George Tzanetakis, from University of Victoria (Canada), gives a talk on "Physical Modelling Beyond Sound Synthesis: three case studies" on Thursday October 24th at 15:30h in room 52.321.

Abstract: Physical modelling synthesis refers to a set of sound synthesis techniques in which the generated sound is computed as the output of a set of equations describing the actual physics of sound production of musical instruments. It can be viewed as a virtual simulation of the physical world. Physical modelling synthesis has many advantages including rich realistic sound, meaningful control parameters (such as the length of a string), and computational efficiency. One of the main challenges is that, similarly to actual acoustic music instruments, the control of physical models is not trivial as there are many regions of the parameter space that produce undesirable output sound. In this talk I will describe three case studies of combining concepts from different research areas (namely New Interfaces for Musical Expression and Music Information Retrieval) and physical modelling synthesis that attempt to address this control issue:

  1.  the SoundPlane which is a multi-touch pressure sensitive surface  that provides rich control possibilities
  2. the hybrid Gyil (an African Xylophone from Ghana) in which the buzzing gourds are physically modeled on a computer but the actual wooden bars are retained and
  3. Vivi, a virtual violinist that is taught how to bow a physical violin model similarly to how a beginner player learns to bow an actual acoustic violin.
