Vorrichtung und Verfahren zum Erzeugen eines Multikanalsignals mit einer Sprachsignalverarbeitung

DE 102007048973 A1 UPAB: 20090509 NOVELTY - The device has output channels, and a high mixer (14) for high mixing of an input signal (12) to supply to a direct channel (15), an adjacent channel (16) or a modified adjacent channel (16'). A signal modifier (20) modifies a section of the channel (16) or the input signal, that corresponds to a section detected by a speech detector (18), to obtain a modified adjacent signal channel (21) or a modified input signal, in which a speech portion is eliminated. A loudspeaker signal output unit (22) outputs loudspeaker signals in a rendition pattern using the direct and modified adjacent channels. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for producing a multi-channel signal with a number of output channels (2) a computer program with a program for implementing a method for producing a multi-channel signal. USE - Device for producing a multi-channel audio signal for a DVD. ADVANTAGE - The device is designed such that the multi-channel audio signals are produced with the number of output channels with a high quality in a flexible manner, and a reproduction of speech components in rear channels and/or the adjacent signal channel that disturbs a listener is prevented
