    Abstract: Some implementations involve analyzing audio packets received during a time interval that corresponds with a conversation analysis segment to determine network jitter dynamics data and conversational interactivity data. The network jitter dynamics data may provide an indication of jitter in a network that relays the audio data packets. The conversational interactivity data may provide an indication of interactivity between participants of a conversation represented by the audio data. A jitter buffer size may be controlled according to the network jitter dynamics data and the conversational interactivity data. The time interval may include a plurality of talkspurts.

    Abstract: An audio apparatus is configured to switch, when there exists a first audio interface between the audio apparatus and a computer apparatus, to using a second audio interface between the audio apparatus and the computer apparatus, the second audio interface being different from the first audio interface. The switching comprises: receiving, via the first audio interface, combined audio data and non-audio data, the non-audio data comprising a request to switch to using the second audio interface; obtaining the request from the data; and, in response to obtaining the request, transmitting to the computer apparatus a confirmation of switching to using the second audio interface. The audio apparatus and the computer apparatus are described and claimed.

    Abstract: An audio spatial rendering apparatus and method are disclosed. In one embodiment, The audio spatial rendering apparatus includes a rendering unit for spatially rendering an audio stream so that the reproduced far-end sound is perceived by a listener as originating from at least one virtual spatial position, a real position obtaining unit for obtaining a real spatial position of a real sound source, a comparator for comparing the real spatial position with the at least one virtual spatial position; and an adjusting unit for, where the real spatial position is within a predetermined range around at least one virtual spatial position, or vice versa, adjusting the parameters of the rendering unit so that the at least one virtual spatial position is changed.

    Abstract: The present document relates to setting up and managing two-dimensional or three-dimensional scenes for audio conferences. A conference controller (111, 175) configured to place an upstream audio signal (123, 173) associated with a conference participant within a 2D or 3D conference scene to be rendered to a listener (211) is described. An X-point conference scene with X different spatial talker locations (212) is set up within the conference scene, wherein the X talker locations (212) are positioned within a cone around a midline (215) in front of a head of the listener (211). A generatrix (216) of the cone and the midline (215) form an angle which is smaller than or equal to a pre-determined maximum cone angle. The upstream audio signal (123, 173) is assigned to one of the talker locations (212) and metadata identifying the assigned talker location (212) are generated, thus enabling a spatialized audio signal.
