Hi,

if you are on IFB (Interruptable Foldback), than is gets tricky with vMix, since there is no N-1/mix minus setup for outgoing audio. Mix minus only works on vMix Call connections.

You have incoming audio and intercom on the same channel, in this case the same bus in vMix. If you record this bus, all audio on this bus is in the recording.

I don't understand your setup completely, since in vMix you can not have two-way communication on the same SRT data pipe (although the SRT protocol should be able to handle that). As far as I understand, there are two sources in the incoming audio (commentator and cameraman) you want to seperate; but they are already mixed into one audio sum signal. A simpe routing can not seperate this anymore.

We did a similar setup for remote production like this:

Connection 1: | Remote Site: | -> Programm Video + Audio -> SRT -> |Studio: | vMix Input -> Video to PGM (Output) / Audio to Master Bus -> Recording

Connection 2: | Studio/vMix: Intercom Mic -> Audio Bus B -> (Signal Output2: Video: Webcam Producer or Studio Signal / Audio Bus B) -> SRT -> |Remote Site|

You would need a third path like Connection 1 für the cameraman feed. Alternatively, get the cameraman on a vMix Call on his phone and handle the proper audio routing to this call in vMix at the studio site.

Let us know what worked, please.

Best,

Christian
