Abstract
A system includes a plurality of channels, a parameter calculator, and an equalizer. Each channel receives a plurality of input signals that represent an input to a speaker. Each channel generates real and imaginary components of a transfer function of the speaker based on the plurality of input signals. The parameter calculator calculates a plurality of parameters of the speaker based on the real and imaginary components of the transfer function received from each channel. The equalizer adjusts the input to the speaker based on the parameters.
