In this paper a comparison of different algorithms for artificial reverberation is be presented. The tested algorithms are commercially available devices and digital plug-ins in a broad price range plus algorithms known from literature. For the analysis we developed an analysis toolbox, which contains several monaural analysis methods, including the energy decay curve in fractional octave bands, auto-correlation, and other known measures of reverberation qualities. Furthermore, the behaviour over time will be analyzed, showing that many systems cannot be considered as time-invariant. Some statistical analysis of the impulse response will also be given. The purpose is to investigate whether synthetic reverberation is created pertaining to attributes of real rooms and whether there are differences between algorithms or not.
