ffmpeg's "ebur128" filter handles a subset of this, apparently. I'm sure it would appreciate some additional algorithms. Patch welcome. ;-) > 2.

I'm not aware of that option (ffmpeg doesn't even support double-dash options?), but you can use the "volume" audio filter: [...] -af volume="7.3 dB" [...] or something like that. And don't forget to avoid clipping, unless that doesn't matter to you.
