Sound propagation middleware
Advanced sound propagation for video games. Bring spaces to life with convincing acoustics, creative control, and a system that works with your audio engine.
01 / Overview
BvSound offers a comprehensive, high-fidelity solution for sound propagation in video games, alongside a suite of game audio features. It supports all major game platforms and is designed to integrate with any game engine or audio middleware, with out-of-the-box support for Wwise, FMOD, and Unreal Engine.
Simulate transmission loss through materials, diffraction around portal edges, and sound repositioning. Obstruction accounts for sound passing through and around smaller obstacles along each propagation path.
Model indirect sound with early and late reflections that work together as a complete reverb solution. Connect each sound to the acoustic character of the space around it.
Respond to real-time changes in sound geometry and build environmental ambiences with volumetric emitters and flexible emitter shapes. Preserve sound quality with smooth transitions and minimal artifacts.
01.1 / Overview — For sound designers
Convincing propagation is the starting point. BvSound gives sound designers control over each feature, so the acoustics serve the creative direction of the game, with an emphasis on sound quality, smooth transitions, and minimal artifacts.
Tune and customize propagation features to match your project. Shape how sounds travel through materials, around obstacles, and into the surrounding space, without giving up control of the final experience.
Bring direct sound, reflections, reverb, and environmental ambience together in one system. Use volumetric emitters and configurable emitter shapes to create sounds that occupy spaces, while geometry changes are handled in real time.
01.2 / Overview — For programmers
BvSound is a high-performance runtime library that sits between your game and its audio playback solution. Add a comprehensive propagation feature set without investing years of development or maintaining all of the specialist expertise in-house.
Integrate with your chosen game engine and audio middleware while keeping playback in your existing audio solution. Customize memory management, sound geometry handling, raycasts, and serialization to match your architecture.
User-defined sound geometry drives transmission loss, diffraction, repositioning, and late reflections. Raycasts in the game world handle obstruction and early reflections.
The raycast-based obstruction system scales with configurable raycasts-per-frame budgets and supports hardware raycasts on platforms where they are available.
02 / Integrations & platforms
Ready-to-use integrations. Flexibility for custom integrations. Support for all major game platforms.
BvSound is designed to integrate with any game engine or audio middleware. Our customers have successfully integrated it into proprietary game engines, audio engines, and editors.
Discuss your integration requirements ↗BvSound’s customizable API lets you connect its core systems, including memory management, logging, physics, and serialization, to the corresponding systems in your engine.
BvSound’s custom mixing provides a consistent audio experience across engines and platforms.

03 / Licensing
Choose the license components your project needs and pay only for those.
For example, you may want to license only automated geometry generation, or runtime features without full source code access or support.
Get all BvSound license components at a lower total cost than purchasing them individually.
| License component | Custom | Full |
|---|---|---|
| Commercial use | Included | Included |
| Continuous updates | Included | Included |
| Runtime features | Optional | Included |
| Integrations | Optional | Included |
| Automated geometry generation | Optional | Included (closed beta) |

06 / News
BvSound's automated geometry generation feature is now available in closed beta. We’re inviting teams to try it out in their projects.
Contact us to participate ↗007 First Light becomes the latest game title to use BvSound middleware for high-performance real-time simulation of sound propagation.
Released to critical acclaim by IO Interactive, the creators of the HITMAN series, 007 First Light marks an exciting new chapter for James Bond in games. In this project, BvSound, integrated into IO Interactive’s proprietary Glacier 2 engine, powers sound repositioning, diffraction, and reverb, delivering an immersive and realistic acoustic experience for players.
BvSound has become a PlayStation® Tools & Middleware partner, enabling game developers working on PlayStation® titles to evaluate and use our middleware. BvSound is now available in the Tools & Middleware Directory on SIE DevNet.
