An adaptive multiple position room response equalizer

The paper deals with an adaptive method for multiple position room response equalization. The proposed method works in the frequency domain. An adaptive estimation of the room responses at different positions is performed in the zone to be equalized and the common trend of these responses is extracted with efficient statistical operators. Then this prototype response is used to design the equalizer. The proposed approach is simple, computationally efficient and it is able to adapt to slow time variations in the room response.
