1. A method, comprising: receiving, by a processor coupled to a plurality of sensors, at least a first input signal and a second input signal in a time domain from the plurality of sensors; converting, by the processor, the first and second input signals from the time domain to a frequency domain input signal; estimating, by the processor, a magnitude response difference between the first and second input signals based, at least in part, on the frequency domain input signal; converting, by the processor, the magnitude response difference into a time domain impulse response; constraining, by the processor, the time domain impulse response to have a linear phase response; and filtering, by the processor, at least one of the first input signal and the second input signal based, at least in part, on the constrained time domain impulse response.
