The attached pic shows a soundtrack where I have lowered the volume in the middle with a keyframe.
There’s a left linear scale panel that ranges from 1,0, 0.5, 0.0, -05, and -1.0
As you can see in the pic below, my guess is that when the volume is higher, the value must be about 0.8 and it’s lower, it must be about 0.3 - see pic for clarification.
Is there a way to know the exact values so that I can replicate it in another similar project?
You can, but you’ll get a sudden jump up or down in volume and that will probably sound bad… And if the audio is different they may not sound equally loud because perceived loudness doesn’t correlate well with the peak levels…
- Select the part of the reference file that you want to match.
- Run the Amplify effect and make a note of the default amplification, then cancel the effect without applying it.
The default amplification indirectly gives you the “headroom”. For example, if it defaults to +3dB, your peaks are currently -3dB.
- Now select the audio you want to change. Run Amplify again, enter the desired new peak amplitude, and apply.
I’d recommend using the [u]Envelope Tool[/u] so you can fade-up and fade-down the volume with no sudden changes. But this will not be “exact”. (The Envelope icon has changed and it doesn’t match the user manual but it’s still in the same place.)
Ok thanks, I’ll try that.
OOH thanks for that “nudge” Doug - I’ve fixed that in the alpha Manual for the next release.
Over time the Manual as it is is likely to disappear as Muse are preparing to replace it with their support GitBook:

But for now I still try to keep the old Manual as up to date as I can manage.
