Real-Time Multiple Source Acoustic Impulse Response Generation for Anomaly Detection
(НН ФТІ, КПІ ім. Ігоря Сікорського, 2025) Terletskyy, О.; Trushevskyy, V.
This paper introduces a real-time method for simulating sound propagation using ray tracing, aimed at cybersecurity for detecting and analyzing acoustic threats. By modeling the behavior of acoustic waves in virtual environments, the approach accurately captures reflections, diffractions, and reverberations, enabling tasks like audio-based anomaly detection and spatial audio analysis in secure areas. It supports multiple simultaneous sound sources, merging their effects into a cohesive acoustic model. The combination of impulse response generation with real-time convolution allows for detailed acoustic profiling that adapts to environmental changes, enhancing situational awareness. This method lays the groundwork for advanced acoustic monitoring systems, with applications ranging from secure communications to threat detection. Results confirm its capability to simulate complex acoustic interactions with high accuracy and real-time performance, making it a powerful tool for audio surveillance and cybersecurity.
