Abstract:
1. A method of matching a digitized stream of audio signals to a known audio recording, the method comprising: receiving, at a processor, an audio stream from an application; performing, at the processor, signal analysis on the audio stream to compute a stream audio print of the audio stream, wherein the audio stream is comprised of sound and silence, wherein the stream audio print is computed on sound and silence, wherein the stream audio print identifies a pattern associated with the audio stream, wherein the pattern is comprised of at least two of sound, silence and frequency, wherein the pattern matches a similar pattern of at least two of sound, silence and frequency in known audio print from a library of known audio prints, and wherein the signal analysis is performed on sound and silence within the audio stream; applying, at the processor a silence constraint to match periods of silence in the stream audio print to periods of silence in the known audio print from the library of known audio prints, wherein the silence constraint is associated with the known audio print; if application of the silence constraint is successful, computing, at the processor, a total scoring metric function associated with a potential match to identify a match between the stream audio print and the known audio print, wherein computing the total scoring metric function comprises: determining, at the processor, the potential match between the stream audio print and the known audio print.
