Claim:
1. A method of matching a digitized stream of audio signals in a stream audio print to a known audio print, 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 signal analysis was performed on the sound and silence within the audio stream to compute the stream audio print, wherein the stream audio print was computed by identifying a pattern associated with the audio stream, wherein the pattern is comprised of at least two of sound, silence and frequency, and wherein the pattern matches a similar pattern of at least two of sound, silence and frequency in a known audio print from a library of known audio prints; 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; and determining, at the processor, a potential match between the stream audio print and the known audio print.
