Claim 0:
1. A method comprising, at an electronic device having an array of microphones and a processor:
receiving a plurality of microphone signals from the array of microphones;
generating a processed audio signal from the plurality of microphone signals;
compensating for coloration in the processed audio signal in accordance with a plurality of compensation coefficients by frequency response equalizing the processed audio signal, comprising:
generating first spectrum values from the processed audio signal;
generating multiple second spectrum values from each of at least two but less than a full value of the plurality of microphone signals;
generating reference spectrum values from the multiple second spectrum values; and
generating the plurality of compensation coefficients from the reference spectrum values and the first spectrum values,
wherein the the compensating reduces a predefined difference measure between a predefined norm of spectrum values of the compensated processed audio signal and the reference spectrum values.
