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

Classic Echo Chambers Designed by Les Paul

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

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

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

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.

Deeper Still

Deeper Still

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.

Atmosphere, Puts you in a place.

There is nothing really more to say than this just puts you in a place. It is so 3D and helps put vocal's, guitar's, keys.. etc.. all in a similar space in the mix. It's kind of just one of those things that you gotta hear to understand. Un real.

“Legendary”

What a great chamber reverb! The first preset is my favorite; The Great Al Schmitt preset. It adds depth and richness yet hides nicely in the mix. I love this plug!!

Lush! One of UA's best plugins.

I really love this plugin, and use it as much as I can possibly get away with. In an ideal world it wouldn't take up so much DSP (I'm running a more or less brand new Mac Pro laptop, just before they updated to their own chip, and it's noticeable), but it's understandable that it does. Also because of the delay in hearing what it sounds like after you tweak something, it makes it sort of impossible to adjust on the fly, but it's still a lot easier than having to go down into the basement and move mics around ;)

Great but!

Would love a slightly smaller version to be able to run with a 1073 and capitol rooms on an arrow. otherwise great for a bus post record. minus one star for the lack of workable version with preamp on arrow.

A Thing of Beauty

Words cannot do justice to this *beautiful* technological achievement. But "rich", "dimensional" and "otherworldly" scratch the surface.

Impressive! But at $349, Pricey!

I like the way this plug-in modulates higher frequencies, particularly the percussion in Techno, Deep Tech, Progressive and Melodic House digital WAV/_AIFF- files-, but I haven't figured out how to balance low and mid range frequencies which lose clarity and sound muddy. _-_A 14-day demo isn't long enough. I thought it was offered at $175 and I would have purchased that already, but -$349 doesn'-t fit my budget- just to find out that it is another p-lugin I wo-n'-t use aga-in. It co-mes very close.-

Bad Reverb for Classical strings Recording

This Reverb works great for Voice and guitar however it sounds very unnatural when using for classical music strings such as violin and cello.
If you are a pop singer you'll love it if you are trying this for strings never ever get this reverb.

Often brilliant!

Doesn’t work for everything but when it does work, it’s as good as it gets.
