Really struggling to record video + sound on PC, can anybody steer me in right direction?

[Xuzo]

This is what I'm trying to acheive:

Record myself playing guitar with 3 microphones. They are USB condenser microphones plugged into my PC

One channel for voice in the middle, and 2 channels for right and left guitar (1 microphone on sound hole and one pointing at the neck)

This is for classical guitar, so no direct input into PC

After the recording is done, I want to be able to adjust the balance on the left and right guitar so it's mixed evenly in stereo.

I have OBS studio and Audacity, but will get whatever software I need.

How can I acheive this?

I´m not quite sure if it is possible to enable 3 USB condenser mics at the same time on a PC, possibly Voicemeeter (Windows Audio Router and FX Host Software) does the job. In Voicemeeter you have some virtual input and output channels you can define. Condenser mics definitely need phantom power (24-48V), which they are able to get via USB but surely this is not an ideal solution, the mic probably won´t be very loud (not enough gain by preamp through USB). More importantly recording on Windows/Windows Audio Driver you shouldn´t do. The problem is latency. If you have any FX/Plugin you want to enable additionally the latency will increase significantly with every step in the processing chain that it will become impossible to handle.
For recordings like that you will need an Audio interface with several (Mic) inputs. USB has not been designed to provide phantom power, usually you will use XLR mic inputs in the audio interface from which the mics get the power. The recording is usually done by a DAW (Digital Audio Workstation) like Cubase, Pro Tools, Reaper, Ableton, FL Studio and so on . The audio interface also provides ASIO Audio driver that almost have no latency so you can add a lot of instruments, devices and effects and you can for example monitor your recordings in real time.

The basics you can learn with millions of tutorial videos and articles. Just one example: https://youtu.be/u_qCh3TIk8w?si=Rfibt4CZRPu78zkv
