Abstract :
In this paper, we proposed the binaural decoding in sound source location coefficient coding to focus on the reduction of the complexity. The proposed binaural decoding is implemented by convolution between the gain factors of the multi-channel audio signals generated by the spatial parameters and the HRTF coefficients in frequency domain. Compared with the typical binaural decoding in time domain, the proposed method can greatly reduce the complexity as about 90 %.
