Abstract

The dynamics of musical instruments are simulated to approximate their waveform for digital synthesis. In addition to this largely deductive process, the development of the model also includes an inductive phase of listening where the sound of the existing instrument and the digital sound from the model are compared. When the desired outcome is known (i.e, a clarinet), the ear can fine-tune the model for perceptual dimensions such as timbre. Yet one of the primary advantages of physical modeling is to generate novel sounds from virtual geometries and dynamics that do not necessarily correspond to existing instruments or performance traditions. 3d printing is discussed as a means to quickly manufacture these novel acoustic instruments with limitations that are rapidly receding; now we can quickly hear both the digital synthesis derived from physics and the physical object printed from those very models.
