VOIP device, VOIP conferencing system, and related method

摘要

Voice over internet protocol (VoIP) devices and conferencing systems may include a spatial encoder associated with a first endpoint and a spatial renderer associated with a second endpoint. The spatial renderer may configured to receive audio data. The audio data may be rendered among a plurality of speakers based on a first set of spatial information for a plurality of microphones associated with the first endpoint, and a second set of spatial information for the plurality of speakers associated with the second endpoint. A method for generating a sound field may include determining spatial information for a plurality of microphones in a local room, determining spatial information for a plurality of speakers in a remote room, mapping the spatial information for the plurality of microphones and the spatial information for the plurality of speakers, and generating a sound field in the remote room based on the mapping.

主权项

1. A voice over internet protocol (VoIP) device, comprising: a second VoIP engine having a spatial renderer associated with a second endpoint, the spatial renderer configured to:
receive a first set of spatial information for a plurality of microphones associated with a first endpoint during a call set up procedure; send a second set of spatial information for a plurality of speakers associated with the second endpoint to a first VoIP engine associated with the first endpoint during a call set up procedure; receive audio data from the first endpoint, and render the audio data among the plurality of speakers based, at least in part, on the first set of spatial information and the second set of spatial information; wherein the spatial renderer is configured to superimpose a coordinate system for the plurality of speakers and a coordinate system for the plurality of microphones during spatial rendering of the audio data.
