Sound doesn't travel in straight lines. The space between a source and a listener defines how it's heard. SweejTech Propagation takes a physically grounded approach, not a simulation, but an experiential system that gives sound designers full control over how obstruction is perceived and applied.

Harnessing the GPU, the system evaluates obstruction dynamically at runtime. That means it responds to anything: destructible environments, player-generated content, worlds that change as you play. No baking, no preprocessing, no compromises. The system is designed to scale, laying the foundation for a comprehensive acoustics solution as the technology evolves.
