METHODS AND APPARATUS TO DYNAMICALLY GENERATE AUDIO SIGNATURES ADAPTIVE TO CIRCUMSTANCES ASSOCIATED WITH MEDIA BEING MONITORED

摘要

Methods and apparatus to dynamically generate audio signatures adaptive to circumstances associated with media being monitored are disclosed. An example apparatus includes a signal selector to select a first signature scheme from among a plurality of signature schemes to generate monitored signatures for media being monitored by a meter. The first signature scheme is selected based on a circumstance associated with the media. The apparatus includes a signal generator to generate a first monitored signature from the media based on the first signature scheme. The apparatus further includes a communications interface to transmit the first monitored signature to a data collection facility.
