Abstract
Example apparatus disclosed herein are to receive a log file, compare a first media monitor identification associated with an audio signature, a second media monitor identification associated with media metadata, and a third media monitor identification associated with event metadata. Disclosed example apparatus are also to determine if a first timestamp associated with the audio signature is within a time period, wherein the time period begins with a second timestamp associated with the media metadata and ends with a third timestamp associated with the event metadata. Disclosed example apparatus are also to validate that the audio signature satisfies a threshold for being stored as a reference signature based on at least one of the media metadata, the event metadata, the first timestamp, the second timestamp, or the third timestamp. Disclosed example apparatus are also to generate the reference signature including assigning the media metadata to the audio signature.
