A method of identifying at least two proximate devices (1, 2) comprises the steps of: recording, in each device, an audio signal (AS) so as to produce respective audio samples, detecting, in each device, a sensory identifier serving as a trigger (TR), comparing the audio samples during a common interval (I) defined relative to the trigger (TR), and deciding that the event is common to the devices only if the respective audio samples are sufficiently similar. The common interval (I) starts prior to the trigger (TR) and preferably also ends prior to the trigger.
