Abstract:
An example system includes a filter bank of sub-octave filters to separate a lower frequency portion of an audio input stream into a number of sub-bands. A detector bank of detectors coupled with the filter bank determines an audio power level in each of the sub-bands. A sub-band selection engine coupled with the detector bank determines a dominant sub-band. A first filter engine isolates the dominant sub-band from the audio input stream and a harmonic engine coupled with the first filter generates harmonics of the dominant sub-band. A second filter engine coupled with the harmonic engine selects a sub-set of the harmonics to combine with a higher frequency portion of the audio input stream.

Claim (Index 16):
The system of  claim 1 , wherein the filters of the filter bank have overlapping cutoff frequencies.
