Appl. No.:

15/851503

Inventors:

- Arlington VA, US

International Classification:

H04S 7/00

Abstract:

An exemplary ambient sound extraction system accesses a location-confined A-format signal that includes a first set of audio signals captured by different capsules of a multi-capsule microphone disposed at a first location with respect to a capture zone of a real-world scene. The ambient sound extraction system also accesses a second set of audio signals captured by a plurality of microphones disposed at a plurality of other locations with respect to the capture zone. The ambient sound extraction system generates a location-diffused A-format signal. The location-diffused A-format signal includes a third set of audio signals that is based on the first and second sets of audio signals. Based on the location-diffused A-format signal, the ambient sound extraction system generates a location-diffused B-format signal representative of ambient sound in the capture zone. Corresponding methods are also disclosed.

Abstract:

A virtual provider edge server may include different modules that implement a hybrid provider edge. A flow detection module may sample received traffic through a server and adaptively detect flows to be offloaded. An offloading module may be an SDN controller that controls the flow tables of a switch that data traffic is offloaded to.
