Impulse

Impulse is Lese Audio Technologies' foray into easy, realistic & affordable acoustic simulation for everyone.

After 4 years of research & experimentation, the end result is the Impulse Engine, a scalable, multi-algorithm acoustic simulation system that's capable of any sort of reverb-related job with minimal work; We use it in real-time in our plugins like Eigen & Transfer, and now we are offering a piece of standalone software called... Impulse.

Impulse uses very large (or small) amounts of rays that get cast + processed in different ways to simulate sound propagation. It uses multiple types of ray-casting algorithms to do this, including ray tracing, ray inference, and beam tracing.

What is Impulse?

An Impulse Response Renderer: Every other reverb system just uses simple networks of delays to simulate reverberation in different spaces, some also use impulse responses (IRs) recorded in the real-world to simulate this. Impulse creates IRs out of digital spaces for you to use in convolution reverbs. Any space you can imagine, you can now hear.

Standalone Software: We realized very quickly that Impulse would be too much to work with in the constraints of what different plugin formats could offer. You can use it's computed impulse responses anywhere, though, and our plugin Eigen already has an Impulse-powered rendering system built-in.

Full Of Features:

Material Assignment: In Impulse, you can set any Acoustic material to any section of the scene that you want. Assignment is simplified to surfaces that make up larger sections (like walls), as opposed to treating the scene like conventional 3D geometry.

Preview Mode: Impulse features an "auralization" system for previewing how the acoustics might sound in your scene. Tweak any surface's material, change which source & listener you're using, and adjust other parameters, all in real time.

High Compatibility: Impulse handles all of the most common 3D model formats out of the box. Import standardized formats like .obj, .stl, and .fbx. You can even import many kinds of project files directly from other 3d modelling software, such as Blender & 3ds Max.

Pricing Models

Impulse is available as a one-time purchase, and also as different affordable subscription-based plans for short term projects. We can also offer organizational plans for universities and media studios.
