I agree with your two main ethos statements. I’d love to collaborate on game design, but I have the same problem of never finishing game projects. I usually get stuck when it comes to art assets, 'cause I’m not an artist and I can’t afford to hire one.
EasyEffects has a real-time pitch filter that works for me. I don’t understand how it works, but I didn’t need to mess with audio routing, I set applications to use my mic and EasyEffects somehow still applies the filters.
