Systems, Methods, and Media for Identifying Matching Audio

A method for identifying matching audio comprising:

• receiving a first piece of audio content;
• identifying a first plurality of atoms that describe at least a portion of the first piece of audio content using a Matching Pursuit algorithm;
• forming 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;
• forming at least one first hash value for the first group of atoms based on the first group parameters;
• comparing 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
• identifying a match between the first piece of audio content and the second piece of audio content based on the comparing.

A computer-readable medium containing computer-executable instructions that, when executed by a processor, cause the processor to perform a method for identifying matching audio, the method comprising:

• receiving a first piece of audio content;
• identifying a first plurality of atoms that describe at least a portion of the first piece of audio content using a Matching Pursuit algorithm;
• forming 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;
• forming at least one first hash value for the first group of atoms based on the first group parameters;
• comparing 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
• identifying a match between the first piece of audio content and the second piece of audio content based on the comparing.
