Zusammenfassung:	THE PRESENT DOCUMENT RELATES TO AUDIO SIGNAL PROCESSING, IN PARTICULAR TO AN APPARATUS AND A CORRESPONDING METHOD FOR IMPROVING THE AUDIO SIGNAL OF AN FM STEREO RADIO RECEIVER. IN PARTICULAR, THE PRESENT DOCUMENT RELATES TO A METHOD AND SYSTEM FOR REDUCING THE NOISE OF A RECEIVED FM STEREO RADIO SIGNAL. AN APPARATUS (2) CONFIGURED TO REDUCE NOISE OF A RECEIVED MULTI- CHANNEL FM RADIO SIGNAL IS DESCRIBED, WHEREIN THE RECEIVED MULTI-CHANNEL FM RADIO SIGNAL IS REPRESENTABLE AS A RECEIVED MID SIGNAL AND A RECEIVED SIDE SIGNAL. THE APPARATUS (2) COMPRISES A PARAMETER DETERMINATION UNIT (77) CONFIGURED TO DETERMINE ONE OR MORE PARAMETERS INDICATIVE OF A CORRELATION AND/OR DECORRELATION BETWEEN THE RECEIVED MID SIGNAL AND THE RECEIVED SIDE SIGNAL; AND A NOISE REDUCTION UNIT (79) CONFIGURED TO GENERATE A NOISE-REDUCED SIDE SIGNAL FROM THE RECEIVED MID SIGNAL AND NOT FROM THE RECEIVED SIDE SIGNAL USING THE ONE OR MORE PARAMETERS.
