What GameSynth Runtime is

GameSynth Runtime is procedural audio middleware that creates sound effects in real time from patches made in the GameSynth authoring tool, shaped by parameters supplied by a game. Random parameter ranges let a patch produce varied sounds, while storing patch parameters rather than audio data can reduce memory use. Games can control synthesis through patch meta-parameters, and the runtime can send synthesis events back to the game.

Developers can call the API from C or C++ and customize memory allocation and file I/O. The runtime is optimized for each target platform, with controls to limit audio objects at patch level. It can run independently, use a platform’s native library or an engine audio subsystem, or pass audio buffers to Wwise, FMOD, or ADX2 voices. Unity and Unreal are supported engines; runtime targets include game consoles and embedded devices. GSBViewer previews exported binary models, allows meta-parameter adjustments, and displays API logs without code. Tsugi’s authoring tool includes procedural audio model editors and visual patching, and can also create wave files. Pricing is on request.

Who it suits

It suits game developers who want real-time procedural sound driven by game inputs, including teams using Unity or Unreal. Its middleware, native-library, and engine-subsystem options also suit projects with different audio integration needs.

What it does well

One patch can produce sound variations through random parameter ranges.
Games can adjust synthesis through meta-parameters and receive synthesis events.
C and C++ API supports memory allocation and file I/O customization.
Can connect with Wwise, FMOD, or ADX2 audio voices.
GSBViewer previews models and shows API logs without code.

What to know first

Pricing is available on request.
The maker says Runtime is not publicly available.
Runtime use is limited to project-specific versions through Tsugi's R&D services.

Limits

GameSynth Runtime is not publicly available; Tsugi says companies can contact it about project-specific versions through its R&D services. Pricing is on request.

Getting started

Visit the GameSynth Runtime website.
Contact Tsugi about a project-specific version through its R&D services.
Use the GameSynth authoring tool to create patches.
Integrate through C or C++, an engine audio subsystem, a target platform library, or supported middleware.

Verdict

Consider GameSynth Runtime if a game needs procedural sound generated in real time from game inputs, with options for engine, native-library, or middleware integration. Companies should contact Tsugi about project-specific access; teams seeking a publicly available product may need to look elsewhere.
