The unHiJacked thread – Level control -Live stream mixing and related

How do you measure your LUFs or similar required levels for streaming to radio, TV, CDNs, yada yada?

Radio & TV have legal requirements to be met.
CDNs have specs that they will do what is necessary to fix your levels to fit, if needed, or in some cases reject your file.

Clearly nobody has calibrated ears that can guarantee that their signal level is proper per legal specs.

For many churches the sound is sent to a PC with OBS or similar to morph with the video and may be further processed.
We can not control what happens there so it seems best to just send them a LUFs spec signal unless they say otherwise and indicate they will readjust after their processing to meet legal requirements or others. Some send direct to radio/tv so should be at correct levels for those. And some people feed multiple destinations and need multiple differing levels to be transmitted onwards.

So if the video PC does not have visible meter then we definitely need one. I would like to have one anyway if just for the live audience that might have SPL levels restricted by local laws.

Seems like the best way is to add a PC with a parallel output from the mixer and use a software LUFs display.
Is there a simpler way a hardware device that could do it?

Or would you just give your video team something ‘reasonable’ and rely on them to fix everything.

I am surprised that the QUs do not have a better level meter with variable integration time instead of just coarse levels and leds and using a very short time that they are valid.

If that’s your problem fix it…
fight for control of the audio part…

you need access to metering after encoding…
or at least metering at the very last step before encoding
OBS has metering already integrated, try to use this
a mirrored OBS display (HDMI splitters cost around $20) would be a possible solution

Seems like the best way is to add a PC with a parallel output from the mixer and use a software LUFs display.

this is the worst idea…
then you have to maintain the configuration of an extra device (gain, connection, what happens if somebody is changing levels in OBS?)

you should add the PC to watch the stream in parallel…
then you see the program and you are able to control what happens in the stream without complicated configuration
and you are able to listen to the broadcasted signal, it’s always a good idea to check what happens at the end…

If your church is not able to provide the needed tools to get the job done well,
then you’re stuck…

LUFS is much overrated for simple streams
make sure your average level is around -15dB FS right before the encoding
