Subtle Magic Dust

Great plugin for carving out a little sonic space in the mid or side of a stereo bus, i.e. guitars. Also, a nice touch to restore a bit of the natural room sound from a drum kit recording. I wouldn't use it on everything, but I've found that both these use cases sound great and are complementary to one another.

“Wider Than Life” mixes

This is an ideal plug-in if you’re looking for a broad, open sounding mix. Just drop it on the stereo master! For songs with vocals, I cut mids from the effect to keep the lead centered.

I've tried this on a one dimensional live-recording (with about 9 vocal-mics panned to the center). The only stereo-information came from a reverb and an electric piano. Inserting this plugin and choosing the preset "Big" instantly gave the mix a smooth, enjoyable width. The vocals were suddenly blending perfectly! Wow.

Precise subtlety is not something companies usually focus on when making a new plugin.
Lots of elegance and musicality in the design of this. a rare kind.
Thanks Bob and UAD

Very good tool!

I use this tool to design the stereo depth and stereo width. A few subtle attitudes already lead to fine results and success. The user interface is very clear and explains itself. The sound results are very good!

Works don’t over saturate the signal

Like all signal processors via hardware or software it depends solely on the goal of the mixing engineer. This has a place in my toolbox.

Must have plugin.

This is a very unique plugin but extremely helpful help enhance ambience. Of course the ambience and room had to already be there. It doesn’t create ambience but enhances what you’ve already recorded so it breathes more life into said recording. Love it!
