Abstract:
An audio signal controlling method includes identifying whether an audio zooming effect is used for at least one audio object present in a virtual reality (VR) through an audio zooming effect field included in metadata, and controlling an audio signal corresponding to the audio object based on a preset method when the audio zooming effect is identified as being used.
