摘要:
An apparatus for generating a stereo side signal having a first side channel and a second side channel from a stereo input signal having a first input channel and a second input channel is provided. The apparatus comprises a modification information generator (110) for generating modification information based on mid-side information. Furthermore, the apparatus comprises a signal manipulator (120) being adapted to manipulate the first input channel based on the modification information to obtain the first side channel and being adapted to manipulate the second input channel based on the modification information to obtain the second side channel. The modification information generator (110) comprises a spectral subtractor (115) for generating the modification information by generating a difference value indicating a difference between a mono mid signal or a mono side signal of the stereo input signal and the first or the second input channel.

An apparatus (100) for generating a multi-channel audio signal (142) based on an input audio signal (102) comprises a main signal upmixing means (110), a section selector (120), a section signal upmixing means (110) and a combiner (140). The main signal upmixing means (110) is configured to provide a main multi-channel audio signal (112) based on the input audio signal (102). The section selector (120) is configured to select or not select a section of the input audio signal (102) based on an analysis of the input audio signal (102). The selected section of the input audio signal (102), a processed selected section of the input audio signal (102) or a reference signal associated with the selected section of the input audio signal (102) is provided as section signal (122). The section signal upmixing means (130) is configured to provide a section upmix signal (132) based on the section signal (122), and the combiner (140) is configured to overlay the main multi-channel audio signal (112) and the section upmix signal (132) to obtain the multi-channel audio signal (142).

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.
