Choose what sound each NDI source carries

Give every NDI screen its own audio mix, so the stream gets the sound it needs and the room stays quiet.

Each screen you publish over NDI is its own source with its own sound. The Audio router lets you decide exactly what goes into each one.

Turn on NDI and embed audio

Open Settings, then Network & Streaming.
Under NDI Screen Sources, enable only the screens you want to publish. Disabled screens are left out.
Turn on Embed screen audio so each source carries sound.

Every NDI source is its own mix, clocked by its own screen, so each one carries its own sound in sync.

In the Audio router, find the NDI source row for the screen.
Choose + Input to add the inputs you want in that mix.
Set the level of each input into that source, and the Master level for the screen.
Use the mute button on a row to silence a source.

The hidden copy of each screen stays silent in the room, so the stream mix never doubles up in the sanctuary.

Set a Source name prefix. Each screen name is added to it automatically, so every source has a unique name in OBS, vMix or your switcher.

The frame-rate setting applies to NDI and Direct Live output together.
