I would vote for LUFS scales with loudness metering and if audio is EBU 128 compilant.
On one HW device i saw changing color of bars according volume...it had 6 bars...6 green was -12dB...and from top started being yellow from top to down...all yellow meant -3dB....and red in same way in scale -3 to 0dB

As a model I would consider Wide Range Peak Meters from Darkwood Designs. I've been using these along with VoiceMeeter Banana and vMix.

With regards to peak and loudness, with digital audio there is no such thing as > 0dB
All audio coming in has a maximum amplitude (loudness) defined by the bitrate (16 bit etc)

This is called dBFS

Determining clipping can be tricky depending on the audio device as the audio source may be clipped
but never reach exactly 0dB, so currently in vMix the square boxes represent 2dB each and if
the audio is greater then -2dB the red box lights up and is held for a short duration to show a peak.

So please consider this when offering suggestions.

For those that are mainly looking for specific dB peak numbers for confidence, how about when the mouse is over
the meters it shows the maximum dB level for the past second or so (and maybe LUFS)?

We really do need the legend and we should really be using a PPM (Peak Program Meters) for broadcasting, you will find that any broadcasting company will be using these meters, the industry standard ones in the UK are the BBC PPM meters. I use Logic Pro x for writing music and I use the Darkwood Digital BBC PPM meters.

Martin take a look at this website: http://www.darkwooddesigns.co.uk/pc2/meters.html

HI !

truepeak metering , opengl based.

But Martin.... if you add vst3 64bit support with automatic latency compensation....
its much better, and everyone can use whatever they like to use....

kind regards,

PFBM

I understand people are asking for legends, but I need suggestions on how they would fit?
I can add them to the audio settings window, however it would double the size of the audio mixers for them to be readable.

VST support!

Hi Martin,

If you don't want to rehash the vMix interface then take a look at the attached pic I have done.

I have left the interface as normal accept for the Quick Play, Cut, etc. buttons, I have made these buttons slightly smaller and pushed them up closer together plus I have removed the audio bars and made the Quick Play, Cut, etc. buttons wider I then moved the transition bar down as to get the new audio bars in place. As you can see I have put the legend bars over the audio bars with the dB numbers in the middle.

I hope this helps.

That space is where the video playback controls are so can't fit there either! ;)

I think I am going to leave the full audio meter in the audio settings window
and have peak information on the mouse over for now.

The meters will also be colour coded at predefined db levels.

Martin,

How about my idea? You say "That space is where the video playback controls are so can't fit there either" In my picture I have left that space alone due to the video playback controls.

I think your idea about having to do a mouse over on the audio meters may be a problem for most people who are only using a mouse to do there switching especially when one person is doing all the switching like using 4 to 6 cameras plus other stuff like using stingers etc. like on a football or ice hockey match, they just wouldn't have the time to be doing a mouse over, we need to be able to do a quick glance at the audio meters to make sure we are not peeking into distortion while switching.

Would it be possible to have the meters floating so we could place them anywhere on the screen or on the desktop? like you have done with the audio mixer.

Just some thoughts and ideas.
