I-Simpa | An Open Source software for 3D sound propagation modelling

I-Simpa is a C++ library. I-Simpa has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

I-Simpa is a graphical user interface (GUI) developed to host three-dimensional numerical codes for the modeling of sound propagation in complex geometrical domains. Although I-Simpa is well adapted for energetic models (ray-tracing, sound-particle tracing, theory of reverberation…), it can be extend to use ondulatory approaches. I-Simpa alone is not a calculation software, but is equivalent to a pre and post-processor for acoustic codes. One or more numerical codes must be added in order to obtain a fully functional system. At the present time, I-Simpa is delivered with two codes (TCR and SPPS, see information here). Classical applications are room and building acoustics, environmental noise and industrial noise, but it can be easily extend to other applications concerning the sound propagation in 3D environments (interior of vehicle, sound in cavities…).
