摘要： 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.

摘要： A transient detector is provided for generating an ambience signal suitable for being emitted via loudspeakers for which there is no special loudspeaker signal to detect a transient period. A synthesis signal generator produces a synthesis signal which fulfils the transient condition on the one hand and the continuity condition for the synthesis signal on the other hand. A signal substituter will then substitute a portion of the examination signal by the synthesis signal to obtain an ambience signal for the surround channels.

摘要： For synthesizing at least three output channels using two stereo input channels, the stereo input channels are analyzed to detect signal components occurring in both input channels. A signal generator is operative to introduce at least a part of the detected signal components into the second channel associated with a second speaker in an intended speaker scheme, which is positioned between a first and a third speaker in the speaker scheme. When, however, feeding of the complete detected signal components would result in a clipping situation, then only a part of the detected signal components is fed into the second channel as a real center channel and the remainder is located in the first and third channels as a phantom center channel.
