Convention Paper

Constant Complexity Reverberation for Any Reverberation Time

Authors: May, Tobias; Schobben, Daniël

AES Convention 122 · Paper 7040 · May 2007

Abstract

A new artificial reverberation system is proposed which is based on perceptually relevant components in reverberated audio and as such allows for a very efficient implementation. The system first separates the signal into transient and steady-state components. The transient signal is reverberated by using an efficient time-varying recursive filter while the steady-state signal is processed separately with an all-pass filter. In contrast to common reverberation systems, the complexity of the recursive filter is determined solely by the duration of the transients and is therefore independent of the reverberation time.
