Graphical visualization is important for acousticians to define whether a material can or cannot be installed in a room with desired response, for example. After

For simulating sound propagation in large enclosed spaces such as cathedrals, methods other than wave-based are required. In F.A.S.E.S, a modified image-sources method is used

F.A.S.E.S considers dynamic and bulk viscosities in its finite difference schemes in order to implement the phenomena due to air absorption. Above, the impulse response

After voxelizing the input models, user can choose the slices coordinates in cartesian directions x, y and z, then click on the option Plot ->

As it can be seen, F.A.S.E.S accepts enclosed spaces with arbitrary geometries, such as the L-shaped room in the figure. After user loads a project

F.A.S.E.S is an upcoming C++/Lua Fast Acoustics Solver for Enclosed Spaces, either for obtaining room impulse reponses (RIRs) or evaluation of impulse responses in other
