Claim Text:
1. A device for generating an ambience signal suitable for being emitted via loudspeakers for which there is no suitable loudspeaker signal, comprising: a transient detector for detecting a transient period in which an examination signal comprises a transient region; a synthesis signal generator for generating a synthesis signal for the transient period, the synthesis signal generator being implemented to generate a synthesis signal which comprises flatter a temporal course than the examination signal in the transient period and the intensity of which deviates from an intensity of a preceding or subsequent portion of the examination signal by less than a predetermined threshold; and a signal substituter for substituting the examination signal in the transient period by the synthesis signal to obtain the ambience signal, wherein the device is additionally configured to generate signals for a left channel, a right channel and a center channel in a multichannel scenario, wherein the device further comprises an upmixer for generating signals for the left channel, the right channel and the center channel from a mono signal, a stereo signal or a representation of a parametrically encoded multichannel signal, and wherein the examination signal comprises the mono signal, the stereo signal, the multichannel signal, an already existing ambience signal or a synthesized ambience signal.
