Here is what I currently am using for my audio/visual equipment in my home studio.
My microphone. I got two of these for equal quality when I have guests.
What I plug all of the audio into (mics, guitar, etc.) to mix and send audio to computer and/or phone.
I also have this camera but I’ll switch between my cell phone (Samsung Galaxy S23+ Ultra) or this.
Rode PSA1 Microphone Boom
This is the boom stand for my microphone.
This cable is about the only other things you’ll need for equipment.
