1. A computer-implemented method, executed on a computing device, comprising:
receiving a signal from each microphone of a plurality of microphones, thus defining a plurality of signals;
determining a total harmonic distortion associated with at least one microphone; and
performing one or more harmonic distortion-based augmentations on the plurality of signals based upon, at least in part, the total harmonic distortion associated with the at least one microphone, thus defining one or more harmonic distortion-based augmented signals.
