Real-Time FPGA and GUI-driven Auralization of Geometry and Material Variations of the Piano

这一续订应用是基于正在进行的DFG项目使用物理建模实时实施乐器的现场可编程门阵列，现在专注于将用于音乐指令声音产生的微分方程式的完全工作的实时实施在FPGA硬件上应用于乐器制造商和车间。基于该系统的成功专利和对行业应用的追求，世界上最大的仪器制造商之一施坦威父子公司热衷于将该方法纳入他们的仪器改进过程中。在这里，一架完整的钢琴将被实时模拟，以便乐器制造者所需的所有几何和材料参数也可以实时变化。因此，与施坦威父子公司的开发部门密切合作，开发了一种软件，使用户可以轻松地更改这些参数，并将其用于钢琴的日常改进和修改过程。因此，施坦威建造了两架测试钢琴，并根据麦克风阵列对钢琴辐射的录音以及高速摄像机对钢琴弦的录像的测量结果不断对其进行修改。

This renewal application is based on the ongoing DFG Project Real-time FPGA Implementation of Musical Instruments using Physical Modeling an now focusses on applying the fully working real-time implementation of differential equations for sound production of musical instruemtns on an FPGA hardware to instrument builders and workshops. Based on the successful patent of the system and the seek for industry utilization, one of the worlds largest instrument builders, Steinway & Sons, was enthusiastic to include the method in their process of instrument improvement. Here a complete piano is to be simulated in real-time so that all geometrical and material parameters needed by the instrument builder can also be varied in real-time. Therefore, in close cooperation with the development division of Steinway & Sons, a software is developed which makes it easily possible for a user to change these parameters, and which is then used in the daily process of piano improvement and modification. Therefore, Steinway builts two test pianos and modifies them constantly according to results of measurements made by a microphone-array recordings of the piano radiation, as well as high-speed camera video recordings of the piano strings.
