A first computing device captures audio data via an audio capture device. The audio data comprises probe signals from second computing devices located within the same area. The first computing device and the second computing devices are connected to a teleconference session. Based on the audio data, the first computing device generates a first encoding of the probe signals received. The first computing device receives a second encoding of probe signals received at a second computing device. The first computing device makes a determination that a degree of similarity between the first encoding and the second encoding is greater than or equal to a threshold degree of similarity. The first computing device generates co-location information identifying the second computing device as a co-located device that is located within the same area as the first computing device.

Local signaling of encoded audio for detection of co-located devices

Delay reporting information descriptive of an existing delay of the participant computing device is received from each participant computing device of a participant cohort. The existing delay includes a period of time between transmission of audio data from the teleconference computing system and receipt of the audio data by the participant computing device. The participant cohort includes multiple participant computing devices that are co-located within a same area and are connected to a teleconference hosted by the teleconference computing system. A target delay is determined for the participant cohort. The target delay includes a period of time greater than the existing delay of participant computing devices. The target delay is configured to cause synchronized audio playback when implemented by the devices. Target delay information indicative of the target delay is provided to the participant cohort.
