Patent ID: 8244535

Claim:
A method, comprising: receiving a plot profile including at least one of an identified range of audio frequencies; receiving an audio signal; and processing the audio signal into a remapped audio signal using the plot profile, the processing comprising: retrieving an identified range of audio frequencies from the plot profile; determining a range of impaired audio frequencies in the audio signal based on the identified range of audio frequencies; determining a minimum frequency, a maximum frequency, and a center frequency of the impaired frequency range; shifting the frequency of at least a subset of a lower portion of the impaired audio frequencies from the minimum frequency up to the center frequency downward to outside of the identified range; shifting the frequency of at least a subset of a higher portion of the impaired audio frequencies from the center frequency up to the maximum frequency upward to outside of the identified range; and continuing to retrieve identified ranges of audio frequencies from the plot profile, and shifting the impaired audio frequencies of the audio signal, until no further identified ranges of audio frequencies are available for consideration.
