Claim:
1. A method of identifying proximate devices, the method comprising the steps of: recording, in each device, an audio signal so as to produce respective audio samples, detecting, in each device, a detected sensory identifier, and transmitting the respective audio samples from one or more of the devices to a server or another of the devices, wherein the server or device receiving the respective audio samples comprises a processor, a memory and software configured to perform the remaining steps of using said detected sensory identifier for matching the devices, using said detecting as a trigger to select a common time interval of audio samples at a predetermined relative temporal position offset with respect to a time point of the detected sensory identifier; comparing respective audio samples recorded during the common time interval by different ones of the devices with each other, and deciding that the devices are proximate only if the respective audio samples are sufficiently similar.
