Abstract:
1. A method for identifying recorded sound signals comprising: receiving a sound stream including an unidentified recorded sound; processing the received sound stream to determine an index set of values corresponding to characteristics of the unidentified recorded sound, wherein the index set of values comprises fingerprint and landmark pairs, wherein the landmark indicates a distinctive and reproducible location for determining the fingerprint for the unidentified recorded sound; searching a library using fingerprints of the fingerprint and landmark pairs, the library having sets of values corresponding to characteristics of a plurality of library recorded sounds, wherein each of the sets of values in the library comprises fingerprint and landmark pairs, wherein the landmark indicates a distinctive and reproducible location for determining the fingerprint for each of the library recorded sounds; identifying, via a processor, one or more landmarks in the library corresponding to fingerprints in the library that match any of the fingerprints of the index set of values; and determining a library recorded sound matching the unidentified recorded sound based on an amount of the one or more landmarks in the library recorded sound having a matching time difference between landmarks of matching fingerprints of the index set of values.
