1. A method comprising:

  • receiving a signal;

    estimating a frequency response by performing a spectral analysis of the signal;

    computing average amplitudes over a user-selectable subset of time samples for each frequency estimated by the spectral analysis;

    comparing the averaged amplitudes to a stored set of averaged amplitudes, to yield equalization coefficients;

    applying the equalization coefficients to the frequency response, to yield an equalized frequency response; and

    comparing the equalized frequency response to a stored frequency response using a classifier.
