Audio volume envelope

I created the audio “Normalize 1 Pass” filter just for this purpose.

There is some context in these threads:

Introducing the One Pass Normalize Filter and Audio Loudness Scope

The previous audio normalize filter has been renamed to “Normalize: 2 Pass”. Its functionality has not changed. You can select a clip, analyze loudness of the clip and then the filter will apply a fixed gain “shift” to achieve the target loudness across the clip. The target loudness is configurable. This type of normalization is most appropriate for pre-mixed clips like music or clips where the volume is constant for the duration of the clip. A new audio normalize filter has been added named “N…

Having Trouble with Normalize

Hi! I have a single video track, which includes audio from 4 different mics (a Skype group call). One speaker is louder than the others, so I’d like to reduce his volume. Normalize seems like the way to go, but I can’t seem to get it to work. If I click on the ‘clip’ and add the Normalize: Two Pass filter, I get the Target Loudness toggle and am able to set it to any value I want. But after clicking Analyze and letting the job finish, I hear no difference in the audio. I set it to -23, but the…

Audio normalisation in LUFS

I would like to set up some output presets which, in addition to outputting video with the selected codec parameters, normalise the audio output to the correct level for various streaming services to minimise the dynamic range compression/volume adjustment they apply. Would it be possible to use an LUFS-based audio-normalisation library (such as libebur128 in FFmpeg) to normalise to a given target value? If so, how?

Also, here is a video where I describe how I use track filters to normalize audio and overlay the file date for my home movies:
