How to use the Solfeggio Frequencies Player

  3. Adjust the volume slider to a comfortable level.

Why use ZillaKit's Solfeggio Frequencies Player?

The solfeggio scale is a set of nine tones — 174, 285, 396, 417, 528, 639, 741, 852 and 963 Hz — that have circulated in sound and wellness folklore for decades, each traditionally associated with a particular mood or theme. This player generates every tone live using the Web Audio API as a pure sine wave with a smooth attack and release envelope, avoiding the harsh clicks you'd get from an abrupt on/off. The 528 Hz tone, often nicknamed the "love frequency" and one of the most searched solfeggio tones, sits alongside the other eight so you can compare them side by side. A volume slider and an optional session timer (15, 30 or 60 minutes) make it easy to settle in for a longer relaxation or focus session without needing to watch the clock. Everything is generated on the fly in your browser — there is no audio file to upload or download, no signup, and no limit on how many times you listen.
