Efficient detection of co-located participant devices in teleconferencing sessions

A participant computing device connected to a teleconferencing session, comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media that store instructions that, when executed by the one or more processors, cause the participant computing device to perform operations, the operations comprising:
• obtaining audio data captured using an audio capture device associated with the participant computing device, wherein the audio data comprises audio originating from an audio source co-located with the participant computing device;
• subsequent to obtaining the audio data, receiving second audio data that travelled farther to reach the participant computing device than the audio data and that comprises second audio captured using a plurality of second audio capture devices respectively associated with a plurality of second participant computing devices that are connected to the teleconferencing session;
• based on the reception of the second audio data subsequent to the capture of the audio data, making a determination that at least a portion of the second audio originates from the audio source co-located with the participant computing device;
• and
• based on the determination, generating co-location information indicating that the participant computing device is co-located with at least one of the plurality of second participant computing devices.

One or more non-transitory computer-readable media that store instructions that, when executed by one or more processors of a participant computing device connected to a teleconferencing session, cause the one or more processors to perform operations, the operations comprising:

• subsequent to obtaining the audio data, receiving second audio data that comprises second audio captured using a plurality of second audio capture devices respectively associated with a plurality of second participant computing devices that are connected to the teleconferencing session;
• subsequent to obtaining the audio data, separately receiving second audio data that travelled farther to reach the participant computing device than the audio data, the second audio data comprising audio captured by a second participant computing device and third audio data comprising audio captured by a third participant computing device, wherein the second audio data indicates the second participant computing device as an originating source of the second audio data;
• based on the reception of the second audio data subsequent to the capture of the audio data, making a determination that at least a portion of the second audio originates from the audio source co-located with the participant computing device;
• and
• based on the determination, generating co-location information indicating that the participant computing device is co-located with the second participant computing device.
