Abstract: An apparatus and method for generating a wave field synthesis (WFS) signal in consideration of a height of a speaker are disclosed. The WFS signal generation apparatus may include a waveform propagation distance determination unit to determine a propagation distance of a waveform propagate from a sound source based on a height of a speaker, and a WFS signal generation unit to generate a WFS signal corresponding to the speaker using the propagation distance of the waveform.

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.
