摘要：Disclosed is a method of encoding a multichannel signal, such as a stereophonicaudio 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 andsecond 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 lessenergy than the principal signal, the predetermined transformation being parameterisedby at least one transformation parameter ((); and representing the multichannel signal atleast by the principal signal and the transformation parameter. Further disclosed are acorresponding arrangement for encoding a multichannel signals and a correspondingmethod and arrangement for decoding such a signal.
