Abstract: A method and apparatus for performing binaural rendering of an audio signal are provided. The method includes identifying an input signal that is based on an object, and metadata that includes distance information indicating a distance to the object, generating a binaural filter that is based on the metadata, using a binaural room impulse response, obtaining a binaural filter to which a low-pass filter (LPF) is applied, using a frequency response control that is based on the distance information, and generating a binaural-rendered output signal by performing a convolution of the input signal and the binaural filter to which the LPF is applied.

Abstract: Disclosed is a binaural rendering method and apparatus for decoding a multichannel audio signal. The binaural rendering method may include: extracting an early reflection component and a late reverberation component from a binaural filter; generating a stereo audio signal by performing binaural rendering of a multichannel audio signal base on the early reflection component; and applying the late reverberation component to the generated stereo audio signal.

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.
