Abstract
The necessity of a large number of loudspeaker-microphone channels for the existing sound rendering systems complicates the application of multizone soundfield reproduction in reverberant environments. We introduce an adaptive reverberation cancelation method for multizone soundfield reproduction using sparse methods. The reproduced soundfield is described as a weighted series of orthonormal basis functions over the desired reproduction region, which is then used to adaptively equalize the desired multizone soundfield in terms of the basis function coefficients. The sparse methods result in a significantly reduced number of the required microphones for the measuring process of the reproduced soundfield. Simulation results verify the efficient room reverberation compensation for desired multizone soundfield reproduction. The proposed method also facilitates reproduction over a wide frequency range.
