Abstract / Description of output

In this paper, we develop real-time applications including virtual instruments and plate reverb using the Kirchhoff plate model with loss and tension terms. Finite-difference time-domain (FDTD) methods are employed, and they are
implemented on central processing units (CPUs) and optimized by loop unrolling or advanced vector extensions (AVX), enabling these programs to be executed in real time at fast speeds. applications such as virtual plate instruments and plate reverb using FDTD schemes are developed as puredata (Pd) externals which can serve as objects in puredata, a real-time graphical programming environ-
ment for audio and graphics. In these applications, multiple inputs (excitation or audio signal) and outputs whose positions are free to change in real time are allowed, and physical parameters can be dynamically manipulated in
real time, allowing users the ability to produce both realistic sound and new sounds not possible to generate in the real world. Additionally, these Pd externals can also be used as modules to build Pd patches, which provides more
possibilities for experimental artists.
