Yes I forgot to tell. The "rate" and "depth" knobs controls the vibrato speed and depth of the chorus. Its sort of an underlying chorus that you don't hear much, but its responsible for the widening effect.
The "delay" knob adds a constant delay to the wet signal, to further define the character of the widening-effect. Its also useful in cases where the volume of one channel begins to waver above/below the other channel. This happens sometimes on one-note sounds, and is a natural side-effect (so to speak) of the plug-in. But its rarely desirable so if this happens, you can dial the "delay" knob a little to solve the problem. Or use a compressor/limiter after the stereoizer. (Though this will affect mono-compatibility to some degree)

That just about covers it, braindoc. The stereo input is first converted to mono (L + R) then it goes through a mono chorus-effect (pretty much a standard chorus with a triangle wave for vibrato. I tried other waves as well but triangle worked best. Perhaps it would be icing on the cake to smooth the edges of the triangle, though in most situations the difference would probably be inaudible). A constant delay is obtained with the same code and controllable with the delay knob. The signal is then converted to stereo and one channel is inverted. Then its goes to the dry/wet mixer. The mixer is a bit unusual as the ratios are different. The dry signal won't drop below 100% until the slider is below mid-position. Similary, the wet signal won't drop below 100% until the slider is above mid-position. At mid-position, both wet and dry are 100%. This gives you "full effect" while remaining fully mono-compatible at this point.
Sometimes simple works best and I think this is one of those cases. I was surprised that I couldn't find this type of stereoizer elsewhere.

Yes, sometimes there is a noticable flanging. You can rid it, by dialing the depth knob to zero. This might work well for drums. It will disable the chorus though. What you have left is actually a "surrounder" effect, that you can also get elsewhere.

Yeah well, I hope not. I thought "stereoize" was a common enough word, and it seemed like the best way to describe the plug-in...

Perhaps if you could elaborate on this? What would be the purpose of a phase-meter?

I thought about this. Perhaps the numerical values could be shown when hovering the mouse over the knobs and fader. I don't know how but maybe I'll look into it.
