MStereoGenerator: the shortest reverb for transparent stereo width

I am obsessed with short reverbs. But in my quest to find the shortest reverb ever, I stumbled upon a little monster called MStereoGenerator.

And wow… this thing comes in handy so often.

What makes it different

Unlike the classic short reverbs you probably use, MStereoGenerator tries to simulate a micro room.

I mean super tiny: we are talking under 100-200 ms of length.

That tiny space creates just enough reflection to give width, but not enough to feel like a standard reverb.

At low dB levels, this plugin lets me create stereo expansion in a really transparent way. Not as obvious or “reverby” as traditional verbs.

I sometimes use it, yes, even in stem mastering, to add a bit more dimension without introducing obvious reflections.

Pro tip (very important)

Here is the part you must pay attention to.

Tiny reflections like these can easily create comb filtering, especially in the highs. Also, the plugin can sometimes add extra low end or sub information that becomes muddy and out of control.

So here is your safety move: cut everything below 100 Hz.

This keeps the stereo effect clean and avoids that low end “ball of mud”.

Then find the right Character % so it adds width without introducing obvious phase issues.
