Researchers have developed PathRIR, a novel framework for accelerating Room Impulse Response (RIR) simulation. This method preserves the geometric structure of the Image-Source-Method (ISM) while intelligently selecting only the most acoustically significant paths. To compensate for the energy lost due to path pruning, PathRIR employs a lightweight multilayer perceptron to predict and generate a missing late-tail energy envelope. Experiments demonstrate that PathRIR significantly improves runtime efficiency compared to full-order ISM simulators, with minimal errors in waveform and decay characteristics. AI
