Formal subjective tests of real-time room dereverberation using Complex Smoothing were conducted to assess the robustness and the validity of the method under real sound reproduction conditions. For comparison, anechoic, inverse loudspeaker real-time filtering was also subjected to assessment to decouple improvements due to the complex smoothing inverse room filtering and due to mere equalization of the loudspeakers. Results derived from a multivariate analysis of variance (MANOVA) of the test data, verify the conclusions detected in the past by the objective evaluation of the method e.g. significant improvement in sound quality and immunity to real-time processing artifacts independently of room size and listener position.
