When I was in high school I took a programming class that was exclusively in QBasic. I saved all the lesson programs I wrote at that time. Just found them a couple days ago. Mind you they are way more basic than what you're talking about with these libraries. You're welcome to have them if you want but it's a long shot at best since you're talking about stuff I never learned. The stuff I have is more of an intro to QBasic.

There are a few tutorials here http://www.petesqbsite.com/sections/tutorials … tutorials.shtml the site hasn't been updated for a long time but the links still work so you can get the tutorials.

8bit 22khz waves

was quite common 😉 because it didn't take so much space and it sounds okay.
If you want to go further I would recommend using a different language, because qbasic is a little bit slow in comparison to pascal/C/C++.
You will find yourself using assembler really quick.
