Multizone soundfield reproduction over an extended spatial region is a challenging problem in acoustic signal processing. We introduce a method of reproducing a multizone soundfield within a desired region in reverberant environments. It is based on the identification of the acoustic transfer function (ATF) from the loudspeaker over the desired reproduction region using a limited number of microphone measurements. We assume that the soundfield is sparse in the domain of planewave decomposition… CONTINUE READING
