Abstract

System, methods, and media that: receive a first piece of audio content; identify a first plurality of atoms that describe at least a portion of the first piece of audio content using a Matching Pursuit algorithm; form a first group of atoms from at least a portion of the first plurality of atoms, the first group of atoms having first group parameters; form at least one first hash value for the first group of atoms based on the first group parameters; compare the at least one first hash value with at least one second hash value, wherein the at least one second hash value is based on second group parameters of a second group of atoms associated with a second piece of audio content; and identify a match between the first piece of audio content and the second piece of audio content based on the comparing.
