Windows software for re-routing audio (to a DAW, say)

[kvotchin]

Is there anything like this for Windows?

Or another way of going about it, if there is any other...

Of routing audio from a standalone audio program to a DAW, that is.

You could try VoiceMeeter Banana maybe.

VB Cable from the site that pekbro just posted. I use it to route windows audio into FL Studio to add EQ and compression etc
