At least one stereo audio spectrum value of the scale factor band by intensity stereo process. The left channel includes the coded stereo audio spectrum value by intensity stereo processes and the right channel includes the stereo audio spectrum, which almost has zero value. When an intensity stereo coding is active in a section composed of scaling factor bands (28), prediction for the right channel (R) is deactivated in this area, so that the prediction results are not used to build the coded stereophonic spectral values. The predictor of the right channel (R) is supplied with stereophonic spectral values for this channel which are in turn decoded by an intensity stereo process, so that prediction for the right channel (R) can continue to adapt itself.
