PathRIR framework accelerates acoustic simulation by pruning ISM paths

By PulseAugur Editorial · [1 sources] ·

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

IMPACT This framework could lead to faster and more efficient acoustic modeling for applications like virtual reality and audio processing.

    PathRIR: Physics-Guided Acoustic Path Selection and Late-Tail Compensation for Fast Room Impulse Response Simulation

    arXiv:2607.23293v1 Announce Type: cross Abstract: Image-source-method (ISM)-based room impulse response (RIR) simulation is a useful and physically interpretable tool for acoustic scene modeling, but full-order ISM becomes computationally expensive as the reflection order and roo…
