As Fraunhofer IDMT wanted to develop MCR (Multiple Channel amplification of Reverberation) on their digital audio platform, I was requested to support them with the development. At their research facility in Ilmenau the principle of MCR was explained as also how to set-up MCR on a digital platform and how to tune a MCR system. In a demo room a set-up of a system was made. With this system functions were tested, functions changed and/or added and also the tuning procedure was demonstrated. With the support provided Fraunhofer IDMT was made capable to further develop MCR on their platform.
