Genetic Material Optimizer

The Genetic Material Optimizer is a tool for modifying materials in the room in order to match simulated room acoustic parameters to measured ones. This is very useful when an existing room needs to be improved acoustically using simulations, while the real materials are not completely known. Using this tool makes it possible to “calibrate” the ODEON model to the real one.
