Abstract
Some embodiments of the invention are directed to techniques for suppressing or attenuating noise in audio circuitry, such as which may result from a source of electromagnetic energy being coupled to the audio circuitry. Some embodiments may employ two separate channels, a first of which captures audio information and noise, and a second of which captures the noise. Noise compensation may be performed by transforming the signal of the first channel in accordance with noise in the second channel which is identified as comprising a particular type of noise.
