Abstract (en)
[origin: WO2007078254A2] A parametric multi-channel surround audio bitstream is received in a multi-channel decoder (13). The received spatial parameters are in combining unit (37) transformed into a new set of spatial parameters that are used in order to obtain a decoding of the multi-channel surround sound that is not a simple equivalent of the original input multi-channel surround signal but e.g. may be personalized by making the transformation based on a representation of user head related filters obtained from a unit (43). Such personalized spatial parameters may also be obtained by combining the received spatial parameters and a representation of the user head related filters with a set of additional rendering parameters that for example are interactively determined by the user and thus are time dependent.
