A method for reducing data during the transmission and/or storage of the digital signals of several dependent channels is described. The dependence of the signals in the channels, e.g. in a left and a right stereo channel, can be used for an additional data reduction. Known methods such as middle/side encoding or the intensity stereo process lead to perceptible interference in the case of an unfavourable signal composition. The method according to the invention avoids such interference, in that a common encoding of the channels only takes place if there is an adequate spectral similarity of the signals in the two channels. With the aid of the method according to the invention an additional data reduction can be achieved in that in those frequency ranges where the spectral energy of a channel does not exceed a predeterminable fraction of the total spectral energy, the associated spectral values are set at zero. As the method is independent of the specific internal form of the encoding method, it is universally usable.
