Abstract
Methods, apparatus, systems and articles of manufacture are disclosed to reduce noise from harmonic noise sources. Example methods disclosed herein include determining a point of comparatively large amplitude for a frequency in an audio sample, generating a contour trace beginning at the point, and calculating a parameter for the contour trace. The example method includes, in response to the contour trace being an outlier based on the parameter, removing the contour trace from the audio sample.
