Building Next-Gen Audio: The Technical Foundation of SweejTech

At SweejTech, we're building our audio DSP stack from the ground up to take full advantage of modern hardware capabilities. Here’s the thinking behind some of the technology we’re working on.

Foundation First: The Math Library

At the core of SweejTech is a custom-built audio specific DSP mathematics library. While many solutions build directly on more general-purpose game engine math libraries, we've developed a platform-agnostic foundation that allows for precise control over performance-critical operations. Audio processing demands consistent, fast and predictable performance - requirements that shaped our mathematical foundation from day one.

Rethinking Reverb for Modern Hardware

One area where this foundation proves crucial is in our convolution reverb implementation. Modern game engines haven’t taken full advantage of the performance capabilities of modern hardware in their convolution implementations, resulting in restrictions on reverb usage due to CPU constraints. We're challenging this limitation.

By rethinking how data is stored and processed, we've achieved significant performance gains. This means games can use more reverb instances in more contexts than previously allowed for, opening new possibilities for sound designers.

Cross-Platform Performance

A key challenge in game audio is maintaining consistent performance and signal output across different platforms. Our technology is designed to deliver identical results whether running on a PS5, high-end PC, or Xbox Series. This predictability is crucial for game developers who need to ensure consistent audio quality across their entire player base.

Looking Forward

Future developments include exploring real-time acoustic simulation and advanced binaural rendering. While these features are still in development, they represent our commitment to pushing the boundaries of what's possible in game audio.

By building our technology stack from first principles, we're creating solutions that don't just work within current constraints, but help define what's possible for the next generation of game audio.
