Dynamic distortion elimination for output audio

An audio processing system, comprising:

• an input audio transducer that detects an output acoustic signal;
• an analog-to-digital converter that generates a receive audio signal based, at least in part, on the detected output acoustic signal;
• a comparator that compares a frequency domain representation of the receive audio signal to a frequency domain representation of a source audio signal from which the output acoustic signal is generated;
• a harmonic analyzer that identifies at least one distortion signal in the receive audio signal;
• and
• a dynamic equalizer that selectively equalizes the source audio signal to reduce an amplitude of the source audio signal at a frequency that correlates to the distortion signal.

A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for improving quality of output audio, said method steps comprising:

• detecting an output acoustic signal via an input audio transducer;
• generating a receive audio signal based, at least in part, on the detected output acoustic signal;
• comparing a frequency domain representation of the receive audio signal to a frequency domain representation of a source audio signal from which the output acoustic signal is generated;
• identifying at least one distortion signal in the receive audio signal;
• and
• selectively equalizing the source audio signal to reduce an amplitude of the source audio signal at a frequency that correlates to the distortion signal.

A mobile station, comprising:

• a harmonic analyzer that identifies at least one distortion signal in the receive audio signal;
• and
• a dynamic equalizer that selectively equalizes the source audio signal to reduce an amplitude of the source audio signal at a frequency that correlates to the distortion signal.
