In a method for eliminating voice signals from a stereo input signal stream a monophonic and a stereophonic signal stream is derived by adding ( 3 ) and subtracting, ( 4 ) respectively, the left and right signal content of the stereo input signal stream, where after the monophonic signal stream is filtered by means of a band stop filter device ( 5 ), and a stereo output signal stream is obtained by adding ( 6 ) the stereophonic signal stream and the filtered monophonic signal stream, and subtracting ( 7 ) the stereophonic signal stream and the filtered monophonic signal stream, respectively. The method may be applied for voice suppression in karaoke applications.
