Abstract
A method of disassembling a pair of input signals L(t) and R(t) to form subband representations of N output channel signals o(t), o(t), . . . , o(t), wherein t is time. The method includes the steps of generating a subband representation of the signal L(t) containing a plurality of subband components L(t) where k is an integer ranging from 1 to M; generating a subband representation of the signal R(t) containing a plurality of subband components R(t); and constructing the subband representation for each of the plurality of output channel signals, each of those subband representations containing a plurality of subband components o(t), wherein o(t) represents the ksubband of the joutput channel signal and is constructed by combining components of the input signals L(t) and R(t) according to an output construction rule: o(t)=f(L(t),R(t)) for k=1, 2, . . . , M and j=1, 2, . . . , N.
