Abstract
The invention relates to a method for mixing a plurality of audio streams coded according to a frequency sub-band coding, comprising the steps for decoding (E) a part of the coded streams over at least a first frequency sub-band, for summing (E) the streams thus decoded so as to form at least a first mixed stream. The method is such that it comprises the steps for detection (E), over at least a second frequency sub-band different from the at least first sub-band, of the presence of a predetermined frequency band in the plurality of coded audio streams and for summing (E) the decoded audio streams (E) for which the presence of the predetermined frequency band has been detected, over said at least a second sub-band, so as to form at least a second mixed stream. The invention also relates to a mixing device implementing the method described and may be integrated into a conference bridge, a communications terminal or a communications gateway.
