Abstract: A dynamics processing method including receiving an input audio signal determining whether a level of the input audio signal exceeds a threshold value, determining whether a first amount of time, that is not specified to a unique value by a first speed at which a gain applied to the input audio signal is changed, has elapsed from when the level of the input audio signal exceeded the threshold value, and changing the gain applied to the input audio signal at the first speed.

Abstract: A method for setting a filter frequency response includes: dividing a target frequency band into multiple first partial bands at a frequency corresponding to an intersection between a first line representative of a target spectrum envelope and a second line representative of a first spectrum envelope derived from smoothing a measured frequency spectrum; and setting a frequency response of a filter corresponding to a first partial band specified by an operator from among the multiple first partial bands, in accordance with a setting operation for setting an adjustment amount performed by the operator with respect to the specified first partial band.
