摘要：
An apparatus for generating a stereo output signal comprises a manipulation information generator (110; 210; 340; 440; 640) being adapted to generate manipulation information depending on a first signal indication value of a first input channel and on a second signal indication value of a second input channel, and a manipulator (120; 220; 360, 370; 460, 470; 660, 670) for manipulating a combination signal based on the manipulation information to obtain a first manipulated signal as a first output channel and a second manipulated signal as a second output channel. The combination signal is a signal derived by combining the first input channel and the second input channel. Furthermore, the manipulator (120; 220; 360, 370; 460, 470; 660, 670) is configured for manipulating the combination signal in a first manner, when the first signal indication value is in a first relation to the second signal indication value, or in a different second manner, when the first signal indication value is in a different second relation to the second signal indication value.
