EBU R128 normalisation plugin?

[unfa]

I'm looking for a plugin to perform realtime signal loudness normalisations to comply with EBU R128 recommendation. I'm not looking for a meter, but loudness processor.

Is there an LV2 plugin that can do this?

[tramp]

As far I know, no.

There is a meter to measure it in the meters.lv2 plugins. Doesn't actually change the loudness, just measures it. Doesn't normalization require the entire waveform though? That sort of process doesn't lend well to real-time plugin form.

Yes, to comply with EBU R128, you'll need to measure the whole audio segment and then normalize.
So, while there's no plug-in that does the normalization step for you, it's trivial to do by hand.

Also, if you're working in a DAW, you'd apply the "normalization" as a correction on the master fader, not on a single region, so I can't see how a plug-in that does it for you could be useful.
On the other hand, if you want to normalize a single finished file, you can write a script that reads the measure from the standalone "ebur128" command line utility (http://kokkinizita.linuxaudio.org/linuxaudio/index.html) and feeds it to sox or ffmpeg or ecasound to apply the volume correction.
