I'm a user of Reaper and OBS, but nevertheless it seems I cannot find a good solution for my problem:
We have a conference room with 3 microphones that go into an AKG mixer & audio interface. In Windows, I see one input-device which is the mixdown of the microphones. Unfortunately, the signal from the microphones has an impressive noise floor and it could also use some eq adjustments. All this can easily be done with a noise-gate and some simple filters.
Question: Is there an easy program that can sit between the pure mic input and act as a man in the middle to adjust the signal that goes to Hangouts, Skype, or Discord?
When I understood this correctly, then I need e.g. a VST host which creates a virtual device as its output that I can then select as "microphone" in the application. I've seen that I can do this with DAW applications but one requirement is that it will be easy to fire up once all filters are set up. This is necessary because it basically needs to be started by anyone who wants to make a conference call.
I can provide further information if necessary.
