DownloadART is a flexible simulation framework for wind instruments. It includes a growing library of modelling elements. So far bore discontinuities, branches, tone holes, cylindrical and conical tubes, Bessel horns and bent tubes are available for frequency domain modelling.
In the time domain generic bidirectional propagation elements, scattering elements, fractional delays, convolution with reflection functions and general z-domain networks are available and can be described using MuParserX expressions. Cylindrical and conical ducts can also be defined based on their geometry.
Available models and their parameters can be enumerated and combined to form simulators for complex acoustical structures. Parameters can be specified symbolically by expressions containing other parameter values or global variables.
Dependencies between parameters are resolved at run time. However, MuParserX expressions are compiled at design time. Zero-delay loops are detected and reported.
Features
- The library contains an application interface for developers and comes with useful sample applications
- The application interface accepts symbolic expression input for all parameters at runtime
- All expressions are only re-evaluated when needed -> efficient for optimisers
- Simulation models are self documenting. Usage information is retrieved by application
- Application programs do not need to be recompiled when the library gets new features
- Multi-modal frequency domain simulation including branches and tone holes
- Time domain modeling with predefined and user defined (generic) propagation elements
