摘要

本文提出了声源定位系数编码中的双耳解码方法，以降低编码复杂度。所提出的双耳解码是通过将空间参数生成的多通道音频信号的增益因子与频域的HRTF系数进行卷积来实现的。与典型的时域双耳译码相比，该方法可将译码复杂度降低约90%。

Binaural decoding for efficient multi-channel audio service in network environment

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 %.
