Abstract: A system for monitoring media exposure is provided. The system includes a remote device configured to receive a sample audio signal, to extract at least one unique parameter of the sample audio signal and to form a first dataset including data related to a presence of the unique parameter; a central device configured to receive the first dataset from the remote device, and to obtain at least one second dataset related to a presence of at least one unique parameter extracted from a media audio signal received from at least one media source; wherein the central device is further configured to evaluate correspondence between the first dataset and the second dataset and to collect data related to exposure of the remote device to the at least one media audio signal in accordance with the correspondence.
