This residual signal is transmitted (18) together with one or more multi-channel parameters (14) to a decoder. In contrast to a purely parametric multi-channel decoder, the enhanced decoder generates a multi-channel output signal having an improved output quality because of the additional residual signal.en621006patent2005065521620050080775
