Reverberation is an essential effect for sound design and music production, and commercially available software offers an unprecedented range of solutions for artists. Plate reverberation represents an attractive choice as the modal density of large plates is constant over the audible range, creating a uniform response in the frequency domain. However, available plug-ins rely on either sampled impulse responses or simple delay algorithms. In this paper, a pure physical model of a rectangular plate is used at the core of a real-time effect plug-in. The user has a choice of intuitive parameters to select the dimensions of the plate, the tension, and decay ratios. The input and output positions can be changed dynamically, during the runtime of the simulation. This represents a clear improvement over static algorithms based on impulse responses. Optimisation of the model using CPU vector intrinsic is demonstrated, allowing real-time computation of large-scale plate reverbs on consumer hardware using a standard plugin architecture.
