Abstract
An apparatus instantiating a method for computing automatic noise compensation gain with an adaptive filter that receives ambient sound and source audio, down samples ambient sound and source audio, and filters the down sampled ambient sound and source audio to compute an RMS noise estimate from which a gain is determined. The present invention features highly efficient computations, as sampling rates are significantly lower. The present invention keeps audio data secure by transmitting only the mean-square audio levels instead of the audio itself.
