结合声源分离的两通路立体声音乐信号向上混合方法OA

Conventional stereo upmixing methods typically operate on audio content within the time-frequency domain.However,in complex musical mixtures,the overlapping of multiple sources in this domain often leads to biased estimation of correlation and source location parameters.To mitigate this issue,this paper proposes a two-path stereo music upmixing method incorporating source separation,built upon the existing frequency-domain upmixing framework.By decomposing the mixed music signal into multiple constituent sources and processing them individually,the proposed method effectively reduces interference caused by time-frequency overlap during parameter estimation.Subjective listening tests demonstrate that,compared with several representative upmixing methods and an ablation variant without the source separation module,the proposed approach achieves superior performance in terms of overall perceived audio quality.
