Claim 4:
5. The method according to claim 1, comprising, for a given audio element in the cluster among the plurality of clusters:
determining measures of correlation between the given audio element and any of the plurality of audio elements;
determining a third measure of energy for the given audio element as a weighted sum of the measures of energy that the audio elements contribute to the cluster, wherein the weights for the measures of energy are based on the respective measures of correlation between the respective audio elements and the given audio element;
determining a fourth measure of energy for the given audio element as a weighted sum, over any audio elements among the plurality of audio elements apart from the given audio element, of geometric means of the measure of energy that the given audio element contributes to the cluster and respective measures of energy that the audio elements among the plurality of audio elements apart from the given audio element contribute to the cluster, wherein the weights for the geometric means are based on the respective measures of correlation between the respective audio elements and the given audio element; and
determining, as at least a part of the compensation gain for the given audio element, an individual compensation gain of the given audio element based on the third measure of energy and the fourth measure of energy.
