1. A binaural rendering method for multichannel audio signal in time domain, comprising:
identifying an early reflection and a late reverberation for a binaural rendering; and
performing binaural rendering to convert a multichannel signal to a stereo signal based on the early reflection and the late reverberation, and
wherein the multichannel audio signal corresponds to a QMF domain, and
wherein an audio signal of the QMF domain and a direct sound and an early reflection sound of the QMF domain are processed according to a bandwise partitioned fast convolution for the binaural rendering.
