摘要： 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.

摘要： An encoding apparatus and a decoding apparatus in a transform between a Modified Discrete Cosine Transform (MDCT)-based coder and a different coder are provided. The encoding apparatus may encode additional information to restore an input signal encoded according to the MDCT-based coding scheme, when switching occurs between the MDCT-based coder and the different coder. Accordingly, an unnecessary bitstream may be prevented from being generated, and minimum additional information may be encoded.

摘要： A method and system for processing an obstacle effect in a virtual acoustic space are disclosed. The method includes receiving a parameter for an obstacle candidate plane extracted from spatial information, determining, in response to the parameter, whether the obstacle candidate plane is an obstacle related to a path between a position of a virtual sound source and a position of a user, and applying a sound effect according to the obstacle to an audio signal when the obstacle candidate plane is the obstacle. The obstacle candidate plane is a plane of an object that may become the obstacle in a sound propagation path between the virtual sound source and the user.
