    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: Techniques for positioning participants of a conference call in a three dimensional (3D) audio space are described. Aspects of a system for positioning include a client component that extracts speech frames of a currently speaking participant of a conference call from a transmission signal. A speech analysis component determines a voice fingerprint of the currently speaking participant based upon any of a number of factors, such as a pitch value of the participant. A control component determines a category position of the currently speaking participant in a three dimensional audio space based upon the voice fingerprint. An audio engine outputs audio signals of the speech frame based upon the determined category position of the currently speaking participant. The category position of one or more participants may be changed as new participants are added to the conference call.

    摘要: A method for distinguishing speakers in a conference call of a plurality of participants, in which method speech frames of the conference call are received in a receiving unit, which speech frames include encoded speech parameters. At least one parameter of the received speech frames is examined in an audio codec of the receiving unit, and the speech frames are classified to belong to one of the participants, the classification being carried out according to differences in the examined at least one speech parameter. These functions may be carried out in a speaker identification block, which is applicable in various positions of a teleconferencing processing chain. Finally, a spatialization effect is created in a terminal reproducing the audio signal according to notified differences by placing the participants at distinct positions in an acoustical space of the audio signal.
