Gear Performance: Capturing Video & Audio Simultaneously

Hi!

Can I get some guidance on creating performance / stream videos Like this:

I want to be able to record video and capture quality audio simultaneously.

first i need a camera Thinking about doing it with a single dslr set up. Going the DSLR route. Thinking I can use it to get back into my old photography hobby too.

Is there software, cameras you would recommend that can help achieve this.

You’ll need a sound card a mixer a video capture card and look this up.
