For those who don’t know, sounds like P and B and D are called “plosives,” and include a rush forward of air that shows up in recordings as kind of a low-frequency thunk. You can go buy a nice pop filter – which is basically just nylon stocking on a hoop – or you can make one yourself.
The difficult part tends to be attaching them to things so they stay in place. This one fits into a standard mic clip, which means no secondary noise transmission, and no futzing around with velco or whatever. Pop it into the clip, position it, and you’re done.
I’ve done some studio experiments with this new design, and it is dramatically better than my old version. I threw some intentionally super-severe popping of plosive sounds at it today (P-P-P-POW, P-P-P-POW, really punching those Ps as hard as I could), and where the old filter could only reduce them, this new design stopped three out of four outright. Under realistic conditions, it stopped everything. AND: it’s otherwise sonically transparent, so far.
So if you know anybody building their own equipment, well, here y’go, have a design. ^_^
