The Image Source Method (ISM) is one of the most employed techniques to calculate acoustic Room Impulse Responses (RIRs), however, its computational complexity grows fast with the reverberation time of the room and its computation time can be prohibitive for some applications where a huge number ...

Repeatedly convolving rectangular impulse responses produces triangular, then Gaussian-like impulse responses. And finally, the frequency response can be calculated using NumPy’s freqz function, as seen in Figure 16. The response is shown in Figure 15. Figure 15. Convolving a sinc3, 50 Hz ...
