⚙ Under the hood

Interactive 2D concert-hall cross-section for computing reverberation time with Sabine's formula. Adjust room dimensions and per-surface absorption coefficients for floor, walls, ceiling and audience seating, then trigger a clap impulse to watch the live RT60, room volume and total absorption update alongside a Schroeder-style decay curve.
