摘要： Aspects of the invention provide methods, computer-readable media, and apparatuses for re-panning multiple audio signals by applying spatial cue coding. Sound sources in each of the signals may be re-panned before the signals are mixed to a combined signal. Processing may be applied in a conference bridge that receives two omni-directionally recorded audio signals. The conference bridge subsequently re-pans one of the signals to the listeners left side and the signal to the right side. The source image mapping and panning may further be adaptively based on the content and use case. Mapping may be done by manipulating the directional parameters prior to directional decoding or before directional mixing. Directional information that is associated with an audio input signal is remapped order to compress input source positions into virtual source positions. The virtual sources may be placed with respect to actual loudspeakers using binaural cue panning.

摘要： 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.
