Room Compensation using Multichannel Inverse Filters for Wave Field Synthesis Systems

Wave Field Synthesis is a 3D audio reproduction system, which allows synthesizing a realistic sound field in an extended area by using arrays of loudspeakers. However, the listening room introduces new echoes not present in the signal to be reproduced, reducing the spatial effect. This paper proposes a new correction approach based on obtaining direct solutions for the multichannel inverse filter bank in order to reduce the error in the listener area. Time and frequency domain algorithms will be proposed to calculate the bank of inverse filters. Different laboratory experiments have been carried out for validating the method.
