Convolution reverberation is an excellent method for generating high-quality artificial reverberation that accurately portrays a specific space, but it can only represent the static listener and source positions of the measured impulse response being convolved. In this paper, multiple measured impulse responses along with interpolated impulse responses between measured locations are convolved with dry input audio to create the illusion of a moving source. The computational cost is decreased by using a hybrid approach to reverberation which recreates the early reflections through convolution with a truncated impulse response while the late reverberation is simulated with a feedback delay network.
