1. An audio signal processing method performed by an audio signal processing apparatus, the method comprising:
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;
in response to a case where the line of sight is visible, generating an audio signal by rendering the RI without creating the diffraction-type RI; and
outputting the audio signal.
