The invention relates to a method of generating a left modified and a right modified audio signal for a stereo system from multichannel audio signals (X.sub.L, X.sub.R, X.sub.LS, X.sub.RS, and X.sub.C) with a left and a right channel and at least one further audio channel. According to the invention, the signal of the channel of highest energy is modified in a filter (1) with a transformation function in a first parallel branch (2) and is modified in a second filter (6) with a reverberation function in a second parallel branch (5), whereupon the modified signals are joined together in a summation unit (8).
