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.

Abstract: Provided is a method and apparatus for generating an impulse response using ray tracing. The method of generating an impulse response may include calculating a number of rays reaching a receiver from a transmitter based on acoustic geometry information including a position of the transmitter and a position of the receiver disposed in a sound space, a maximum ray length or a sound space volume, and a radius of the receiver, tracing the rays using a path of the calculated rays, and generating an impulse response based on the traced rays.

Abstract: A method and apparatus for rendering an object-based audio signal considering an obstacle are disclosed. A method for rendering an object-based audio signal according to an example embodiment, the method includes identifying an object-based input signal and metadata for the input signal, generating a binaural filter based on the metadata using a binaural room impulse response (BRIR), determining, based on the metadata, whether an obstacle is present between a listener and an object, modifying the generated binaural filter when it is determined that the obstacle is present, and generating a rendered output signal by convolving the modified binaural filter and the input signal.
