Disclosed is a method for decoding M encoded audio channels representing N audio channels, where N is two or more and M is two or more, and a set of one or more spatial parameters. The method comprises receiving said M encoded audio channels and said set of spatial parameters, deriving N audio channels from said M encoded channels, wherein an audio signal in each audio channel is divided into a plurality of frequency bands, wherein each band comprises one or more spectral components, and generating a multichannel output signal from the N audio channels and the spatial parameters. The set of spatial parameters includes a first parameter indicative of the amount of an uncorrelated signal to mix with a derived audio channel. The generating a multichannel output signal includes controlling the proportion of correlated to uncorrelated signal in at least one of the N audio channels in response to one or ones of said spatial parameters, wherein said controlling is at least partly in accordance with said first parameter. |
