help with adding samples.

hi, I hope im asking this in the right place. im new to audio editing and want to learn one specific thing.
I have a few videos of duelling fight scenes. but the is a very audible clack from the weapons whilst duelling.
I want a way of automatically finding and replacing every clack with a sample file. is this possible and if so how? thanks

The clacks will be easiest to spot using Audacity’s spectrogram view …

Substituting them with another sound will have to be done manually, (i.e. individually).
