It's a nice Virtual Audio Mixer for Windows.
It's a nice start for just using a microfoon with radiodj, and stream to your listeners.
To make a tutorial for this is like inventing the wiel again.
Go to the Downloads and get the tutorial for Voicemeeter_UserManual.pdf or the program VoicemeeterSetup_v1050.zip.
