How to include sound in video while not hearing it during recording

Depending on what kind of sound, there are various ways to include it in OBS Studio. From external microphones or usb sound mixers, mp3 or mp4 music, to internet radio or YouTube etc. Indeed have Audio Monitoring off (that is the default setting).
