Systems that translate
nature into sound

Each product uses computer vision to analyse a different aspect of the natural world and convert it into MIDI — ready for your DAW, modular synth, or live performance setup.

Other Sonification Projects

01

Pulsar Sonification

Pulsar timing data, turned into sound

Pulsars are rotating neutron stars that sweep a beam past Earth with extraordinary regularity. This project sonifies their real timing data — the arrival times of those pulses and the dispersion measures that describe how far the signal has travelled — so you can hear the structure in a dataset that is usually only ever plotted.

Key capabilities

  • Built on real pulsar timing data, not synthesised stand-ins
  • Pulse arrival times drive rhythm; dispersion measure shapes pitch
  • Runs in the browser — no MIDI hardware required
  • Try it out here: pulsar-sonification.netlify.app
02

Scanline

Hear the outlines in any image

Scanline translates the contours of an image, video, or webcam feed into a musical scale. Where the other tools read colour and movement, this one reads shape — the edges it traces become the notes you hear.

Key capabilities

  • Multi-scale contour tracing
  • Works with a still image, a video file, or a live webcam feed
  • Traced outlines are mapped onto a musical scale
03

DESIsonica

A sky survey you can listen to

DESIsonica translates astronomical survey data into structured sound with synchronized visualizations. It draws on data from the Dark Energy Spectroscopic Instrument (DESI) Data Release 1 — a survey that has measured redshifts for millions of galaxies, quasars, and stars — and converts that data into bin-triggered spectral wavetable sonification you can listen to and explore in a browser.

Key capabilities

  • Multiple views of the same data including 3D skymap, histogram bins, and spectral wavetable
  • All sound-generation contained within the browser; no need for MIDI instruments or external audio interfaces
  • A truly science-aligned approach to sonification
