(Need feedback) WIP Auto Phase Optimizer / Shifter

So I am working on something that I call a "phase optimizer".

The general idea of this plugin is that is uses some allpass filtering and phase shifting to reduce the amount of headroom that the sound uses.
Similar to Edison's "lossy normalize" function but sort-of realtime.

I thought "what if I can phase shift and optimize sounds so I can make them louder? Make 808s hit harder?".

It is not perfect, it has artifacts and I'm still trying to figure out how to improve it, maybe I have to do multi-band processing for better results.
I was hoping people might be able to help me out here.

So how does it currently work?

- Just load this onto any track / channel that has a sound playing, that's all you need to do.

- I have sound A and sound B.

- Sound A is raw, sound B is allpassed / phase shifted.

- If B has less decibels than A, crossfade into B.

- If B does not have less Db than A, do nothing or crossfade back to A.

- A delay of about 10ms or 20ms is used before the crossfade so it crossfades right into the phase-shifted part of the audio, otherwise the crossfade happens too late and the optimized part gets missed.

- Multiple passes with different cutoff allpass filters are used to find more potential phase shifts that might work.

Why did I make this?

I'm not a huge fan of using side-chaining or EQ slotting as standard solution for everything, it often just doesn't work very well for dynamic and complex soundtracks and music where instruments and notes will be all over the place and constantly shifting around in the frequency spectrum.

I'm no sound expert but I was hoping that optimizing phases would somehow make mixing easier.
I'm generally also a bit obsessed with automation and finding ways to make a 808 or a kick hit as hard as possible without resorting to extreme clipping or distortion.

You'll probably still have to mix your sound even if you do optimize the phases, it doesn't prevent phase cancellation, as far as I know it just allows you to get a little extra volume out of a sound before you hit a limiter.

I want to improve it and make it an actual useful plugin.

I've seen a cool VTS plugin that optimizes phases in realtime but it costs like over 200 dollars and I wish FL Studio had more built-in tools for phase manipulation.
I think the plugin was called "Pi Phase interaction Mixer" by Sound Radix.

Tinker around with it, let me know what you think of it, feel free to edit or make adjustments to the patch.
I want to turn this into something cool and free to use for everyone.

Reminds me in some ways aspects of my Patch BTP...
