This abstract first appeared for US patent application 20240422478 titled 'COMPUTER-IMPLEMENTED BASS ENHANCEMENT METHOD AND BASS ENHANCEMENT APPARATUS
Original Abstract Submitted
a computer-implemented bass enhancement method includes: extracting, from an input audio signal including harmonic sound components and inharmonic sound components, an inharmonic sound signal representing the inharmonic sound components which are other than the harmonic sound components; generating, from the inharmonic sound signal, a low frequency signal with a frequency that is one n-th a frequency of a fundamental wave component of the inharmonic sound signal, where n is an integer greater than one; and generating, from the low frequency signal and the input audio signal, a bass-range enhancement signal that enhances bass-range frequencies of the input audio signal.
