Abstract:
A rendering system including a plurality of loudspeakers, at least one microphone and a signal processing unit. The signal processing unit is configured to determine at least some components of a loudspeaker-enclosure-microphone transfer function matrix estimate describing acoustic paths between the plurality of loudspeakers and the at least one microphone using a rendering filters transfer function matrix using which a number of virtual sources is reproduced with the plurality of loudspeakers.

Claim (Index 9):
The rendering system according to  claim 6 , wherein the signal processing unit is configured to update at least some components of the loudspeaker-enclosure-microphone transfer function matrix estimate based on the distributedly evaluated equation\n \u0124 (\u03ba|\u03ba\u22121)= \u0124 (\u03ba\u22121|\u03ba\u22122)+ \u0124 S \u0394 (\u03ba\u22121) H D + (\u03ba\u22121) as part of an initialization of a following interval's estimated source-specific transfer function matrix by\n \u0124 S (\u03ba+1|\u03ba)=( \u0124 (\u03ba\u22121|\u03ba\u22122)+ \u0124 S \u0394 (\u03ba\u22121) H D + (\u03ba\u22121)) H D (\u03ba+1)+ \u0124 S \u0394 (\u03ba) H T (\u03ba,\u03ba+1)  \n in order to reduce a peak load of the signal processing unit;\n wherein \u03ba\u22122 denotes a second previous time interval, wherein \u03ba\u22121 denotes a previous time interval, wherein \u03ba denotes a current time interval, wherein \u03ba+1 denotes a following time interval, wherein between the time intervals at least one out of a number of virtual sources and a position of at least one of the virtual sources is changed, wherein \u0124(\u03ba|\u03ba\u22121) represents a loudspeaker-enclosure-microphone transfer function matrix estimate, \u0124 S (\u03ba+1|\u03ba) represents an estimated source-specific transfer function matrix, wherein \u0124(\u03ba\u22121|\u03ba\u22122) represents a loudspeaker-enclosure-microphone transfer function matrix estimate, wherein \u0124 S \u0394 (\u03ba\u22121) represents an update of an estimated source-specific transfer function matrix, H D + (\u03ba\u22121) represents an inverse rendering filters transfer function matrix, H D (\u03ba+1) represents a rendering filters transfer function matrix, \u0124 S \u0394 (\u03ba) represents an update of an estimated source-specific transfer function matrix, and wherein H T (\u03ba,\u03ba+1)  represents a transition transform matrix which describes an update of an estimated source-specific transfer function matrix of the current time interval to the following time interval, such that only a contribution of is \u0124 S \u0394 (\u03ba)H T (\u03ba,\u03ba+1)  is computed between two time intervals.
