This disclosure describes an apparatus and method of an embodiment of an invention that is a band-limited beamforming microphone array with acoustic echo cancellation that includes: a plurality of first microphones configured as a beamforming microphone array to resolve first audio input signals within a first frequency range, the beamforming microphone array includes acoustic echo cancellation; one or more additional microphone(s) configured to resolve second audio input signals within a restricted second frequency range such that the additional microphone(s) are coupled to the beamforming microphone array; augmented beamforming that processes audio signals from the beamforming microphone array and the additional microphone(s).

Band-limited beamforming microphone array with acoustic echo cancellation

This disclosure describes a band-limited beamforming microphone array made by the augmenting a beamforming microphone array with non-beamforming microphones. The band-limited beamforming microphone array includes a plurality of first microphones configured as a beamforming microphone array to resolve first audio input signals within a first frequency range. The band-limited array further includes one or more additional microphone configured to resolve second audio input signals within a restricted second frequency range such that the additional microphones are coupled to the beamforming microphone array. In addition, the band-limited array includes augmented beamforming that processes audio signals from the beamforming microphone array and the additional microphone(s), where the augmented beamforming combines the beamformed first audio input signal with the resolved and restricted second audio input signals to create an audio signal within a band-limited frequency range.

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.

Conferencing system with spatial rendering of audio data

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.

VOIP device, VOIP conferencing system, and related method

Embodiments of the present disclosure include an apparatus () configured to perform beamforming on multiple audio input signals. The apparatus () includes a first plurality of microphones () configured to resolve first audio input signals within a first frequency range. The apparatus () also includes at least one microphone () configured to resolve second audio input signals within a second frequency range. A lowest frequency in the first frequency range is greater than a lowest frequency in the second frequency range.
