SOUND PROCESSING DEVICE, SOUND PROCESSING METHOD, AND SOUND PROCESSING PROGRAM

摘要

A sound processing device includes a storage unit configured to store first operation data corresponding to a motion of a mechanical apparatus and a first sound feature value corresponding to the motion in correlation with each other, a noise estimating unit configured to estimate a third sound feature value corresponding to a noise component based on a second sound feature value corresponding to an acquired sound signal, a sound feature value processing unit configured to calculate a target sound feature value from which the noise component is removed based on the second sound feature value and the third sound feature value, and an updating unit that updates the first sound feature value stored in the storage unit based on detected second operation data and the third sound feature value estimated by the noise estimating unit.
