It's a least worth a gander, but I'm concerned that it would eat up too much GPU for the rest of vMix to run well.

You have to draw the line somewhere, and unfortunately people tend to think everything offered means everything can be run simultaneously. I could see someone trying this in 4K while running instant replay, and expressing misdirected frustration when it all comes crashing down.

I received a mail regarding SDK availability about an hour ago.

I ran the Broadcast App noise cancelling for the first time tonight. Except for one well-formed chair squeak, it filtered out noise like a champ. Apologies to those who enjoy hearing needy cats.

One interesting thing to note is that ASIO isn't supported. I had to feed the traditional UMC404HD 1-2 input into the program. Everything else was smooth sailing though.

I have an nVidia GTX-2060 graphics card. Are these features available with that card and if yes, how do you enable them in vMix? I'm hoping to reduce room noise, etc. from multiple mics I'm bringing into vMix via a Behringer 404 UMCHD audio interface (up to 6 Rode Wireless Go II mics). Thank you.

To enable nVidia Broadcast in your vMix workflow, try the following:

For video effects
1. Expose your vMix A/V source as NDI (in my case, I am using it with vMix call)
2. Use Webcam Input from NDI tools to convert NDI to virtual webcam (vMix external is not detected by NVIDIA Broadcast)
3. Open NVIDIA Broadcast and select "Newtek NDI Video" as your camera source
4. Add effects (background replacement, Auto frame etc.)
5. in vMix, add Camera input and select NVIDIA Broadcast

For audio effects using Newtek NDI Audio produces jittery results. I found the following workaround;
1. Install any virtual soundcard driver
2. in vMix settings > Audio Outputs , select your virtual soundcard in any of the busses (lets say A)
3. Send the audio of the input source you want to process to Audio Bus A
4. Select your virtual soundcard in NVIDIA Broadcast Microphone settings
5. Add effects (Noise removal, room echo removal)
6. Same as the video effects step 5 above, you can bundle the NVIDIA broadcast audio along with the video while adding source back into vMix.

Dirty solution but it works.

note : Background removal filter works! Resulting webcam image have an alpha channel. So you don't have to key in vmix.
