Interaction of a reproduction system with the listening room introduces distortions of the audio content. In this paper we present the key points that have to be addressed for compensating the listening room effect. The paper is focused on the particular situation of sound reproduction using Wave Field Synthesis (WFS). As a volume solution, WFS reproduces a given sound field in an extended area covering the whole listening room. Therefore, room compensation cannot be considered anymore for limited and discrete positions. The paper proposes solutions for achieving efficient treatment in an extended zone.
