Abstract
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.
