EBU-128 or other audio normalization methods

Is there any opcode or other avenue to normalize audio tracks, or get normalization data? Is there an implementation of EBU-128?
I have a lot of videos and the audio peaks and ranges are sometimes very different. I can watch one video and adjust volume controls, move to another video and get my eardrums pounded.
I’d like to examine the audio characteristics of my videos and make needed adjustments on a batch scale.

Thanks.
