Sonification Using Digital Waveguides and 2- and 3-dimensional Digital Waveguide Mesh
نویسندگان
چکیده
We describe a method of auditory display of complex data, object identification, and classification using digital waveguides and waveguide mesh. Our overall goal is to distinguish highly dimensional data sets from one another in such a way that reveals meaningful differences in a particular context. In this paper we provide a summary of the application of waveguide and waveguide mesh architectures to sonification, and demonstrate the digital waveguide, 2and 3-dimensional mesh in a variety of sonification tasks.

Reducing the dispersion error in the digital waveguide mesh using interpolation and frequency-warping techniques
The digital waveguide mesh is an extension of the onedimensional (1-D) digital waveguide technique. The mesh can be used for simulation of twoand three-dimensional (3-D) wave propagation in musical instruments and acoustic spaces. The original rectangular digital waveguide mesh algorithm suffers from direction-dependent dispersion. Alternative geometries, such as the triangular mesh, have been ...

The main emphasis in developing DOS has been on achieving low crosstalk (CT). CT in the order of -30 dB is acceptable in conventional DOS and below that value is hard to achieve. Relatively low drive voltage (or power requirements) is also necessary to optimized DOS. This paper depicts the design of Y-branched digital optical switches (DOS) with optimized on-chip area coverage, reduced driving ...

Interpolated and warped digital waveguide mesh algorithms have been developed to overcome the problem caused by direction and frequency-dependence of wave travel speed in digital waveguide mesh simulations. This paper reviews the interpolation methods applicable in the two-dimensional case. The bilinear interpolation technique and two other approaches are briefly recapitulated. The use of 2-D q...
