Unfortunately it cannot.

[letnnn]

Is the inability to calculate distance a problem with this srp-phat algorithm itself or is it due to the limitations of the mini-microphone array?

[BrownsugarZeer]

SRP-PHAT itself can only get the direction where the sound come from.

When I tried to measure the distance to the sound source with the TDOA I found that his time delay could not be calculated at all, I'm guessing that it's not too small a separation from my mike array? What do you think? Thanks for your answer.

[BrownsugarZeer]

Usually the spacing of most microphone arrays is sufficient and there won't be such a problem. Since the description is insufficient so I cannot give an feedback, sorry.

Hi, here is the data related to my microphone array, 16KHz sampling rate, with such an array I am not accurate when calculating the latency results. Can you give me some suggestions? Thank you very much for your answer.

mics = torch.zeros((4, 3))
mics[0, :] = torch.Tensor([-0.02150, +0.03725, +0.059])
mics[1, :] = torch.Tensor([+0.02150, +0.03725, +0.059])
mics[2, :] = torch.Tensor([+0.02150, -0.03725, +0.059])
mics[3, :] = torch.Tensor([-0.02150, -0.03725, +0.059])

I don’t think there is anything wrong with this microphone array. Is it possible that there are uncertain factors in the experimental environment?
