提出了一种基于独立分量分析（伊卡）的盲源分离（BSS）方法来分析和控制立体声音频信号的源定位。虽然分离的逆系统补偿由伊卡引起的失真作为立体空间特性的重建，但是该技术不足以分析定位，因为它同时实现失真的补偿和空间特性的重建。因此，我们有效地分析了空间特性分为两个步骤的补偿：单声道输出的失真补偿和其重建的空间特性。此外，我们通过修改分析的空间特征来控制每个源的定位。结果表明，所提出的方法可以适用于立体声信号组成的两个以上的来源。
We propose methods to analyze and control source localization of stereo audio signals using blind source separation (BSS) based on independent component analysis (ICA). Although an inverse system of separation compensates distortion caused by ICA as reconstruction of stereo spatial characteristics, this technique is insufficient to analyze localization because it achieves compensation of distortion and reconstruction of spatial characteristics simultaneously. Thus we analyze spatial characteristics effectively by dividing the compensation into two steps: monaural-output compensation of distortion and its reconstruction of spatial characteristics. Additionally, we control the localization of each source by modifying the analyzed spatial characteristics. It is shown that the proposed method can be applied to stereo signals consisting of more than two sources.
