Abstract
A control section () receives signaling (S) indicating one of at least two coding formats (F, F, F) of an M-channel audio signal (L, LS, LB, TFL, TBL), the coding formats corresponding to different partitions of the channels of the audio signal into respective first and second groups (), wherein, in the indicated coding format, first and second channels (L, L) of a downmix signal correspond to linear combinations of the first and second groups, respectively; and a decoding section () reconstructs the audio signal based on the downmix signal and associated upmix parameters (α). In the decoding section: a decorrelation input signal (D, D, D) is determined based on the downmix signal and the indicated coding format; and wet and dry upmix coefficients, controlling linear mappings of the downmix signal and a decorrelated signal, generated based on the decorrelation input signal, are determined based on the upmix parameters and the indicated coding format.
