Still trying to understand whether I am doing something wrong. I reported a bug in MUX channel delay on the last beta before release. I can't find it in official 7.71, have tested both 32 and 64 bit in extreme tweaker, so I thought it was suspended due to the bug. Then, I see it in the updated feature list. uninstalled and reinstalled both, still no go.
What is the story?

I am on Mac, there is no .DLL the plugin is a single .vst file. I tried renaming the .vst file but it also didn't showed up in the VST Plug-in list.

Sample-accurate delay in SFN MUX has the potential to work some miracles!

Initial testing was performed today, muffled sound just changed to clear baseband by adding appropriate delay of 34 samples, exactly as initially calculated, with some audible chirping due to idle carrier frequency mismatch by almost 700 Hz. GPS-locking the PLL Exciter's frequency using 10 MHZ GPS reference sources could do the trick. Heck, even aligning crystals properly could enchance the results. I'm on to it! This summer is rather hot - I am sitting in a seaside cafe right now, (temp is 36 deg c). in the center of the affected overlap area and adjusting modulation levels (FM capturing helps!) down to 0,1 dB, when I gain access to the actual transmitters this margin could decrease twofold.

I went to radio station's owner with a mood like "Daddy, Daddy, I want this software, can I have it pleeeeeease???? (he's no dad of mine but we are quite playful when happy!)

Video of the MUX delay per sample enable testing (captured inside a pitch black car (thus HOT!), external temp 37 deg. c, in broad daylight, using a potato that has awful audio). Worth the sweat. I even reversed the channnels in an effort to emulate the worst case of interference, treble went bye-bye when I did.
