Hi! Does anyone uses any automixing solutions? If so, please advise! Thanks in advance! Some info from wiki, just FYI: Quote:An automixer, or automatic microphone mixer, is a live sound mixing device that automatically reduces the strength of a microphone's audio signal when it is not being used. Automixers lower the hiss, rumble, reverberation and other extraneous noise that occur when several microphones operate simultaneously.
Automixers are typically used to mix panel discussions on television talk shows and at conferences and seminars. They can also be used to mix actors' wireless microphones in theater productions and musicals. Automixers are frequently employed in settings where it is expected that a live sound operator won't be present, such as courtrooms and city council chambers.
Automixer hardware or software uses a variety of methods that allow increased gain before feedback for live sound reinforcement as well as reducing comb filtering between multiple microphones for recorded and broadcast applications.

Scenario I'm talking about: we have few guests close to each other - for instance sitting arround the table. In that case, we will face up situation, when one guest is speaking, other few lavalier mics will catch his sound also and as a consequense - speaking guest will sound with a terrible echo. Automixer will help to get rid of such a "parasite" crosstalk coming from other mics located close to our guest. Of course, if you have sound engineer - he will manage such a stuff. But in case, when there's no such a guy, automixer could help tremendously.

Soo.. what you are looking for is called ducking in the audio engineering world. Pretty sure there exist some plugins for that.

AFAIK there are no software only VST3 plugins for automixing. Stigaards notion on ducking (e.g. by side chain compression) is close, but no cigar. The VST3 plugin https://www.waves.com/plugins/c1-compressor has this feature. We've used it in vMix to duck the venue's microphones (Audio Input from house audio mixer) using incoming vMix Call audio as the side chain source. This to avoid feedback from the Calls audio sent to the PA being picked up by the microphones. But it was very cumbersome and limited by vMix's bus structure. Hence we have switched to automixing by routing audio to an external Behringer XR mixer and using it's built in automixer. While an external mixer in many cases are better/viable I still think that sometimes it would instead be nice to have everything inside vMix. There are (at least) two Feature Requests that if implemented would make ducking easier. Sending Audio & Sidechain Compressionhttps://forums.vmix.com/...ts/t20691-External-Audio

I love when I'm proved being wrong :D
Good catch! Have to try...

WT has a video demonstrating their automixer with vMix:

How is this software gathering the audio from other inputs within vMix ???
That is the big issue!

Steve Just take a look at the video from the post above. You have to use plugin in several audio inputs. All these are somehow gathered inside one VST plugin. Very smart scheme I have to admit

Used it on a Job back in November, On up to 12 simultaneous callers (media looks) it worked very well.
had to keep it's control panel open so individual channels could be bypassed as we found if a caller wasn't using headphones and their speakers were a bit loud we got some of the other callers audio coming back down and triggering the auto mixer

I would be grateful if you would share your findings...

I've also signed on to the below feature request, but if I could just duplicate what you say you've done with C1 it would be helpful to me. I can't see how, within the plugin's configuration, how to designate what audio source I want as the sidechain. I've applied the plugin to two sources, and I can't see where to designate which source I want to sidechain against in C1-SC.

It was really complicated, used a couple of the (scarce) available buses, and also requires a virtual cable. If I remember correctly:
You need for a chosen bus (output to virtual cable's input) select "C1 Comp-sc Stereo" and for A->B have the Call on left channel only (routed via Input's matrix) mikes on right channel only (matrix routed), adjust C1 settings (experiment). Then add the sidechained virtual cable output as an Audio input (now with ducked mikes on "2" in matrix routed to both L and R outs).
We changed strategy and use automixers instead.

We changed strategy and use automixers instead. OK, gotcha. Looking over the manual for C1 I was afraid it was something like that-- I used a plugin in the past (with OBS, not Vmix) that could take 4 channels and use 3/4 as a stereo sidechain... I was afraid looking at the references to L and R channels it was going to be something like that. Looking at the WT Automixer linked here but what I'm looking for I think is a bit different.. I don't want to turn down mics that aren't in use to reduce noise, I have program material that I want to reduce in volume by a certain amount when mics are active, but let them come back up to the level of the mics when the mics are silent. Thanks for the help, though!
