Audio data processing device and control method for an audio data processing device

Abstract

An audio data processing device according to an aspect of the present disclosure includes: a sound field effect data generator configured to add sound field effect data to audio data by arithmetic operation processing using a parameter, at least one processor, and at least one memory device that stores a plurality of instructions, which when executed by the at least one processor, causes the at least one processor to operate to: analyze a scene for the audio data, recognize switching of the scene based on an analysis result of the scene, gradually decrease both an input gain and an output gain of the sound field effect data generator, and gradually increase both the input gain and the output gain after changing the parameter.

Dependencies are inferred from the claim text.
