This is a pure game changer for independent artist!

I saw the review for this on the UAD channel, so I got the demo to try out on my new Ep I'm working on, this is that "thang". This is really a game changing piece of gear. Put it on your master bus and baby your life will change! Universal Audio does a phenomenal job at creating these plug-ins, this is beyond incredible. As an independent artist, I encourage all of my peers working to get your sound as close to a pro studio sound, to get this plug-in or at least demo it, you can thank me later. You will hear instantly how this thing makes the track bigger, not louder...bigger, warmer, cleaner, fuller and more polished. It's that "Thang."

Finaler Schliff

Seit 5 Jahren bei fast jedem Master oder Mix in Verwendung. Hilfreich um Instrumenten- oder Vocalgruppen Tiefe und Breite zu verleihen. Funktioniert für mich am Besten auf sehr dichten Mischungen.

A Quick Way to Add Ambience

This plugin is very good in that it cleanly provides presence and ambience without adding phase artifacts (at least I can't hear any). It adds an audible 3D sound field to an otherwise flat 2D-sounding image. It's hard to describe, but you can hear it when you put this on your master bus. Highly recommended.

The All-Around Plug-in!

This plug-in provides a depth in the stereo field which is very helpful for me as a vocalist because it helps with sitting vocals right upfront in the middle of the mix. I stumbled on this plug-in by accident and I'm so happy I did. This plug-in is a must have for engineers and producers.

software instruments? fear not...

Adds a lovely sense of depth which helps to make something digital sound like it's been recorded in a room - I like

After hearing you can't go without it

I've had this plug-in sitting on my wish list for the longest time and now I finally purchased. I added it to the stereo bus and tweaked the controls a bit and WOW! It added so much width and balance to the recording. I turned it off to compare without it and was blown away by the difference. I would absolutely recommend adding Precision-K Stereo to your plug-in library.

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.
