The Shotcut Tutorial entitled “Recording a Voice Over” (URL: shotcut.org/tutorials/) is where I originally encountered “Direct Show”.
According to Sauron ’ “Direct Show” for voice overs was … renamed Audio/VIdeo Device since many users do not know what DirectShow is. ’ (See my post Reset Select Audio to initial state ).
So I found the tutorial helpful, but very misleading.
