Abstract
There is described a method of encoding input signals (CHI to CHto) in a multi-channel encoder () to generate corresponding output data comprising down-mix output signals () together with complementary parametric data (). The method includes a first step of down-mixing input signals (CHI to CHto) to generate the corresponding down-mix output signals (), and a second step of processing the input signals (CHI to CHto) during down-mixing to generate said parametric data () complementary to the down-mix output signals (). Processing of the input signals (CHI to CHto) involves including information in the down-mix signals () which is useable during subsequent decoding of the down-mix output signals () and the parametric data () to determine at least some parameter data and thereby enabling representations of the input signals (CHI to CHto) to be subsequently regenerated. Coders for use in the encoder () for performing essential signal processing operations therein are also elucidated.
