标题： Accelerated Interactive Auralization of Highly Reverberant Spaces using Graphics Hardware

摘要： 交互式声学听觉化使用户能够实时探索虚拟声学环境，从而实现对无法进入、声学特性已改变或难以访问的音乐厅或历史礼拜空间（HWS）的声学再现。 交互式声学合成需要将输入信号与一组模拟空间时间声学响应的合成滤波器进行实时卷积。 音乐厅和HWS的声学特征都表现为较长的混响时间，导致合成滤波器包含大量滤波器抽头。 因此，卷积过程可能计算量较大，引入显著延迟，限制了听觉化系统的实时交互性。 本文介绍了基于多通道扬声器的实时听觉化系统的实现。 该系统能够使用GPU加速实时合成高度混响空间的声学特性。 本文比较了传统的基于CPU的卷积与GPU加速的卷积，结果表明后者可以以显著更低的延迟实现实时性能。 此外，该系统将声学合成与GPU上的声学反馈消除集成在一起，创建了一个统一的基于扬声器的听觉化框架，最大限度地减少了处理延迟。 显示英文摘要

摘要： Interactive acoustic auralization allows users to explore virtual acoustic environments in real-time, enabling the acoustic recreation of concert hall or Historical Worship Spaces (HWS) that are either no longer accessible, acoustically altered, or impractical to visit. Interactive acoustic synthesis requires real-time convolution of input signals with a set of synthesis filters that model the space-time acoustic response of the space. The acoustics in concert halls and HWS are both characterized by a long reverberation time, resulting in synthesis filters containing many filter taps. As a result, the convolution process can be computationally demanding, introducing significant latency that limits the real-time interactivity of the auralization system. In this paper, the implementation of a real-time multichannel loudspeaker-based auralization system is presented. This system is capable of synthesizing the acoustics of highly reverberant spaces in real-time using GPU-acceleration. A comparison between traditional CPU-based convolution and GPU-accelerated convolution is presented, showing that the latter can achieve real-time performance with significantly lower latency. Additionally, the system integrates acoustic synthesis with acoustic feedback cancellation on the GPU, creating a unified loudspeaker-based auralization framework that minimizes processing latency.
