Yes, this would be useful in “long narration audio recording”
Because when you’re recording a book, you need to hit PAUSE a lot. But hitting P on a traditional keyboard makes way too much sound.
So, I use a “Capacitive touch switch” (e.g. a metal plate that triggers when you merely touch it with your fingers)
The problem with these buttons is, it’s too easy to touch it twice. So i need to ignore the second touch. Or rather, I have to set it up so that a “touch” ONLY means “play,” never “resume”
I know what a capacitive touch switch is. I don’t know what that’s got to do with Audacity. I’m getting the impression that you have tried to rig up a capacitive touch switch to your computer to act as an alternative “P” key, but it is not producing a clean single press signal.
