A startling recreation of the world's finest echo chambers.
Located below the iconic Capitol Tower in Los Angeles, Capitol Studios is arguably the most recognized studio in the world — and much of its legend can be traced to its hallowed, subterranean echo chambers. From Ray Charles to Frank Sinatra, Beck to Muse, these underground spaces continue to provide gorgeous hi-fi ambience that is simply unmatched.
Now, after years of R&D and close collaboration with Capitol Studios — including unprecedented access to four legendary echo chambers 30-feet beneath the studio — Universal Audio proudly presents the Capitol Chambers plug-in, a startling end-to-end recreation of the most popular echo chambers ever created, exclusively for UAD hardware and UA Audio Interfaces.
Now You Can:
Record and mix with the world's only authentic plug-in emulation of Capitol Studios' prized underground echo chambers
Add the unmistakably dense, natural reverberation to vocals or drums — far beyond plate, digital, or simple convolution reverb
Create new sounds by repositioning Capitol Chambers' microphones using UA's Dynamic Room Modeling
Audition current and historical chamber configurations, plus new setups curated by Capitol's Steve Genewick
Harness the chamber's entire signal chain including amplifiers, speakers, custom preamps, and mics
Quickly pull up presets from legendary Grammy-winning engineers Al Schmitt (Ray Charles, Steely Dan), Darrell Thorp (Beck, Radiohead), Frank Filipetti (Madonna, Paul McCartney) and more
Take a Listen
Classic Echo Chambers Designed by Les Paul
Prized for their natural sound and dense ambience, acoustic echo chambers became a creative tool for pioneering, forward-thinking engineers by the mid 1940s — most notably UA founder Bill Putnam Sr. and the great Les Paul, the genius behind the Capitol chambers designs. Built from reinforced concrete and tuned using sloped ceilings and a trapezoidal shape, Paul's designs deliver a smooth, balanced decay and a completely natural room tone that can't be achieved in any other way.
Capturing Iconic Echo
In creating this amazing plug-in, UA sourced historic technical diagrams from the early '60s to precisely recreate microphone/speaker setups inside of Capitol's most coveted chambers, including the vintage omnidirectional Altec 21D mics and custom speaker/horn configurations, in their original hit-making positions. Current "modern" configurations dating from the late '80s were also captured, using the omnidirectional Shure SM80s, while new and creative mic/speaker combos were devised by Capitol's resident chamber expert, Steve Genewick.
Unprecedented Ambience Control
Capitol Chambers' Position slider gives you next-level control over spatial and time response, allowing you to reposition the chamber mics — no assistant engineer required. From the maximum distance stock positions, to direct speaker-to-microphone effects and proximity characteristics, the Capitol Chambers plug-in can subtly thicken vocals or drums, or soak strings with the most natural, complex sounding reverb ever recorded.
Powered by UA's Dynamic Room Modeling
Harnessing the same technology as the award-winning Ocean Way Studios plug-in, Capitol Chambers uses UA’s proprietary Dynamic Room Modeling technology, an exclusive combination of physical modeling and advanced measurement techniques. Whereas standard convolution reverbs only provide a sonic snapshot, Dynamic Room Modeling gives the Capitol Chambers plug-in nearly infinite ambient possibilities.
Beyond a vintage recreation, the Capitol Chambers plug-in offers creative features for modern DAW workflows like Pre Delay, Dry/Wet mix, and Decay controls. A sweepable 80 to 750 Hz filter lets you minimize muddy bass going into the chamber, while Bass, Treble, and proportional Q Mid band lets you perfectly season the chamber's lush ambience. In addition, the Width control allows you to narrow the chamber's stereo field, for easily pinpointing a vocal or instrument in the mix. Finally, Decay lets you quickly shorten Capitol Chambers' natural reverb time, offering more scenarios to harness the most famous echo chambers ever made.
An All-Star Collection of Artist Presets
The Capitol Chamber's plug-in features carefully crafted presets from a stunning roster of Grammy-winning engineers and producers. From recording industry icon Al Schmitt (Ray Charles, Steely Dan) to Mark Linett (The Beach Boys, Los Lobos) and Frank Filipetti (Madonna, Paul McCartney), Darrell Thorp (Beck, Radiohead), and more, you can experiment using the same settings that professionals who know every nook and cranny of Capitol's famous chambers use every day.Capitol and the Capitol logos are trademarks of Capitol Records, LLC, registered in the United States, European Union, and other jurisdictions, and are used under license.

Be inspired WHILE you record...
Very heavy on DSP so I'd suggest trying the 14 day trial first, but this thing sounds absolutely gorgeous.
Nobly ages any sound, I use it in every project
My Brand New World
It is a blend of flavours. Sweet and sour! Dark and bright! It can be anything I want a verb to be. It is the part of my template in Luna and Logic. Capitol Chambers takes me back to the future and back again.
Just listen to the demo, this Reverb gives you everything, from a lovely lush to a color that sounds like an amazing record, a fantastic plugin, nothing like it in the market!
Awesome natural sounding reverb, I loved it.
That is the Reverb that we all want this is just magic...
A Must-have plug-in.
So Easy to make reverb sound good!
As much as I love various other UAD reverbs for their distinct characters and textures to create a proper "studio" sound, this one adds a tremendous amount of natural-sounding depth that allows the entire mix to breathe. It's quite remarkable! Also great to bring synthetic sounds and synths to life alongside microphone recordings, especially using closer settings. Capitol Chambers is a powerful tool and a joy to work with!
Just amazing sound
i was searching for a reverb for a ballad style electric guitar. It was by far the best plug-in for that purpose, compared to other plugin manufacturers.
It’s a great sounding natural reverb! You can also go a bit over the top with it and it still doesn’t sound invasive. Good setting choices. Was on my wishlist for a long time…
Unfortunately very CPU hungry. The original price is a bit “juicy” but with all the holiday discounts and coupons it became more affordable so I bought it. Great buy!
This is is the best reverb I ever tried on my electric guitars
Really easy to use and sweet to my ears
Wonderful. Only thing that i have to do is figure out how settings chould be for my satellit firewire unit. It says audio overload in a very small project
Very warm natural space!
