An apparatus for calculating driving coefficients for loudspeakers of a loudspeaker arrangement for an audio signal associated with a virtual source comprises a multi-channel renderer. The multi-channel renderer (510) calculates driving coefficients (512) for loudspeakers (550) of the loudspeaker arrangement based on a first calculation rule, if a position (502) of the virtual source is located outside the loudspeaker transition zone (530). Further, the multi-channel renderer (510) calculates driving coefficients (512) for loudspeakers (550) of the loudspeaker arrangement based on a second calculation rule, if a position (502) of the virtual source is located within the loudspeaker transition zone (530). A border of the loudspeaker transition zone (530) comprises a minimal distance to a loudspeaker (550) of the loudspeaker arrangement depending on a distance between the loudspeaker (550) and a loudspeaker (550) adjacent to this loudspeaker (550). Further, the loudspeaker arrangement comprises at least two pairs of adjacent loudspeakers (550) with different distances between the loudspeakers (550) of the respective pair of loudspeakers (550). |
