AB  - The MPEG Surround standard includes two "native" binauralization modules for reproducing 3D audio content over headphones. In this paper, we present a novel and efficient Binaural Room Impulse Response (BRIR) modelling algorithm that extends their possibilities. This model is based on a parametric decomposition of the BRIR and is integrated within the subband domain implementation of the MPEG Surround binaural decoding stage. First we show that for impulse responses with room effects, our approach offers a significant reduction in terms of computational requirements compared to the native methods. Second, we report results from listening tests comparing different tradeoffs between complexity and quality. We show that using our method, the quality gracefully increases when the complexity increases.
