DSP Seminar
This week's DSP seminar will be presented by Jack Perng.  Jack is a Ph.D. student in physics, and is studying musical acoustics.; He will present work he has undertaken on harpsichord modeling. The seminar will take place in the CCRMA classroom (Knoll 217) at 3:15 on Friday, Oct 1. Abstract follows


Physical Modeling of the Harpsichord Plectrum

Jack Perng

The harpsichord has a distinct pluck tone not mistaken with any other instrument.  In the attempt to synthesize the harpsichord sound, the plucking excitation is of great importance. Previous excellent harpsichord synthesis methods have opted to use extracted recorded excitations. A physical model of the pluck excitation, however, provides freedom in controlling physical parameters, such as the plectrum stiffness or dimensions. ;Previous harpsichord plucking models will be reviewed and discussed. I will also present my revised harpsichord plectrum model and discuss the preliminary simulation results.
