About Sound Cycle

Sound Cycle generates real-time ambient music composed entirely by nature. Wave height shapes synth filters, sun position controls brightness, and moon phase drives atmospheric depth.

Every station is a real ocean sensor — surface buoys measuring waves and weather, or deep-ocean DART tsunami sensors on the seafloor. Data updates every 30 minutes, and the music continuously evolves as conditions change across the world's oceans.

How it works

Ocean data (wave height, period, wind, temperature, seafloor pressure) is fetched from 27 NOAA stations worldwide and normalized to musical parameters. Celestial data (sun altitude, moon phase) is computed in real time. These parameters drive five generative voices: a deep drone, ocean pad, shimmer layer, melodic fragments, and wind texture.

No two moments sound the same. The music is literally composed by the world's oceans.
