    • An apparatus for mapping a first input channel and a second input channel of an input channel configuration to at least one output channel of an output channel configuration, wherein each input channel and each output channel has a direction in which an associated loudspeaker is located relative to a central listener position, wherein the apparatus is configured to map the first input channel to a first output channel of the output channel configuration. The apparatus is further configured to at least one of a) map the second input channel to the first output channel, comprising processing the second input channel by applying at least one of an equalization filter and a decorrelation filter to the second input channel, and b) despite of the fact that an angle deviation between a direction of the second input channel and a direction of the first output channel is less than an angle deviation between a direction of the second input channel and the second output channel and/or is less than an angle deviation between the direction of the second input channel and the direction of the third output channel, map the second input channel to the second and third output channels by panning between the second and third output channels.
    • 用于映射的第一输入通道和输入通道配置中的输出信道配置的至少一个输出信道的第二输入信道,worin各输入通道和各输出信道的装置,具有在其中相关联的扬声器位于相对于一个方向 中央听众位置,worin所述装置被配置为将所述第一输入信道映射到所述输出信道配置的第一输出通道。 该装置进一步被配置为的至少一种)映射第二输入通道到所述第一输出通道,包括通过施加均衡滤波器中的至少一个和一个解相关滤波器的第二输入通道,以及b处理所述第二输入通道 ),尽管角度偏差的第二输入信道的一个方向和所述第一输出通道的方向之间的factthat的是小于在第二输入信道的一个方向和所述第二输出通道之间和/或角的偏差为小于 到第二输入通道的方向和第三输出通道的方向之间的角度偏差,通过在第二和第三输出通道之间平移映射第二输入信道到第二和第三输出通道。
