Abstract
In a method of encoding input signals (CHto CHto) in a multi-channel encoder () to generate corresponding output data having down-mix output signals () together with complementary parametric data (), the method includes a first step of down-mixing input signals (CHto CHto) to generate the corresponding down-mix output signals (), and a second step of processing the input signals (CHto CHto) during down-mixing to generate the parametric data () complementary to the down-mix output signals (). Processing of the input signals (CHto 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 (CHto CHto) to be subsequently regenerated.
