METHODS AND APPARATUS TO ENHANCE AN AUDIO SIGNAL

Abstract:

Methods, apparatus, systems, and articles of manufacture are disclosed to enhance and audio signal. An example apparatus includes processor circuitry to at least determine a first signal spectrum corresponding to a first microphone, the first signal spectrum identifying first audio, determine a second signal spectrum corresponding to a second microphone, the second signal spectrum identifying the first audio, the second spectrum different from the first spectrum, the first microphone different from the second microphone, the second signal spectrum having a first spectral distance to the first signal spectrum, calculate a mask based on the first and second signal spectrums, and generate a third signal spectrum corresponding to the first microphone utilizing the mask and the first signal spectrum, the third signal spectrum different from the first signal spectrum, the third signal spectrum having a second spectral distance to the second signal spectrum, the second spectral distance less than the first spectral distance.
