 Since 2012, we have engaged in a research collaboration with Dr. Esteban Maestre and Dr. Julius Smith (Stanford University) to investigate the design of violin and guitar body filters, parameterized from measurements,​ for sound synthesis models. This research has included: modal decomposition of measured driving-point admittances obtained by means of a novel frequency-domain algorithm for optimization of digital filters in parallel form; passive modeling of radiativity and admittance by projection of measurements over a common modal basis, and an efficient implementation of bridge reflectance and sound radiativity filters from a single bank of shared resonant filters. The results make it possible to synthesize in real time the sound of a specific violin or guitar, with many possible commercial applications. For example, this technology could be used to virtually audition, via an online interface, a set of instruments for sale in a shop. Since 2012, we have engaged in a research collaboration with Dr. Esteban Maestre and Dr. Julius Smith (Stanford University) to investigate the design of violin and guitar body filters, parameterized from measurements,​ for sound synthesis models.

-A recent collaboration with several researchers at Stanford and the Politecnico di Milano is focusing on the virtual restoration and resynthesis of a historically important violin, the 1716 “Messiah” by Stradivarius,​ which sits in Ashmolean Museum in Oxford, England and cannot be played because of its fragile condition.+A recent collaboration with several researchers at Stanford and the Politecnico di Milano is focusing on the virtual restoration and resynthesis of a historically important violin, the 1716 “Messiah” by Stradivarius,​ which sits in the Ashmolean Museum in Oxford, England and cannot be played because of its fragile condition.
