Methods for decoding a bit stream of audio multi-channel environment parametrico and to transmit digital data representing sound to a mobile unit, a decoder to decode a stream of parametrico immersive audio bit multi-channel environment parametrico, and.The mobile terminal a bit stream of audio envelope is received in a multichannel parametric multi-channel decoder (13).The parameters space received are in the unit of combination (37) transformed into a new set of spatial parameters that are used in order to obtain a decryption of the surrounding sound of multichannel is not a simple equivalent of the surrounding multichannel input signal originator Nal.But, for example, can be customized by the transformation based on a representation of filters connected to the head of the user obtained from a unit (43).Such parameters can also be obtained by combining personalized space parameters is received and a representation of spatial filters at the head of a user associated with a set of additional rendering parameters are determined interactively by e.g. The user and thus are dependent on time.
