cant record windows audio

Probably what is happening in that case is the interface itself is changing it’s routing rather than the app doing it. Making it more like Real-time direct monitoring. That is obvious the best case if your interface can do it. ADAT and Spidiff won’t color the sound for recording since it’s all digital but maybe the clocking might come into play. Analogue however between two interfaces, passes through the DA of the first interface back to the AD of the second interface.

So the ideally, in terms of low latency, it would be

  • audio interface internal routing. (best option)


  • ADAT or digital routing. (2nd option)


  • Audio cables. (last resort)

If you don’t mind adding some latency you can use VoiceMeeter.
