1. A system comprising:
at least one processor;
a non-transitory computer-readable medium having stored therein instructions that, upon execution by the at least one processor, cause the system to perform operations comprising:
receiving monitoring data corresponding to a media presentation presented via a browser of a computing device, the received data including a first sequence of audio signatures associated with first timestamps, a second sequence of entries of media metadata associated with second timestamps;
comparing a first set of media identifications associated with respective ones of the first sequence of audio signatures, and a second set of media identifications associated with respective ones of the second sequence of entries of the media metadata;
determining, based on the comparing, that the first sequence of audio signatures and the second sequence of entries of media metadata are associated with a same media identification;
validating at least one of the audio signatures, wherein the validating includes determining that each of one or more of the first timestamps are between two successive ones of the second timestamps, wherein the two successive ones of the second timestamps are each associated with respective entries of media metadata associated with the same media identification, and wherein the validated at least one of the audio signatures includes the audio signatures associated with the determined one or more of the first timestamps; and
in response to validating the at least one of the audio signatures, generating at least one reference signature based on the validated at least one signature, wherein the at least one reference signature is associated with one or more of the entries of media metadata associated with two successive ones of the second timestamps which the determined one or more of the first timestamps are between.
