Does anyone have a script that demonstrates how I can duck one input based on volume level of another input? I know I can do this with Waves C1 compressor, but I'm hoping there's a script way to do it.

I was hoping to be able to figure this out for myself by reviewing the object reference for the vMix API, but I can't even find that. Can anyone point that out to me?

I watched this video, but unfortunately it doesn't include any information about the script itself. So, the hunt continues.

The full script is in the pinned comment. The comments within the script can be translated with google translate

Is there a way to unconditionally run this script upon loading a given preset? Or, must I start it manually with a shortcut or Stream Deck button?

Assuming you started the preset manually, start it manually with a shortcut or Stream Deck (or other controller) button or open Settings -> scripting -> select script -> start

Can be potentially "dangerous" to autorun a script at preset loading , must be sure the script is completely bug free

Can always make a auto launch external option (bat file or alike) but must be sure all is fully loaded before commanding the script to run

Maybe a feature request ?

I figured as much; an overt act (e.g., shortcut, button, etc.) is necessary to start scripts.

The script is great; it works perfectly and I like the settings for controlling how it behaves. The only thing I'm going to change is the variable names for the two inputs as my use case does not involve a Russian translator. This is turning out to be not as simple as it sounds. Any suggestions?

Hey guys, thx for this amazing script :D

I unfortunately might have found an issue though:

When running the script with the "translator"-input unmuted nothing will happen until I muted and unmuted it again.
This happens every time that I start the script.
But of course, I'd like the ducking to happen as soon as the script has been started.

Any suggestions?

a while ago I posted an example.

Long time not used so no comlaining!!:-)
for example you have a moderator and then a video with sound running.


If now the moderator talks in his mic the video audio decreases
and is increased again when mod stops talking

Code:
do 
Dim xml as string = API.XML() 
Dim x as new system.xml.xmldocument
Dim HSLvl as string = ""
x.load("http://127.0.0.1:8088/api")

HSLvl = x.SelectSingleNode("//input[4]/@meterF1").InnerText

 ' adjust video level corresponding to mod mic level

if HSLvl >= "0.02"
api.function("SetVolumeFade", input:= 'video', value:= "50,500")
sleep(500) 'to have the audio level not jumping around...
else
api.function("SetVolumeFade", input:= 'video', value:= "100,500")

end if

'console.writeline(HSLvl) 'just for debugging and level monitoring

loop

I was able to achieve this with one script that is available on youtube. Here is how it looks in action: https://www.linkedin.com...tm_medium=member_desktop

Greetings! I am the same Kirill Kudryavtsev who wrote the script! Please tell me where the mistake was and what did you write instead? I have already prepared the second version of the script, it is very interesting to know about the incorrect code and its location!
