    I've been hearing about it and am quite confused, but very intrigued.

    It looks like you send a track from your DAW into it, and from the outputs of it back into your DAW and it makes it sound all cool. Kinda like Reamping a DI guitar into an amp only instead of an amp it's a dolby unit.

    You know what a dolby SR is I hope?
    In case you didn't know what it is...

    A Dolby SR unite is an encode/decode hardware unit used when analog was king.
    We speak about 2 inch tape here. ;)

    As you probably know, high end part of the frequency spectrum and analog tape don't like each other.

    So the normal use of a Dolby was to put it while recording (preamp>dolby>tape machine). And what this do is boosting high end for compensate for the lost tape give.
    Now when switching to repro (playback if you like), Dolby is on decode mod so you ear what your track sound like without the high end boost.

    So the "trick" is to use a dolby SR unit in encode mod (extra high end boost), but not using it in decode. So when playback you still ear your track with the high end boost.

    But to be honest, don't spend the 400$ a dolby SR unit cost on ebay for that...
    It's not like this will killing your world or something.

    does this plug work with the nebula free? or does it require the full neubla3 pro?

    I don't know, I don't own this program (I plan on buying it very soon but I own Nebula3 Pro).
    The site says it requires Nebula 3 Pro though.
    You can still try the kernel limited demo version with Nebula free and see if it works.

    Nebula 3 Free does not load 3rd party (non-Acustica) libraries, so unfortunately no.

    OT: The Dolby trick seems to add high-end to a signal dynamically, more like a dynamic eq than an exciter IMO

    Exactly, but i think the compression it does is the biggest benefit, it helps vocals pop out in a more pleasant way.
