I'd like to submit a small request, which promises to be fairly simple.

I've posted it as an issue in the Github repo as well:
https://github.com/reaper-oss/sws/issues/1046

Netflix of all places just changed its requirements. We now need to use the pure 1770.1 version of the loudness measurement standard for their stuff.

There are other tools to do this, but everything is slower than Reaper, where I normalize the items of the 5.1 or 2.0 mixes and do the split-to-mono playouts that I need to pack up and send off. With other tools there's at least one more inbetween step, as none of them seem to be able to generate single-channel files. Thus, I'd rather use Reaper, even if I need to get another tool in the meantime. It's just the better tool.

The Loudness portion of the extension uses the BS-1770.3 or 4 method of measuring as well as the EBU R128 recommendation.

-edit-

It's a little more complicated than just the 1770-1 mode (loudness measurement with no relative and absolute gate)

The whole thing is based on this article which links to the actual recommendations:
https://www.pro-tools-expert.com/hom...delivery-specs

Basically it's a dialogue gate whose output is scanned by the ITU 1770-1 method. We're using the pure 1770-3 method irrc, or perhaps even 1770.4.

The code for the Dolby dialogue gate is completely free. It's available on request via this link : https://www.dolby.com/us/en/technolo...ence-code.aspx

Reaper's extension architecture just lends itself so well to offline scanning, that I'm hoping there's a programmer with a spare few hours to slot in an extra mode in to the existing Loudness portion of the SWS extension.

I've got no C++ IDE experience at all, or I'd try to do this.
