Design of an Efficient Inharmonic Digital Waveguide Filter for Synthesis of Hand-bell Sounds
نویسندگان
چکیده
This paper addresses the use of an inharmonic digital waveguide (IDWG) filter as an efficient means to synthesize hand-bell sounds. The IDWG is obtained by inserting a second-order allpass filter to the feedback path of a waveguide string model. An automated iterative procedure for estimation of the allpass filter coefficients and the length of the delay line is proposed. Limitations of the devised design method as well as possible extensions are also discussed.

In this paper we present an analysis, modeling, and synthesis approach to bell sounds. Recorded bell sounds are first analyzed by high-resolution frequency-zooming modal estimation technique, where each partial is described typically by 2-3 submodes in order to include the warble characteristics of envelope beating in the partials. The bells are then modeled by inharmonic digital waveguides (DW...

Recent work has led to highly efficient physics-based computational models of wave propagation in strings, acoustic tubes, membranes, plates, and rooms using the digital waveguide filter, the 2-D digital waveguide mesh, and the 3-D tetrahedral digital waveguide mesh, all of which are suitable for real-time musical synthesis applications. A simple first-order nonlinear filter structure derived f...

This paper presents a model-based sound synthesis algorithm for the Chinese plucked string instrument called the guqin. The instrument is fretless, which enables smooth pitch glides from one note to another. A version of the digital waveguide synthesis approach is used, where the string length is time-varying and its energy is scaled properly. A body model filter is placed in cascade with the s...
