A method of generating a monaural signal (S) includes a combination of at least two input audio channels (L, R). Corresponding frequency components from respective frequency spectrum representations for each audio channel (L(k), R(k)) are summed to provide a set of summed frequency components (S(k)) for each sequential segment. For each frequency band (i) of each of sequential segment, a correction factor (m(i)) is calculated as function of a sum of energy of the frequency components of the summed signal in the band.di-elect cons..times..function. ##EQU00001## and a sum of the energy of the frequency components of the input audio channels in the band.di-elect cons..times..function..function. ##EQU00002## Each summed frequency component is corrected as a function of the correction factor (m(i)) for the frequency band of the component.
