Abstract :
This paper deals with a feedback delay network that has the feedback implemented with unitary matrix. The main contribution is the description of implementation of modified multi-layer feedback delay networks for computationally effective and high-quality multi-channel simulation of an auditory space. This new reverberation digital system is prepared for real-time processing and it meets the requirement for simulation with 8-channel output. This new system also provides a better control of simulation parameters that provides fine and accurate auditory space modeling than it has been common up to now with the perceptual approach to auditory space simulation.
