Audio-reactive web installation
Atlas Sonor
A sound-art festival wanted the public to “see” the city through sound. I built a page that listens to the microphone (only with explicit consent), analyses the frequencies in the browser and turns them into columns of light on a stylised map.
Nothing leaves the device: the analysis runs locally, and the page also works without a microphone, using archive recordings.
