The Wind Instrument Acoustic Toolkit

This toolkit consists of a package of computer programs useful for researchers in wind instrument musical acoustics and eventually, the wind instrument designer as well. It includes both simulation and measurement capabilities. Researchers from musical acoustics laboratories around the world are invited to collaborate in its development to keep it up to date with the latest theoretical results. The capabilities of the software include:

  1. the calculation of linear input impedance from a geometry definition using either a one-dimensional transmission-matrix (TM) method or multimodal method (MM);
  2. optimization routines for the design of wind instrument prototypes;
  3. processing of measurement data for comparison with simulation results;
  4. automatic generation of reports for easy incorporation into publications and/or web sites.

Other suggestions are welcome.

Important notes:

To get started, you can look at the Examples directory.
