I wrote a small tool to gen tab from the guitar using your computer’s mic. It’s called Tabbyhack. It’s running at https://jzohrab.github.io/tabbyhack/
Copying from that video’s description:
I don’t know about you, but I really don’t like writing TAB. I find it tedious – I’ve used some tabbing products, but all I wanted was to play and have the computer make tabs for me. Hence Tabbyhack – it’s not perfect, but it’s good enough for simple situations. It runs in your browser, and it’s free. I figure it might be useful for teachers or guitar hackers who need some quick TAB.
I’ve only run it using my acoustic guitar, no idea if it will work for electric. But if anyone is looking for something stupidly simple like this, I present to you my stupidly simple offering.
Edit - I kind of lied – it doesn’t really generate TAB, but it gives you a good boost in getting it done.
