Virtual Microphone Mix Minus routing

Hello,

I'm trying to understand how audio is routed to the virtual microphone...

In my setup, I am doing a live streamed presentation, with 2 remote guests, with some slides, and video clips. (I am not on screen, just providing tech support for them)

I'm hosting the Zoom meeting, and I use the Virtual Camera and Microphone to provide a final monitor of the stream.

I need to make sure that my guests are not getting their audio fed back in through Virtual Microphone, but only the audio from the video clips. So theoretically I'd have to generate a Mix Minus and feed it to to Zoom via the Virtual Microphone.

The setup works great as is, and my guests only hear the video clips audio. But I don't think I have setup anything special to achieve this. So I'd like to understand how the Virtual Microphone is only picking up my content audio and not the live source audio. Is there a way to select which audio source is routed to the Virtual Mic?

I'm using Loopback to get only the audio from Zoom to Wirecast.

Here are some details about my setup:

Mac OS 10.14.6

Zoom 4.6.12 (Should I be carefull NOT to update that?)

Wirecast 13.1.2

Thank you!

     Wirecast Live Broadcast Area audio feeds the Virtual Mic. It's the output mix, not a separate monitor mix.

    You may want to use third-party audio routing utilities such as Loopback or Dante Via to route a Wirecast monitor mix to Zoom. Wirecast does support mix minus for a monitor mix but that isn't sent to Virtual Mic. That might be a good Feature Request

    In Zoom 5.0.2 I still see Virtual Mic input, just not Virtual Camera (which I believe Zoom says they'll return in an update before the end of May (this month).

     Hello Craig,

    And thank you for this answer!
    Having the ability to send the monitor mix to the virtual mic would be a great improvement! I'll make sure to submit a feature request.

    In the meantime, I think I've worked out a pretty nice workaround with Loopback. Here are the details, if that helps anybody.
     

    - Zoom's audio is fed to Wirecast through a virtual loopback device.

     - I'm monitoring every sources in Wirecast (music, video clips etc.) EXCEPT the Zoom audio input:

    - Wirecast's monitor output is sent to another virtual device (via the Loopback Pass-Thru input). I've also thrown my internal mic in this virtual device, to use it as a talkback mic. I am using this virtual device as my audio input in Zoom.

    This achieves what I need:

    - My guests are getting the monitor output of wirecast (a mix minus, every sources BUT their own zoom audio)

    - I'm always monitoring to the Zoom conversation (via Loopback's monitor), even when Zoom is not live on screen. And I'm also monitoring the mix minus (again Loopback's monitor) to hear the clips/pre-recorded content.

    - The stream output is getting all audio sources.

    Here are some screenshots of the setup:

    Loopback picks up Zoom audio and monitors it.

     

     

    Zoom audio in Wirecast, Monitor is OFF.

     

     I created another virtual audio device, to pick up Wirecast's monitor out, and my mic if needed.

     

    Wirecast's monitor out is ON, and routed to the virtual Mix Minus audio device.

     

     I'm using this virtual Wirecast Mix Minus device in Zoom.

    I hope this helps some people, as it took me a bit of time to wrap my head around this routing. Loopback can be confusing (but so powerful and neat, I love it!), and being new to streaming, I didn't realize the Audio Interface option in Wirecast's mixer is in fact the Monitor out. (while the main audio outs are defined by your Output settings, streaming server, record to disk etc...)

    What would be even better, is multiple virtual mic devices, and the ability to route a "track" in Wirecast to one or more virtual devices. This has been requested before, however there has been no feedback as to when or if this would be available which is disappointing considering this is available in competing products.

    I assume this is the same reason I can't send any audio via Virtual Camera to Skype ? Vision is fine, just no audio.

    Hello Paul,

    You should be able to send your main audio out to Skype still... Have you checked the virtual mic option in Wirecast's Output > Virtual Camera menu?

    Clem, I completely overlooked it at the bottom of the menu ! Thanks :)

    Wondering if anyone else here could help answer some of my Wirecast questions:

  • @Clem - We have  a similar workflow and struggle, so thank you for the Mix Minus solution. One quick question I have is how is the Zoom Monitor Capture INTO Wirecast being accomplished? And what are you capturing - Gallery View, Speaker View or other?

    Hello David,

    Happy to help!

    You mean the Zoom video right?

    It's a Screen Capture layer. in its options, you can either select a specific window or a full monitor to capture. (remember to uncheck Show Cursor and Capture System audio, if you're already picking up Zoom's audio via Loopback)

    I've been trying both, and found that I prefer the monitor option. (The window capture wasn't always showing me the zoom meeting window, and I think it's nicer to keep Zoom full screen on an external monitor and work from this.)

    I've been using the gallery view, and cropping my shots from there, but I guess you could use speaker view if that works better for your project.

    Here's a video from the Wirecast team going trough this process:

  • Hello everyone,

     

    I'm experiencing a problem and trying to make sense out of this. I'm a total beginner in Wirecast and in audio mixing, so I'm struggling a little. 

     

    My workflow is much simpler. In Wirecast:
    - Video capture devices: Webcam and iPad screen -> Virtual camera
    - Audio capture devices: Microphone and iPad audio -> Virtual microphone

     

    In Microsoft Teams settings:
    - Camera: Virtual camera
    - Microphone: Virtual microphone
    - Speakers: Earphones (Yeti Stereo Microphone has a headphone jack)

     

     

    Audio monitoring is OFF for Yeti Stereo Microphone (Layer 2). Audio monitoring is ON for the iPad audio (Layer 3).

    Audio properties are muted for all iPad screen captures in Layer 1.

     

    For some reason, after some time in a call (about 40 minutes), people complain about my voice stuttering, cutting out.

     It's not at all clear that Virtual Microphone, the subject of this thread, is related.
    It's possible that using USB Mic and Monitoring through the Mic might be the issue but there's no way to know. Try monitoring through speaker/headphone jack on the computer instead of USB and see if that has an impact.

    I realize that this is an older ticket but I am trying to find a solution to being able to rout specific audio track(s) to the virtual mic out. Is this feature now available? I have routed audio out to the multiview but really need 2 specific track outputs - 1) to multiview and 2) to Zoom.

    You might get away with Dante Via or VAC

  • You could also try using Secondary Display Out as an alternative to virtual camera/mic. This video explains it: https://vimeo.com/540425073. The video is a bit old though and doesn't include the fact that we added Audio Track support to Secondary Display live output. So you should be able to choose which track you want out to your capture card via Secondary Display.

    I am already using that feature for a different out. I am, when needed, assigning and selecting specific tracks for a different audio feed out with the secondary display. Ideally we could assign a specific track, like you can now do with the secondary display out, to both the secondary feed and the virtual mic.

    Thank you,
    Bryan
