    • In order to generate a multi-channel signal having a number of output channels greater than a number of input channels, a mixer is used for upmixing the input signal to form at least a direct channel signal and at least an ambience channel signal. A speech detector is provided for detecting a section of the input signal, the direct channel signal or the ambience channel signal in which speech portions occur. Based on this detection, a signal modifier modifies the input signal or the ambience channel signal in order to attenuate speech portions in the ambience channel signal, whereas such speech portions in the direct channel signal are attenuated to a lesser extent or not at all. A loudspeaker signal outputter then maps the direct channel signals and the ambience channel signals to loudspeaker signals which are associated to a defined reproduction scheme, such as, for example, a 5.1 scheme.
    • 为了产生具有大于多个输入通道的输出通道数量的多通道信号,混频器用于将输入信号上混合以形成至少直接信道信号和至少一个环境信道信号。 提供语音检测器,用于检测语音部分发生的输入信号,直接信道信号或环境信道信号的一部分。 基于该检测,信号修改器修改输入信号或环境信道信号,以便衰减环境信道信号中的语音部分,而直接信道信号中的这种语音部分被衰减到较小程度,或根本不被衰减。 然后,扬声器信号输出器将直接信道信号和环境信道信号映射到与所定义的再现方案(例如5.1方案)相关联的扬声器信号。
