Select for the interface to get at the streaming audio. Reaper has a legacy feature to use a separate audio interface for output from the main selected interface. (This gives you the streaming app audio on those channels.) Now assign a different pair of outputs (not the main) for an output from Reaper. Assign the main output to the return channels. This lets you connect to that single interface. Some audio interfaces have return channels. Workarounds for when the virtual audio device or your OS is incompatible: (Or if the streaming app lets you select an output device, select the virtual device there.)Īssign the input channels from that virtual device to a track in Reaper.Īssign your mixer output to your hardware device as usual.

Set the system output to the virtual device. This gives you access to all the I/O from all devices in the aggregate. You select the aggregate device in Reaper instead of one of the individule interfaces. This is done with your OS audio utility app. Then you need to combine the hardware audio interface you use + the virtual audio interface into one virtual device called an aggregate device. Soundflower, Virtual Audio Cable, and Jack are examples of virtual audio interface apps. This is done using an app that acts like a virtual audio interface and lets you route audio between apps. You need to connect the streaming app to Reaper. So the actual question is probably: Can I make my interface output Reapers audio to my Windows, or do I have to resort to Asio4All and Virtual Audio Cables to create a new recording device? I assume that those L/R outputs are supposed to be the Line outputs on the back of the interface, as well as the virtual Line Recording device I can find in my Sound settings inside Windows.Įvery time I want to use the Line recording device I only ever get the clean signal straight from the Input of my interface, bypassing Reaper completely. Using headphone monitoring and setting the mix knob to DAW I obviously hear the master audio which is routed to the L/R outputs in the device tab inside Reapers settings. Input 1(L) is a mic, Input 2(R) is a guitar. I'm trying to use Reaper for streaming using the ASIO driver of my interface.Īll I'm trying to achieve is that Audio from my XLR mic is treated by FX in Reaper and then routed to an audio device that I can use in Streamlabs OBS for instance.
