Steam Audio SDK pour Unity.

Bonjour,

Steam/Valve vient de rendre disponible une nouvelle API Audio (C++ et Unity).
Steam Audio a écrit :
What is Steam Audio?
Steam Audio adds physics-based sound propagation on top of HRTF-based binaural audio, for increased immersion. Sounds interact with and bounce off of the actual scene geometry, so they feel like they are actually in the scene, and give players more information about the scene they are in.

What can Steam Audio do?

Binaural Rendering
The simplest thing that any spatial audio technology must do is HRTF-based binaural rendering. This refers to a way of recreating how a sound is affected by a listener's head, ears, and torso, resulting in subtle cues that allow you to pinpoint where a sound is coming from.

Steam Audio's implementation of HRTF-based binaural rendering has a very low CPU overhead; you can handle hundreds, even thousands of sources using a single CPU core. It also minimizes the frequency coloration of audio clips, while maintaining good localization.

Occlusion
Steam Audio simulates how objects occlude sound sources. In addition to the typical raycast occlusion that many game engines already support, Steam Audio supports partial occlusion: if you can see part of a sound source, Steam Audio will only partly occlude the sound. Steam Audio uses your existing scene geometry to occlude sounds, so you don't need to create special occlusion geometry just for sounds.
