    Abstract: An end user can sample a radio or television broadcast, generate a user representation of the broadcast sample, and send the user representation to a comparison system, which also receives known representations of content broadcast by multiple different stations. The known representations are stored in a continuous fashion, and represent actually broadcast content. The comparison system identifies the source of the broadcast sample by comparing the user representation to the known representations associated with each of the different stations. By comparing two representations of content that was actually broadcast, a broadcast source can be identified without requiring the use of watermarks, timestamps, or a database of discreet content items.

    Abstract: Methods and apparatus to monitor media exposure are disclosed. An example implementation includes accessing a meter identifier and first audio received from a wearable bracelet meter, the meter identifier uniquely associated with the wearable bracelet meter. Whether the first audio substantially matches second audio received at a second meter is determined. In response to determining that the first audio and the second audio substantially match, the meter identifier associated with the wearable bracelet meter and at least one of the first audio or the second audio are stored.

    Abstract: Methods and apparatus to identify media content using temporal signal characteristics are disclosed. An example method to identify media content includes generating a first signature based on a media content signal, the first signature comprising a plurality of first normalized features, each normalized feature corresponding to a signal peak and located at a temporal location of the signal peak in the audio signal, correlating the first signature to a reference signature comprising second normalized features to obtain an index, and determining that the first signature represents the same media content as the reference signature when the index is greater than a threshold.
