what is siren-simulator fr?

Siren Simulator is a desktop application written in C++ that lets you explore how rotary mechanical warning sirens work in real time, the kind used for tornado alerts and civil defense. It models a rotor and stator chopper, an induction motor that spins the rotor, a forced air blower, the horn shape, stereo sound direction, and how the sound travels outdoors, all combined into one interactive tool you can experiment with. The application is built using the same graphics engine that powers a separate project called Engine Simulator, but the siren model and interface here are original. The README is clear that this is an experiential, simplified acoustic simulator built on physically motivated models for airflow, pressure, motor load, horn response, and sound propagation. It is not a computational fluid dynamics package, a measurement instrument, or a certification tool. The simulator generates its siren sounds procedurally from the overlap of rotor and stator ports rather than playing back recordings. You can configure single, dual, triple, or quad tone setups sharing one shaft, adjust port counts, phase, and opening, and tune motor behavior like spin up, coast down, torque, and electrical supply frequency. Blower settings control build up time and plenum pressure, while horn settings cover shape, throat and mouth size, length, flare, and material. Sound can be played back in omni or directional mode with adjustable bearing, distance, reverb, and outdoor environment profiles, and you can trigger standard signal programs such as Fire Hi/Lo, Attack, Alert, Manual, and Stop. Full configurations can be saved and loaded as human readable preset files. Running it requires Windows 10 or 11, Visual Studio 2022 with the Desktop development with C++ workload, CMake 3.16 or newer, and Git. You clone the repository with its submodules, configure the build with CMake, and build the target with Visual Studio's toolchain, after which the compiled executable launches directly with its required assets copied alongside it.
