Disclosed is a method of encoding a multichannel signal, such as a stereophonic audio signal, including at least a first signal component (L) and a second signal component (R). The method comprises the steps of transforming at least the first and second signal components by a predetermined transformation into a principal signal (y) including most of the signal energy and at least one residual signal (r) including less energy than the principal signal, the predetermined transformation being parameterised by at least one transformation parameter ((); and representing the multichannel signal at least by the principal signal and the transformation parameter. Further disclosed are a corresponding arrangement for encoding a multichannel signals and a corresponding method and arrangement for decoding such a signal.
