Please listen with headphones. Click any scene to make it live, then look around with W A S D — the soundfield rotates with your view, so each sound stays fixed to its source in the world rather than to your head. Every scene is worth turning through a full circle: several sources sit behind you.
This demo is spatial audio. On laptop or phone speakers the left and right channels bleed into each other and the effect disappears entirely — you will hear the sound, but not where it is.
