Patent ID: 8731209

Claim:
A device for generating a multi-channel signal comprising a number of output channel signals greater than a number of input channel signals of an input signal, the number of the input channel signals equaling one or greater, comprising: an upmixer arranged to upmix the input signal including a speech portion in order to provide at least a direct channel signal and at least an ambience channel signal including the speech portion; a speech detector arranged to detect the speech portion in a section of the input signal, the direct channel signal provided by the upmixer or the ambience channel signal provided by the upmixer; a signal modifier arranged to modify a section of the ambience channel signal which corresponds to that section having been detected by the speech detector in order to acquire a modified ambience channel signal in which the speech portion is attenuated or eliminated, the section in the direct channel signal being attenuated to a lesser extent or being not attenuated; and a loudspeaker signal output device arranged to output loudspeaker signals in a reproduction scheme using the direct channel signal and the modified ambience channel signal, the loudspeaker signals being the output channel signals.
