摘要：
A method of decomposing a multichannel audio signal is described. The method includes, for each of a plurality of frequency components of a segment in time of the multichannel audio signal, calculating a corresponding indication of a direction of arrival. The method also includes, based on the calculated direction indications, selecting a subset of the plurality of frequency components. The method further includes, based on the selected subset and on a plurality of basis functions, calculating a vector of activation coefficients. Each activation coefficient of the vector corresponds to a different basis function of the plurality of basis functions.
