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.

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

A sound effect producing apparatus includes an input portion, a memory portion, a pseudo sound reflection producing portion, and an effect provision portion. The input portion performs inputting of an audio signal. The memory portion stores sound effect information that includes production information for producing a pseudo sound reflection corresponding to a sound reflection generated in a predetermined acoustic space and sound source position information showing a sound source position of the pseudo sound reflection. The pseudo sound reflection producing portion produces a pseudo sound reflection based on the production information. The effect provision portion performs a process of localizing the pseudo sound reflection using a predetermined direction as a reference, based on the audio signal and the sound source position information.

Sound effect producing apparatus, method of producing sound effect and program therefor

An audio processor acquires processed sound data, which is obtained by processing original sound data according to a content of processing defined such that first sound is emitted under the standard sound emission condition, in association with a sound emission device, acquires a control signal, and acquires a device sound emission condition. In order to make second sound emitted by the sound emission device under the acquired device sound emission condition close to the first sound, the audio processor identifies the correction content of the processed sound data based on a difference between the device sound emission condition and the standard sound emission condition, the control signal, and the processed sound data acquired in association with the sound emission device. The audio processor corrects the processed sound data according to the correction content, and supplies the corrected processed sound data to the sound emission device.

Information processor, audio processor, audio processing system and program

An information processor includes a generator that is adapted to generate original sound data indicating an original sound as a basis for a processed sound to be heard by a user and a parameter indicating a content of processing on the original sound data, an original sound data output section that is adapted to output the original sound data generated by the generator from any channel of a plurality of channels, and a control signal output section that is adapted to output a control signal including the parameter and a correspondence relationship between the parameter and the channel for the original sound data to be processed by means of the parameter.
