用声学仿真替代真实测量,高效评估音频算法性能
Room-acoustic simulations as an alternative to measurements for audio-algorithm evaluation
- 采用声学仿真替代昂贵的实地测量数据进行算法评估
- 基于物理的波场模拟与实测结果一致,几何声学模拟则不匹配
- 适合需要快速验证算法在多种声学环境表现的研究者
音频信号处理与音频机器学习算法广泛应用于智能设备、可穿戴产品和娱乐系统。算法开发通常需通过严格评估以证明其有效性及超越现有水平。理想情况下,评估应覆盖多样化的应用场景和声学条件,但实际受限于成本与时间,数据集规模小且多样性不足。本文探讨使用房间声学仿真替代真实测量来评估ASP/AML算法的可行性。我们对比了三种算法在实测数据与三种不同仿真引擎生成数据上的表现,评估仿真结果与实测的一致性。研究比较了基于数值波动的求解器与两种几何声学仿真器。结果显示,数值波场仿真对所有三类算法的评估结果均与实测高度一致,而几何声学仿真则无法可靠复现实测结果。
原文摘要 · Abstract (English)
Audio-signal-processing and audio-machine-learning (ASP/AML) algorithms are ubiquitous in modern technology like smart devices, wearables, and entertainment systems. Development of such algorithms and models typically involves a formal evaluation to demonstrate their effectiveness and progress beyond the state-of-the-art. Ideally, a thorough evaluation should cover many diverse application scenarios and room-acoustic conditions. However, in practice, evaluation datasets are often limited in size and diversity because they rely on costly and time-consuming measurements. This paper explores how room-acoustic simulations can be used for evaluating ASP/AML algorithms. To this end, we evaluate three ASP/AML algorithms with room-acoustic measurements and data from different simulation engines, and assess the match between the evaluation results obtained from measurements and simulations. The presented investigation compares a numerical wave-based solver with two geometrical acoustics simulators. While numerical wave-based simulations yielded similar evaluation results as measurements for all three evaluated ASP/AML algorithms, geometrical acoustic simulations could not replicate the measured evaluation results as reliably.
