About
Heliosinger turns live NOAA solar-wind data into sound.
DSCOVR sits about a million miles upstream of Earth. The app maps that plasma and magnetic field, plus GOES X-ray measurements and the Boulder magnetometer, into a small choir of vowel-formant voices. There is no demo track. When the sun is quiet, the sound is quiet.
How the mapping works
• Solar-wind speed → pitch
• Particle density → vowel and harmonic richness
• Bz, the north–south magnetic component → chord quality
• Planetary Kp → beat
What's included
• Live sonification on the Listen tab
• A live Sun visual with current telemetry and a short explanation of why it sounds the way it does
• 15- and 30-minute timers that keep playing with the screen off
• Storm and flare push alerts
• A Home Screen widget, Lock Screen Now Playing controls, and a Live Activity while a timer is running
• A six-second capture of the current sound and picture
Heliosinger+ is $4.99 once. Not a subscription. It adds:
• Background audio with no 30-minute cap
• Session timers up to 8 hours
• Spatial audio on supported AirPods
• Aurora alerts filtered by a rounded latitude or a chosen region
iPhone only. Headphones recommended.
For awareness and ambient listening — not a safety, forecasting, navigation, or emergency tool. Use NOAA SWPC for operational space weather.
