I don't know why you are editing because the first version was fine.
For me, all the pauses and "er"s were very cringy I originally thought that doing it in one take would be a good idea..
It was only up for a couple of days when it was up originally.. what made you want to download it in the first place?
Thanks, I was just curious because a friend who makes violin bows has asked me to build what sounds like the very same thing that your customer wants, although without the same level of automation and speed constraints.
What you need is a Fast Fourier Transform to tell what frequencies are present in your signal.
You may need a steep low pass filter to get this working nicely.
Not necessarily, depending on the tone. When I asked about a Stamp detecting a recorder (flute) note, I got the same answers about harmonics and FFTs, so I put it on the back burner. Well I tried it today and it worked great on my first attempt... frequency range 500-1000 hz. OP Tom was asking about 440 hz, so I say give it a whirl. Quite fun to play with actually, and now I'm experimenting with Stamp-generated harmony.

Musicians take their violin bows very seriously. My friend's husband is a professional musician, LA Philharmonic, studio recording and such. I met up with them in Paris one April, several years ago. I was on a cheap jaunt, biking through Europe and running the Paris marathon. My friends were there on "official business" to get two vintage violin bows appraised. Just the bows. Four star hotels, fancy meals, the works. Their whole trip was a tax writeoff. Some people... are much smarter than me.

Nothing quite so exotic. Mostly eastern north american maple, hickory and other close grained hardwoods.
Cheers,

Most people.
