Mesh2HRTF was developed at the Acoustics Research Institute as an open source project aiming at providing an easy-to-use software package for the numerical calculation of HRTFs. It targets researchers in the field of binaural audio, however the code for the boundary element method (BEM) can be used in numerous applications where the 3D Helmholtz equations needs to be solved numerically.

In a Nutshell

Mesh2HRTF simply reads geometrical data, calculates the corresponding sound field and produces HRTFs. To support multiple computer platforms, the concept of Mesh2HRTF is to focus on a command-line tool, which forms the numerical core, i.e., an implementation of the 3-dimensional Burton- Miller collocation BEM coupled with the multi-level fast multipole method (ML-FMM), and to provide add-ons for existing cross-platform applications for the preprocessing of geometrical data and for the visualization of results.
