A client computing device is configured to capture an audio signal, the audio signature being indicative of acoustics of surroundings of the client computing device. A signature is generated based upon a high frequency portion of the captured audio signal, and the signature is compared with other signatures. The other signatures are generated based upon high frequency portions of audio signals captured by other computing devices. A determination regarding the client computing device being co-located with a second client computing device is made based upon the comparison of the signature with the other signatures."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Proximity discovery using audio signals","description":"Various technologies pertaining to computing data that is indicative of a location of a client computing device are described herein.
