Quite a heavy-handed solution but might be useful just to look at code -
I keep meaning to rewrite this but never have the time.

https://github.com/JamesHarrison/iris

Specifically there's a little Ruby class to talk to the libebur128
loudness scanner
(https://github.com/JamesHarrison/iris/blob/master/lib/r128.rb) and some
code that handles mild compression, gain adjustment etc in here:
https://github.com/JamesHarrison/iris/blob/master/app/jobs/normalize_job.rb

That'll actually edit files to adjust gain since it's designed to be
playout system agnostic. But might be of some use to you.

Cheers,
James Harrison
