针对现有空间音频增强算法忽视残余干扰空间线索的问题，提出基于多输出波束形成的保方向算法，在保持估计误差性能的同时，更好地保留残余干扰的空间线索。
AI 中文摘要
空间音频信号增强（SASE）旨在将期望声场从干扰和噪声中分离出来，同时保留其空间线索。然而，现有算法对保留残余干扰的空间线索关注有限，这降低了它们在实际应用中的有效性。本文提出了一种基于多输出波束形成的保方向SASE算法。该算法在提取期望声场的同时，保留期望声场和残余干扰声场的空间线索。仿真研究表明，在估计误差方面，所提算法达到了与现有SASE算法相当的性能，同时在噪声和混响环境中，它更好地保留了感兴趣区域内残余干扰的空间线索。
英文摘要
Spatial audio signal enhancement (SASE) aims to separate a desired soundfield from interference and noise while preserving its spatial cues. However, existing algorithms pay limited attention to preserving the spatial cues of the residual interference, which reduces their effectiveness in practical applications. In this paper, we propose a direction-preserving SASE algorithm based on multi-output beamforming. The proposed algorithm extracts the desired soundfield while preserving the spatial cues of both the desired soundfield and the residual interference soundfield. The simulation study shows that the proposed algorithm achieves performance comparable to the existing SASE algorithm in terms of estimation error, while it better preserves the spatial cues of the residual interference within a region of interest, in a noisy and reverberant environment.
