AURA by Pablo Valbuena

Aura - Pablo Valbuena

Audiovisual installation, St Paul's Cathedral, London 2023

Aura is a live installation that translates the sounds of the cathedral’s rituals into pulsating light. It listens to the sounds, voices and music generated in each ritual and transforms their frequency spectrum into a spectral aura of light projected at an architectural scale.

- Pablo Valbuena

A realtime tool built with TouchDesigner processes the live audio from various sources in the Cathedral (choir, organ, altar) and represents its frequencies on a 20-meter column of light.
