This paper presents a real-time method for simulating sound propagation using ray tracing techniques to generate impulse responses and modify sound playback through convolution processing. By modeling the behavior of acoustic waves in virtual environments, the approach makes it possible to reproduce realistic sound through accurate handling of re-
ections, diractions, and reverberations. To improve stability, a static-ray technique that captures the acoustic properties of the scene without the noise that typically comes from generating new rays every frame is introduced. The paper also presents a running index method for updating the impulse response continuously, which prevents artifacts during
auralization and ensures smooth playback. Together with real-time convolution processing, these contributions create an immersive audio experience that reacts dynamically to changes in the environment. The results show that the approach can eectively reproduce complex acoustic interactions, oering both high delity and responsiveness in real-time
audio rendering, and providing a solid foundation for future spatial audio applications in virtual reality and game design.
