I think you would like the loudnorm filter that incorporates ebur-128 adjustments.
It can run as two pass or one pass (useful for live streaming) and adjusts the audio levels to maintain the specified levels.
An example would be -af loudnorm=I=-23:TP=-1.0:LRA=11
This sets the average loudness at -23LUFS (this is pretty standard for UK TV) the True Peak value as -1.0dBfs and the loudness range shows the distribution of loudness throughout the programme.

LUFS is great because it is based on perceptual loudness and not just sample values.

Have fun
