Abstract
A method of processing an audio signal includes inputting an audio signal, obtaining position information of a sound source of the audio signal, receiving an input of movement information, moving a position of the sound source around a predetermined axis, based on the movement information, changing a sound image localization position of the sound source, and performing localization processing on the audio signal so as to localize a sound image of the sound source at a changed sound image localization position.
Claims20
A method of processing an audio signal, the method comprising:
- inputting an audio signal;
- obtaining position information of a sound source of the audio signal;
- receiving of the input of movement information;
- moving a position of the sound source around a predetermined axis, based on the movement information;
- changing a sound image localization position of the sound source;
- and
- performing localization processing on the audio signal so as to localize a sound image of the sound source at a changed sound image localization position.
An audio signal processing apparatus comprising:
- an audio signal inputter that inputs an audio signal;
- a position information obtainer that obtains position information of a sound source of the audio signal;
- a movement information receiver that receives an input of movement information;
- a sound source position controller that moves a position of the sound source around a predetermined axis, based on the movement information, and changes a sound image localization position of the sound source;
- and
- a localization processor that performs localization processing on the audio signal so as to localize a sound image of the sound source at the sound image localization position that has been changed by the sound source position controller.
