Overview
ECHO 42 is an award-winning artistic experience at the crossroads of immersive theatre, podcast, and escape game. Born from an idea conceived over 10 years ago, the concept is an immersive sound theatre where you hear the actors without seeing them, letting the listener's imagination build the entire world. Technology becomes invisible to let the narrative pulse: a breath, a footstep, a tense silence… the listener takes control, and the space responds. Entirely self-produced, this debut was an unexpected success, running for six months in Paris in the historic former Museum of the Resistance.
Technical details
The main technical challenge was to make complex technology feel simple, fluid, and magical. This required true feats of engineering and creative technology to orchestrate and automate the experience from end to end. Leveraging advances in spatialized audio, micro-electronics, and AI, the team had to tame latencies, ensure millimeter-perfect synchronization, and implement contextual triggers based on participants' movements. This was achieved in just two months of intensive, self-produced creation by a dream-team of co-creators (io-stud.io, Sculpteurs de Rêves, Start-Rec).
