Digital modeling of bridge driving-point admittances from measurements on violin-family instruments. In: Bresin R, Askenfelt A, editors. Proceedings of the Stockholm Music Acoustics Conference 2013. Berlin: Logos Verlag; 2013. p 101-108.http://hdl.handle.net/10230/23667We present a methodology for digital modeling of D-dimensional driving-point bridge admittances from vibration measurements on instruments of the violin family. Our study, centered around the two-dimensional case for violin, viola, and cello, is based on using the modal framework to construct an admittance formulation providing physically meaningful and effective control over model parameters. In a first stage, mode frequencies and bandwidths are estimated in the frequency domain via solving a non-convex, constrained optimization problem. Then, mode amplitudes are estimated via semidefinite programming while enforcing passivity. We obtain accurate, low-order digital admittance models suited for real-time sound synthesis via physical models.application/pdfeng© 2013 Esteban Maestre et al.
