Lese Eigen - Reflection Processing Multitool

Lese Eigen is a reflection processing multi-tool for simulating acoustic spaces, creating reverb impulse responses, and analyzing room resonances. Built around Lese's Impulse Engine, Eigen combines three distinct modes: Play, Render, and Analyze.

Play mode provides accurate real-time early reflection processing with adjustable source and listener positions, reflection depth, room dimensions, and spatial settings. Render mode generates high-quality reverb impulse responses using customizable room dimensions and acoustic materials, including frequency-dependent material processing and late reflections. The resulting impulse responses can be saved for use in external convolution reverbs or directly within Eigen.

Analyze mode provides room mode analysis to examine how a virtual space responds to low-frequency energy, making it useful for understanding room resonances based on specific dimensions.
