Abstract
An audio signal processing apparatus and an audio signal processing method are disclosed. The audio signal processing method performed by the audio signal processing apparatus includes determining whether a line of sight between a render item (RI) corresponding to an audio element and a listener is visible, based on a bitstream, in response to a case where the line of sight is invisible, generating an audio signal by rendering a diffraction-type RI corresponding to the RI, and outputting the audio signal.
