Next-generation spatial audio technology, grounded in physical modeling and designed for real-time immersive and interactive environments.
Real-Time,
Physically-Modeled
Spatial Audio
Outer Echo is a deep-tech audio startup focused on the simulation of spatial sound behavior—how sound propagates, interacts with environments, and evolves as listeners, sources, and obstacles move and rotate—for immersive and interactive applications.
Our practice sits at the intersection of:
> Physical modeling
> Real-time digital signal processing
> Spatial audio in immersive media and XR
Physical Modeling
At the core of our work is a strong emphasis on efficient physical modeling. We design algorithms that simulate wave phenomena, resonant structures, sound radiation, acoustic coupling, and spatial interactions with a focus on real-time use while attaining flexibility and sonic fidelity.
Through careful numerical design and stability analysis, perceptual optimization, and efficient implementation, we turn complex acoustic physical models into robust, low-latency spatial audio technologies suitable for rapid, iterative production environments.
Spatial Audio
At Outer Echo we specialize in immersive audio technologies that move beyond brute-force numerical simulations and static, impulse-like representations of space. Instead, we develop proprietary Physically-Modeled 6D Spatial Audio technology whereby real-time, interactive 6DOF simulation of complex acoustic environments flexibly integrates perceptual realism, physical consistency, efficiency, and low latency into a single framework.
Our 6D Spatial Audio technology relies on building a large-scale physical model of an acoustic scene defined from first principles, leading to navigable, runtime-editable virtual acoustic spaces where acoustic coupling and sound propagation manifest naturally.
Technology Output
Our physically-modeled 6D spatial audio rendering engine for real-time acoustic simulation of dynamic immersive environments, leveraging proprietary and patented technologies to achieve unprecedented levels of efficiency and flexibility
Outer Echo is based in Montréal and collaborates with partners at the intersection of audio technology, immersive media, and interactive systems.
