10.4 Reproduction using different rendering setups

Given the spatial decomposition of the stereo signal, i.e. the sub-band signals for the estimated localized direct sound ŝ′m, the factor Ab, and the lateral independent signals n1,m and images2,m, one can define rules on how to emit the signal components corresponding to ŝ′m, images1,m, and images2,m from different playback setups.

10.4.1 Multiple loudspeakers in front of the listener

Figure 10.8 illustrates the scenario that is addressed. The virtual sound stage of width ϕ0 = 30°, shown in Part (a) of the figure, is scaled to a virtual sound stage of width ϕ0 which is reproduced with multiple loudspeakers, shown in part (b) of the figure.

Figure 10.8 The ±30° virtual sound stage (a) is converted to a virtual sound stage with the width of the aperture of a loudspeaker array (b).

The estimated independent lateral sound, images1,m and images2,m, is emitted from the ...
