Abstract: In one embodiment, a network interface broadcasts an audible message from a first computing device to a plurality of second computing devices over a first channel. The audible message comprises an audible noise broadcasted using a plurality of frequencies and a first unique identifier indicative of the first computing device. The network interface receives an acknowledgment message from each of the plurality of second computing devices over a second channel. A processor identifies each of the plurality of second computing devices based on the second unique identifier in the acknowledgment message and initiates a collaboration session between the first computing device and the plurality of second computing devices by sending a collaboration message from the first computing device to the plurality of second computing devices. The collaboration message automatically causes the plurality of second computing devices to enter the collaboration session.

Abstract: The present technology can receive audio segments from sources within one or more conference room, and can create audio fingerprints from the sources. The audio fingerprints are optimized for audio in conference room environments, which include distortions from room impulse responses, and various encoding used by telecommunication networks. In some embodiments, when two audio segments are matched, a user equipment can be instructed to mute its speakers to avoid feedback. In some embodiments, when two audio segments are matched, a user equipment can be given instructions to join a conference taking place in the room in when the audio segment originated.
