An apparatus for generating a stereo output signal includes a manipulation information generator 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 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 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.

Apparatus and method and computer program for generating a stereo output signal for providing additional output channels

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 has a modification information generator for generating modification information based on mid-side information. Furthermore, the apparatus has a signal manipulator 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 has a spectral weights generator for generating the modification information by generating a first spectral weighting factor based on a mono mid signal and on a mono side signal of the stereo input signal.

Method and apparatus for decomposing a stereo recording using frequency-domain processing employing a spectral weights generator

A vehicle includes a side wall, a ceiling and a speaker arrangement including at least one speaker. The speaker arrangement is positioned in or at the side wall and is configured such that a main sound emission direction of the speaker arrangement is directed to the ceiling.

An apparatus for generating a multi-channel audio signal based on an input audio signal comprises a main signal upmixer, a section selector, a section signal upmixer and a combiner. The main signal upmixer is configured to provide a main multi-channel audio signal based on the input audio signal. The section selector is configured to select or not select a section of the input audio signal based on an analysis of the input audio signal. The selected section of the input audio signal, a processed selected section of the input audio signal or a reference signal associated with the selected section of the input audio signal is provided as section signal. The section signal upmixer is configured to provide a section upmix signal based on the section signal, and the combiner is configured to overlay the main multi-channel audio signal and the section upmix signal to obtain the multi-channel audio signal.
