Abstract: The technology disclosed relates to audio signal processing. It includes a series of modules that individually are useful to solve audio signal processing problems. Among the problems addressed are buzz removal, selecting a pitch candidate among pitch candidates based on local continuity of pitch and regional octave consistency, making small adjustments in pitch, ensuring that a selected pitch is consistent with harmonic peaks, determining whether a given frame or region of frames includes harmonic, voiced signal, extracting harmonics from voice signals and detecting vibrato. One environment in which these modules are useful is transcribing singing or humming into a symbolic melody. Another environment that would usefully employ some of these modules is speech processing. Some of the modules, such as buzz removal, are useful in many other environments as well.

Abstract: A first embodiment of the invention provides a method and apparatus for attenuating or amplifying voice or other signals present on a stereo audio recording that uses frequency domain techniques to calculate a time- and frequency-dependent gain factor, based on the input panning and phase information in the recording, and optionally outputs the original recording's phase and/or panning information. A further embodiment of the invention provides a method and apparatus for attenuating or amplifying voice or other signals present on a stereo audio recording that uses training-based frequency domain techniques in each frequency band to calculate a time- and frequency-dependent gain factor, based on the input panning, phase offset, and magnitude information in the recording, and optionally outputs the original recording's phase and/or panning information
