Different objective measurements are known to rate the spatial quality of concert halls. Many measures are based on analyzing the binaural impulse responses. In this paper, we will compare different algorithms for artificial reverberation in terms of these measures.The tested algorithms are commercially available devices and digital plug-ins in a broad price range. For the analysis, we programmed an analysis toolbox which contains several binaural analysis methods, including the interaural cross-correlation and the interaural difference. Furthermore, less known measures, modifications, and new techniques will be presented. The results indicate that objective measures can give some first impression of the spatial quality of reverberation devices.
