Topic: Audio, Programming

Format: Session

Vault Recording: Video

Audience Level: All

The developers behind the VR stealth game 'Budget Cuts' discuss how they used Steam Audio to implement advanced spatial audio features for their title. The talk provides specific examples of spatial audio technology and how it enhances gameplay and immersion, including: HRTF-based binaural rendering for locating enemies; occlusion and transmission for modeling how sound is affected by vents or other openings; and real-time physics-based reverb for modeling smooth variations and subtle details in environmental reverb. The talk also discusses how the needs of the game informed improvements in how Steam Audio integrates with Budget Cuts' game engine, Unity. Finally, the talk discusses some of the limitations in audio engine architecture when it comes to advanced spatial audio technology, and offers some suggestions for addressing them.


Attendees will learn some of the technical details behind the spatial audio technology used in 'Budget Cuts', and how technical choices were driven by artistic goals. Technical audience members will gain a deeper insight into how advanced spatial audio needs can drive requirements in game engine and audio middleware layers.

Intended Audience

This talk is intended for sound designers, game developers, VR developers, audio programmers, engine/middleware developers, and spatial audio researchers. Familiarity with VR and high-level spatial audio concepts (binaural rendering, occlusion) will be helpful.
