Title:
ACOUSTIC SIGNAL PROCESSING METHOD, COMPUTER PROGRAM, AND ACOUSTIC SIGNAL PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/084950
Kind Code:
A1
Abstract:
An acoustic signal processing method comprising: an acquisition step for acquiring sound data indicating the waveform of a reference sound; a processing step for processing the sound data so as to change at least one of a frequency component, the phase, and the amplitude value of the waveform on the basis of mimicry information that mimics fluctuations in a natural phenomenon; and an output step for outputting the processed sound data.
