发明名称 Control of a conference call
摘要 <p>A method and an apparatus for controlling a conference call is a system which comprises a conference bridge for combining several audio signals arriving from terminals and for transmitting the combined signal further to at least one of the terminals using at least one transmitting codec. The conference bridge comprises a spatialization unit for creating a spatial effect. The number of simultaneously active audio components, such as speech signals, is determined from the audio signals of the conference bridge inputs. At least one transmitting codec is selected for use on the basis of the number of simultaneously active audio components and the combined signal is transmitted to at least one terminal using the selected transmitting codec. &lt;IMAGE&gt;</p>
