Software Package taX

taX is a software package for building and solving low-order (thermo-)acoustic network models. With taX, you can  determine mode shapes and stability of eigenmodes of networks of arbitrary topology. Furthermore, you can compute frequency responses or scattering matrices of duct elements. taX has a graphical user interface and convenient post-processing routines and comes with a library of frequently used network elements, which can easily be customized or extended. Find the code on and its documentation at

If you want to use taX, please contact Prof. Wolfgang Polifke
