Unevens Curvessor v2.1 WiN Linux [FREE] screenshot
Free | WiN Linux VST VST3 | 13.3 MB
Curvessor is a free and open source VST/VST3 audio plug-in that implements a dynamic range processor in which the response curve of each channel is an automatable spline.

Curvessor can be used as a classic compressor/expander, enjoying the freedom and precision that comes with spline editing.

But more specifically, as it allows the authoring of response curves that are not increasing, Curvessor can be used for creative dynamic range processing in sound design.



Features

The response curves are smoothly automatable splines.
Optional Mid/Side Stereo processing.
The amount of feedback can be smoothly changed, going from pure forward topology to pure feedback topology and everything in between. (NEW in verison 2)
Optional RMS and high-pass filtering on the level detector (NEW in verison 2)
All the parameters, including the knots of the spline, can have different values on the Left channel and on the Right channel - or on the Mid channel and on the Side channel, when in Mid/Side Stero Mode.
Dry-Wet.
Up to 32x Oversampling with either Minimum Phase or Linear Phase Antialiasing.
VU meter showing the difference between the input level and the output level.
Customizable smoothing time, used to avoid zips when automating the knots of the splines, the stereo link percentage, the wet amount, or the input and output gains.

Spline editing

The splines can be edited either by dragging the knots with the mouse, or by entering numeric values for the selected knot.

To enable or disable a knot, double click on it.

When the knots of two different channel are overlapping, the mouse will interact with the control point of the Left/Mid channel.
To interact with the knot of the Right/Side channel, use the right button of your mouse, or press the ALT key while clicking.

To zoom in or out, use the mouse scroll wheel.


Supported Platforms

Curvessor is developed and tested on Windows and Linux (VST and VST3).
If you are willing to build Curvessor from the source code, you may be able to build an AudioUnit/VST/VST3 binary for macOS.

Not just another compressor! I'm gonna have to check it out to wrap my head around this one. It looks like there is actually something new under the sun.

I just noticed the crazy array of everything-ness that this compressor has going on and now, despite not really having the time, I have to give it a run.
I wouldn't have even looked twice but I got stun-locked, amazed that someone brought back a GUI which is clearly partying like it's nineteen ninety nine.

I am Dutch, so much like the youtube guy Wytse ("snake oil") so I just installed it and tried it without manual. I have no f**** idea what it does. After 10 minutes changing knobs and vectors I still did not know/hear what is happening. After that I did read the 3 (!) page manual and I still don't know what it does and how I even would get it to work as a compressor. Maybe I am getting too old for this new stuff.....

I don't know if this will help or hinder, but on the main site, there's a mention of the S-curve under "gammaenv: DSP S-curve envelope signal generator" (which was apparently borrowed from Aleksey Vaneev—the developer of Voxengo—along with R8brain,) which may help understand how it works.
You may have already figured out all of that though, and maybe more than I have so far. Additionally, maybe try and ignore the Mid/Side of it all, as that makes half the controls standard, and some of the others common-er-ish, like the RMS or the feedback, the latter which is more known, e.g., Voxengo's Marquis Compresser or Tokyo Dawn's Kotelnikov. Sometimes it's just how you approach it.

Thanks, I will look into that. It is nice that you think I will be smart enough to understand what it reads!
About Wytse: I am kind amused by his videos. It's for me a rather low level entry in a world of plugins that I do not know of. Maybe it is because I am Dutch as well and are we Dutchies a bit....ahhmm....well....aahhmmm.....a bit-not-so-smart....

It's not a race, take it slow, create noises, drop them into your DAW, contort them by twiddling knobs; with enough fiddling, I find things sometimes suddenly click for me, maybe it'll be the same with you.
I'm just gonna sit back and wait for someone else who's Dutch to come along and be like "This man is not representative of the rest if us!!"

So sorry to disappoint you. We are all like this. The only difference is that some of us do not have ADHD. They only have ADD......
