We use vMix at our church. The music is usually louder then the speaking portions and when I watch the replay or live stream I find it necessary to adjust the volume on my device when we switch between the two. How do others deal with this?

I'm no expert, but since no one else is answering, I'll take a stab.

Have you tried going to the audio settings for that input, and enabling the Compressor? If that doesn't do what you want, you can add VST audio plugins. Look for an auto gain control VST plugin.

I'll look into those suggestions, thanks.

I'm hoping to make due with the audio guy already mixing for the FOH. I think the issue lies in that as a live venue, we like the music a little louder then speaking and the room allows for that but streaming on a TV doesn't allow for such dynamics.

For the ones who do it all in vMIx:

Crate Two internal AudioBusses (enabled) Decide wich is for Speach and wich is for Music.

Route both busses to the master wich is your stream source.

Now you will need VST3 Plugins i recommend waves Plugins I tested a workflow with waves Plugins and all plugins from waves are availible in vst3.

Install on both busses the “playlist rider” plugin and set them to the same amount oft target value (-18LuFs)
Threshold must be tested to set. Longterm is smoother.

This plugin is setting all audio above the threshold to the given target loudness.

So it it will make Speech and Musik loud the same if selecting same target. But music will still sound bigger because it is a mix and not a single voice.

If you want to overcome this set speech to -14 and install on the masterbus an mastering compressor plugin.
Threshold setting that it only affects the small spikes in music but all ways compresses speech.
Keep in Mind that it is complex to make speech sound as thick as an radio station while youbare in a church with a big reverb.

So you currently have an FOH guy.

He can do what i told on his desk.
If he have an modern digital mixer he can archieve this by doing what i told in his desk.
He can use compressors to archive a similar sound.
The Desk must work with Mix Groups and Matrix Groups to stack the compressors to the mixes and compress voice and band differently. And then sum both mixes on the matrix channel wich you get.

He also should use a Headphone to listen regularly in the Feed he sends you. For decent Stream audio especially in church two consoles are required only sharing inputs.
Alternatively use a big desk wich is good for two person operating.
This enables the stream the Stream Audio Guy to Focus only on the sound for Stream and is not limited to foh sound and avoiding feedback.
