Abstract
Systems and methods for signal noise reduction. An input digital signal may be partitioned into a series of adjacent segments. The adjacent segments may be converted to a frequency domain representation. A particular spectral component of a particular segment may be compared to a related spectral component of a first segment adjacent the particular segment, and to a related spectral component of a second segment adjacent the particular segment. The particular spectral component may be modified upon a magnitude value of the particular spectral component satisfying at least one of a predetermined set of conditions.
