Claim 18:
19. A method for encoding a multichannel signal, the method comprising:
downmixing the multichannel signal to acquire a downmix signal, wherein the downmixing comprises active downmixing or passive downmixing;
encoding the downmix signal, wherein the downmix signal comprises a low band and a high band, wherein the encoding the downmix signal comprises applying a bandwidth extension processing for parametrically encoding the high band;
generating a spectral representation of the multichannel signal; and
processing the spectral representation comprising the low band and the high band of the multichannel signal to generate multichannel information.
