Abstract
Digital methods for creating artificial reverberation have been investigated for more than 50 years, starting with digital all-pass filters. Later development led to the Feedback Delay Network approach which is considered as a state-of-the-art artificial reverberation. However, research has mostly focused on simulating a single room’s impulse response while coupled room acoustics have lacked investigation. This project focuses on designing a real-time implemented plugin for simulating coupled room acoustics through Feedback Delay Networks. Furthermore, the plugin allows for remote control of parameters with the Open Sound Control protocol. Different evaluation methods for subjective and objective evaluation are proposed for the plugin. Although technical limitations resulted in the implementation of only single Feedback Delay Network, the plugin can be used for research purposes by comparing offline rendered reverberation to its real-time implemented counterpart.
