Abstract:
1. A method for identifying a broadcast source of content comprising: receiving an audio sample and a time at which the audio sample was recorded, the audio sample being a rendition of a segment of an original recording; identifying characteristics of the audio sample and an estimated time offset of the audio sample, the estimated time offset of the audio sample defining a time difference between a beginning of the original recording and a beginning of the audio sample; comparing the characteristics and the estimated time offset of the audio sample with characteristics and time offsets of broadcast samples taken from broadcast stations at approximately the time at which the audio sample was recorded, each of the time offsets of the broadcast samples defining a time difference between a beginning of a broadcast sample and a beginning of a corresponding original recording; and based on the comparison, identifying a broadcast station from which the audio sample was broadcast.
