Item one. This is incredible free software. I supervise a Vantage system (and before that FlipFactory) and this is an amazingly powerful tool. It does a great many things either of those commercial products do, and some things they don't, for free. Amazing, and thank you.

Sorry to resurrect this long dead thread. I have been pulling my hair out trying to implement this. I have the same issue as @rholm. I've gone a bit farther and installed ruby on my test machine and built a command-executor block that calls this script https://gist.github.com/kylophone/84ba0 ... a956bf6d54. It works...sort of. It can't deal with spaces in filenames, this appears to be an issue with the loudness.rb script. I have no Ruby experience so I can't fix that. I can probably build some more blocks to deal with spaces, and I'll need to build a second custom ffmpeg block to take the output of the loudness.rb script and add another watch/transcode to get it to the final audio format I need. Not very pretty.

Am I missing a built in function in FFAStrans that would accomplish this without using the ruby script? I didn't see a way to read variables from a text file which was my initial hope. If this is the only way to accomplish this then add my name to the loudness control feature request.

Again, amazing software.

Wow, that's great news. I don't know if it will help but this http://bs1770gain.sourceforge.net/ utility works very well for testing EBU compliance. I ran the EBU test set https://tech.ebu.ch/publications/ebu_loudness_test_set through it and it is within spec on all their files.

Hi Steipal,

Please suggest if you have implemented loudness correction?

Thanks
