强大的并行硬件，如通用图形处理单元（GPGPU），现在正在成为一个可行的工具，音频工程研究，具有巨大的潜力，在应用程序涉及沉重的计算负载。一个特别感兴趣的领域是嵌入在全3D环境中的乐器的大规模音频速率物理建模合成。本文探讨了特定的测试情况下，定音鼓使用时域有限差分法（FDTD），这是适合并行化。介绍了定音鼓模型的组成部分，即膜和腔，以及与声场的耦合条件。FDTD方法，然后开发，特别注意在并行硬件的实施问题。Nvidia特斯拉架构的性能分析，仿真结果和声音的例子。
Powerful parallel hardware, such as general purpose graphical processing units (GPGPUs), is now becoming a viable tool in audio engineering research, with great potential in applications involving heavy computational loads. One particular area of interest is large scale audio rate physical modeling synthesis of instruments embedded in a full 3D environment. This paper explores the particular test case of the timpani drum using the finite difference time domain (FDTD) method, which is suitable for parallelization. The constituents of the timpani model, namely a membrane and cavity are introduced, as well as the coupling conditions to the acoustic field. FDTD methods are then developed, with special attention paid to implementation issues in parallel hardware. An analysis of performance on the Nvidia Tesla architecture, simulation results and sound examples are presented.
