Schumann Sferics Generator

The Earth has a sound. Between the ground and the ionosphere a vast cavity resonates, driven by around 50 lightning strikes per second worldwide: the Schumann resonances at 7.83 Hz and their overtones. Add the distant crackle of sferics, the ping of tweeks and, at night, the falling whistle of whistlers.

Schumann Sferics generates this sound live – in the rhythm of your location. The sun's position, day and night and the season shape how often events occur and how they sound. Livelier by day, calmer and wider at night.

A SKY THAT LISTENS Every event becomes visible the moment you hear it: • whistlers streak across the sky as shooting stars • tweeks make stars glint • distant lightning glows softly behind the horizon • sun and moon stand where they really are – with the real moon phase

FOR FALLING ASLEEP • sleep timer with a gentle fade-out • night mode that softens the higher frequencies • keeps playing with the screen locked • a dark, calm screen without distractions

PRO • Live space weather: Kp index from NOAA, aurora above your horizon during geomagnetic storms, a restless sun • Living Schumann drift: the modes wander with the day, the year and the sun • all night in the background • mix with other apps

Pro is available as a monthly or yearly subscription (7-day free trial) or as a one-time purchase.

HONEST Sound and sky are generated, not measured. What is real is the rhythm of your location, the moon phase, the space weather and the physics of the events. Your location never leaves your device.
