 Recent acoustic analyses have focused on [[http://​www.music.mcgill.ca/​~gary/​vti/​|vocal-tract influence in woodwind instrument performance]] and fluid-structure interactions in wind instrument systems. ​ My acoustic modeling work is concerned with the characterization of the various interdependent components of a music instrument system, such as the mouthpiece, air column, and toneholes of a clarinet. This approach is commonly referred to as "​physical modeling"​. A discrete-time technique called "​digital waveguide synthesis"​ is often used to efficiently and accurately implement these acoustic models. Recent synthesis developments have been focused on aspects of woodwind instrument toneholes, conical air columns, vocal tract influences, and reed/​mouthpiece interactions. Several human-computer interfaces have been developed in the course of this research for the purposes of experimenting and performing with the real-time synthesis models. Recent acoustic analyses have focused on [[http://​www.music.mcgill.ca/​~gary/​vti/​|vocal-tract influence in woodwind instrument performance]] and fluid-structure interactions in wind instrument systems. ​ My acoustic modeling work is concerned with the characterization of the various interdependent components of a music instrument system, such as the mouthpiece, air column, and toneholes of a clarinet.

-Acoustic and psychoacoustic ​experiments also play a role in this research. In many instances, acoustic theory must be validated by experimental measurements. ​Psychoacoustic ​studies can aid in the development of efficient and convincing synthesis models by helping identify acoustic features of a system which have less perceptual importance for human listeners.+Acoustic and perceptual ​experiments also play a role in this research.

 To support the design and implementation of real-time synthesis models, a software synthesis environment called the [[http://​ccrma.stanford.edu/​software/​stk/​|Synthesis ToolKit in C++ (STK)]] has been developed in collaboration with Perry Cook at Princeton University. STK is a set of open source audio signal processing and algorithmic synthesis classes written in C++. The ToolKit was designed to facilitate rapid development of music synthesis and audio processing software, with an emphasis on cross-platform functionality,​ real-time control, ease of use, and educational example code. To support the design and implementation of real-time synthesis models, a software synthesis environment called the [[http://​ccrma.stanford.edu/​software/​stk/​|Synthesis ToolKit in C++ (STK)]] has been developed in collaboration with Perry Cook at Princeton University.
