Room correction methods are commonplace in the home audio-video equipment. One goal of these systems is to correct frequency deviation of loudspeaker/room response from some desired target curve. Unfortunately this frequency correction may be appropriate only in small area around the microphone location. Some room correction algorithms capture the room responses at multiple locations and combine them to obtain a representative response used for frequency correction. We will present a loudspeaker / room correction system that achieves perceptually appropriate frequency correction in a wide listening area by using closely spaced non-coincident multi-microphone structure placed in a single location in the room. By use of special probing signals we achieve our goal within short measurement period.
