I am working on isolating a specific audio click in a factory type setting. After my initial analysis I determined that a 2-pole High Pass Filter set between 500 and 800Hz would work best for me.
The timing can be random on when the clicks occur due to human interaction. The shape of the click is a "spike" shape. I do not have the images with me on this workstation but I can get them next week if it helps. Thus the process is not completely automated as a user is inserting the connectors together however the goal is to limit human error so as little interaction with this implementation as possible is preferred.
There will always be 3 clicks. Click A and Click B are very pronounced but Click C is very quiet and up until now a very expensive camera system was used to capture Click C visually.

However I was curious as to what DSP hardware would be recommended for analyzing such waveforms in a fast and efficient manner.
Side Note: I am leaning towards IIR due to ease of use and tweaking if that is an incorrect assumption please correct me.
