscillator and the WAV renderer are both fixed at 528.000 Hz, and every whole second of an export contains exactly 528 cycles. Actual acoustic output still depends on your device, audio path, speakers, and headphones.
No established clinical evidence supports medical or "DNA repair" claims. This is an audio utility, not a medical device or treatment.
