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: A method of detecting a sound event includes receiving sound signals using one or more directional microphones, extracting a time interval of each of the sound signals, extracting time information and an azimuth of a sound event included in the sound signals during the extracted time interval, mixing the sound signals received from the directional microphones using the extracted time interval, and determining a direction of the sound event generated at a specific time from a mixed sound signal obtained through the mixing using the extracted time information and azimuth of the sound event.

Abstract: Provided are an encoding method of a multichannel signal, an encoding apparatus to perform the encoding method, a multichannel signal processing method, and a decoding apparatus to perform the decoding method. The decoding method may include identifying an N/2-channel downmix signal derived from an N-channel input signal; and generating an N-channel output signal from the identified N/2-channel downmix signal using a plurality of one-to-two (OTT) boxes. If a low frequency effect (LFE) channel is absent in the output signal, the number of OTT boxes may be equal to N/2 where N/2 denotes the number of channels of the downmix signal.
