    • A method of audio scene management in a teleconference or other group sound telecommunication is presented, in which teleconference at least a first transmitting party, a second transmitting party and a receiving party participates. The method comprises receiving (210) of signals representing sound of the first transmitting party and sound of the second transmitting party. The method further comprises obtaining (212) of measures of sound activity for the first and second transmitting parties, respectively and selecting (214) a first angle and/ or a second angle based on the obtained measures of sound activity. The method further comprises processing (216) of the received signals into processed signals such that sound from the first transmitting party is experienced by the receiving party as emanating from the first angle while sound from the second transmitting party is experienced as emanating from the second angle, with respect to the receiving party. Finally signals representing the processed signals are outputted (218).
    • 提出了电话会议或其他组声音通信中的音频场景管理的方法,其中至少第一发送方,第二发送方和接收方的电话会议参与。 该方法包括接收表示第一发送方的声音和第二发送方的声音的信号(210)。 该方法还包括分别获得(212)对第一和第二发送方的声音活动的度量,并且基于获得的声音活动度量选择(214)第一角度和/或第二角度。 该方法还包括将接收到的信号处理(216)为经处理的信号,使得来自第一发送方的声音由接收方经历,从第一角度发出,而来自第二发送方的声音被从第二角度发出 对于接收方。 最后输出表示经处理的信号的信号(218)。

    • Conference bridge (1) for managing an audio scene comprising two or more participants, the conference bridge comprising a mixer (2) and several user channels (3a, 3b, 3N). The conference bridge is arranged to continuously create a 3D positional audio environment signal for each participant as a listening participant, by rendering the speech of each participant as a 3D positioned virtual sound source and excluding the speech of the listening participant, and to distribute each created 3D positional audio environment signal to the corresponding listening participant. Further, the conference bridge is arranged to place the virtual sound source corresponding to each participant at the same spatial position relative the listening participant in every created 3D positional audio environment.
    • 会议桥(1),用于管理包括两个或多个参与者的音频场景,所述会议桥包括混合器(2)和多个用户通道(3a,3b,3N)。 会议桥被布置为通过将每个参与者的语音渲染为3D定位的虚拟声源并排除听众参与者的语音,并且分发每个创建的会话桥,每个参与者作为聆听参与者持续创建3D位置音频环境信号 3D位置音频环境信号到相应的听力参与者。 此外,会议桥被布置成在每个创建的3D位置音频环境中将与每个参与者对应的虚拟声源相对于聆听参与者放置在相同的空间位置。
