Impulse is a standalone acoustic simulation system that delivers high-quality impulse responses for convolution reverbs. Developed after four years of research, it uses advanced ray-casting algorithms including ray tracing, ray inference, and beam tracing to accurately simulate sound propagation in digital spaces. This approach surpasses traditional reverb methods that rely on simple delay networks or pre-recorded impulse responses, enabling users to create custom reverberation tailored to any imagined environment.

Designed to handle complex acoustic modeling beyond the limitations of plugin formats, Impulse offers material assignment features that let users define acoustic properties on large surface areas such as walls, streamlining the simulation process. Its integrated auralization preview system allows real-time listening while adjusting source positions, listener settings, and surface materials, providing immediate feedback on acoustic changes. The software supports a wide range of common 3D file formats including .obj, .stl, and .fbx, making it compatible with popular modeling tools like Blender and 3ds Max.

Impulse is available through one-time purchase or subscription plans tailored for various project durations, as well as organizational options for academic institutions and media studios. Its impulse responses are fully exportable for use in other convolution reverbs or integrated into plugins like Eigen, which already includes an Impulse-based rendering engine. This combination of advanced simulation, flexible usage, and broad compatibility makes Impulse a powerful tool for sound designers seeking precise acoustic environments.
