How to record Windows 10 sound without a microphone?
For example, I have an application that makes sound, and I need to record this sound without noise (microphone).

Answer 1

In the RMB tray on the sound icon, there is a mixer and sound settings.
If this is not enough (and it is often not enough), then there is a wonderful virtual audio cable thing (some features are paid)
and a bunch of alternatives https://alternativeto.net/software/virtual-audio-cable/
