The present invention relates to a method and system for noise weight filtering. The method is comprised of the steps of receiving a signal comprising side information and an encoded signal, and decoding the encoded signal based on the side information and on a masking matrix. The step of decoding is comprised of the steps of separating the encoded signal into a set of n subband signal components, multiplying each subband signal component by a corresponding one of a set of n gain values to generate a corresponding one of a set of n multiplied subband signal components, the set of n gain values based on the masking matrix, and combining the n multiplied subband signal components to produce a decoded signal. The system is comprised of a receiver for receiving a signal comprising side information and an encoded signal, and a decoder for decoding the encoded signal based on the side information and on a masking matrix. The decoder is comprised of a unit for separating the encoded signal into a set of n subband signal components, a unit for multiplying each subband signal component by a corresponding one of a set of n gain values to generate a corresponding one of a set of n multiplied subband signal components, the set of n gain values based on the masking matrix, and a combiner for combining the n multiplied subband signal components to produce a decoded signal.
