Home recording fundamentals are the decisions that come before you buy anything: where you'll record, how the room behaves, and what order to set gear up in so it works the first time. Most beginners buy a microphone before they've thought about any of this, then wonder why the recording still sounds off.
This category covers room treatment on a renter's budget, cable and desk setup, gain staging, and the daily habits that keep a home studio usable instead of a pile of unplugged gear by week three.
If this isn't quite the right fit, Music Production for Beginners and Digital Audio Workstations cover closely related ground.
