Propagate gives your games incredibly immersive sound propagation. It works great with or without headphones and is also perfect for taking your virtual reality project to the next level of realism. Propagate simulates three audible cues: 1. Occlusion Control how different objects block sound waves. You can simulate soft objects by having a higher frequency drop-off. 2. Diffraction The diffraction system simulates how sound waves propagate around corners and through complicated geometry. 3. Perception The perception system simulates how sometimes sounds appear to be in different locations due to the geometry of the environment. It is these three cues together that will bring your players inside truly believable sound-scapes. Setting Propagate up is as easy as using light probes. It's also fast and efficient. To hear this for yourself take a look at the demo. Web player demo. Windows standalone demo. Buy Propagate now on the asset store. Roadmap: Improved frequency adjustment (parametric EQ) Improved audio spatialization, simulating audio behind, above, below. (Dependent on Unity 5.2 release). Material presets for occlusion and diffusion (wood, carpet, metal, etc). AudioNode API (support for procedural levels). Research / Experimental: Automatic AudioNode placement. Realtime reverberation calculation. High order sound wave simulation.
