Content-Based Audio Comparisons

A system comprising:

• a computer-readable medium tangibly storing at least a first audio signal and a second audio signal;
• and
• a computing system including processor electronics configured to perform operations comprising:
• comparing a first set of spectral characteristics associated with a portion of the first audio signal with a second set of spectral characteristics associated with a portion of the second audio signal to identify a degree of difference, wherein the portion of the first audio signal is equivalent in duration to the portion of the second audio signal;
• detecting that the first set of spectral characteristics corresponds to the second set of spectral characteristics when the identified degree of difference is within a degree of accuracy;
• and
• determining, in response to the detecting, that the second audio signal includes the portion of the first audio signal.

A computer-readable storage medium, tangibly embodying a computer program product configured to cause data processing apparatus to perform operations comprising:

• generating a first set of spectral characteristics associated with a portion of a first audio signal;
• comparing the first set of spectral characteristics with a second set of spectral characteristics associated with a portion of a second audio signal to identify a degree of difference, wherein the portion of the first audio signal is equivalent in duration to the portion of the second audio signal;
• detecting that the first set of spectral characteristics corresponds to the second set of spectral characteristics when the identified degree of difference is within a degree of accuracy;
• and
• determining, in response to the detecting, that the second audio signal includes the portion of the first audio signal.

A computer-implemented method of comparing audio signals, the method comprising:

• generating, using a processor, sets of spectral characteristics associated with a first audio signal and sets of spectral characteristics associated with a second audio signal;
• comparing, using a processor, the sets of spectral characteristics associated with the first audio signal with corresponding sets of spectral characteristics associated with the second audio signal to identify a degree of difference, wherein corresponding sets of spectral characteristics are individually compared;
• and
• determining that the second audio signal includes the first audio signal when the identified degree of difference compares in a predetermined manner to a specified degree of accuracy.
