...ying fractional delay (TVFD) filter [9]. Other nonlinear string instrument models include the slap-bass model of Rank and Kubin [10] and the nonlinear commuted synthesis model for the violin by Smith =-=[11]-=-. A model with a memoryless nonlinearity for the kantele, a traditional Finnish plucked string instrument, is presented in [12]. The linear digital waveguide has been extensively used for simulation o...

...esign of such intermediate representations based on a source-filter model. This model has been employed extensively in speech research [1], and has been integrated into both physical modeling methods =-=[3]-=- and sampling, or wavetable synthesis [4]. The basic motivation behind the use of this model is that most natural instruments, as well as human voice can be thought of as consisting of two fundamental...

...ion has been investigated further [156, 80, 75, 157]. Nonlinear synthesis methods for bowed stringed instruments and fret-string interactions or nonlinear boundary conditions have also been discussed =-=[158, 159, 160, 161]-=-. Nonlinear models relevant and interesting with regard to this thesis are the ones that consider the synthesis of phantom partials. Many synthesis models for this phenomenon have been proposed recent...

For efficient sound synthesis purposes, another approach can be taken, where commuted waveguide synthesis is possible =-=[252]-=-. In it, each period of string vibration is given a separate wavetable excitation. Due to the nonlinearity of the physical phenomenon, inclusion of both the excitation and the body response in the wav...

...6), the same author presented a system in which bow velocity, force, and position can be used as inputs to a “bow-string interaction model” that drives the “commuted-synthesis model” described above (=-=Smith 1997-=-). The system is comprised of a “single-hair” bow model that excites a string model, according to the input of the three bowing parameters. The output from this string model is read by an “impulse pri...
