Abstract

This disclosure describes a conferencing system with spatial rendering of audio data. The conferencing system includes a local conferencing device that includes a plurality of microphones, an audio encoder, and a spatial encoder that are associated with a local endpoint. The conferencing system further includes a remote conferencing device that includes a plurality of speakers, an audio decoder, and a spatial renderer that are associated with the remote endpoint. 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.
