Abstract (en)
[origin: WO2011009649A1] The proposed device or proposed method enable the linear variation of the degree of correlation, in particular of pseudo-stereophonic audio signals, and overall, offer a comprehensive but very simple post-processing option. This is desirable in telephony, for example, which to this day is almost entirely based on a mono signal, in the field of the professional post-processing of audio signals, in particular for the limitation or expansion of the source width thereof, for obtaining stable FM stereo signals, or further in the area of premium electronic consumer goods, which aim for the simplest, most efficient operation.
