Hello, I'm not sure what you mean. gpuRIR uses the image source method and obtains the RIRs you could expect from this method. Indeed, ray-tracing methods are not the most accurate at low frequencies and wave- or mode-based techniques might be better, but I don't think there's anything that can be done in the library about it.
