Eigen: Reflection Processing Multitool by Lese Free Download

The main Play mode lets you place the sound source and listener on a multidimensional object positioner. Drag along one of three axes and switch the active axis with the selector on the right, or use a more conventional set of dimension sliders instead.

Early reflections are processed up to seven reflections deep, with acoustic bouncing simulation. A sound propagation toggle removes the initial delay from both early reflection processing and the high-quality render system. Play mode can run in mono, stereo, or ambisonic settings at low or high quality, which covers both simple background effects and higher-fidelity spatial audio.

Render mode creates high-quality reverb impulse responses using your dimension and material settings. You can set the reflection depth, enable material processing, and add late reflections. Early reflections can be rendered up to 40 bounces deep in this offline mode.

Lese says the High Quality Materials setting splits each reflection into ten frequency bands and processes them against measured real-world material responses. Because this is too heavy for real-time use, the results are rendered as impulse responses. You can preview them with the Convolution toggle and save them for use in other convolution reverbs.
