Everything From Spaces I And More

The original Spaces was lauded for offering a plethora of reverb options, from creative to highly surgical. By adding Spaces II to your mixes, you get hundreds more reverbs recorded in churches, concert halls, opera houses, catacombs, train stations, recording studios, and warehouses. The new streamlined UI and control features enable you to access every reverb and make edits rapidly, with minimal delay between searching for the most suitable reverb and finalizing your settings. And because it includes all reverbs from Spaces I, Spaces II is the most powerful and versatile convolution reverb on the market.

Introducing Spaces 2.5

Spaces 2 now includes brand new features and support for VST 3 plugins and M1 / M2 Apple Silicon. If you already have Spaces 2 or a ComposerCloud subscription, you can update to Spaces 2.5 now via our Installation Center.

Spaces 2 now includes brand new features and support for VST 3 plugins and M1 / M2 Apple Silicon.

Send Mono Control added to enable a mono signal to be sent into a stereo impulse response (IR) in order to recreate the spatial characteristics of a given space.

Use stereo width control to enable the option of widening the image of stereo and true stereo presets.

Updated filter page now features a sonogram display that combines equalization and response into a single visual readout.

Updated envelope page allows the selection of a Simple Mode with a single decay control, or a Full Mode with a multi-node envelope that enables control over the attack and decay stages of the impulse.

From a large orchestra down to or a 5-piece ensemble or solo performance, Spaces II makes it easy to select a contextually appropriate and believable reverb for nearly any stage or environment you like, while offering clear detail that would normally get washed away in other convolution reverbs.

Concert Hall

Brand-New Spaces

From stunning concert venues like Abravanel Hall in Salt Lake City, Reynolds Hall in Las Vegas, and the War Memorial Opera House in San Francisco, to exquisite sounding churches like St. Patrick’s and St. Dominic’s, to unique and extraordinary sounding locations like catacombs and Union Station in Los Angeles and many more, the reverbs from these brand-new spaces will inspire you and help bring your compositions to life with incredible realism. These are some of the best locations EastWest has recorded in and they will all perfectly compliment the locations from SPACES I.

Concert Hall


(Churches, Concert Halls, Opera House)

The ideal choice for choirs and orchestras, these reverbs have a long tail and present a lot of detail. With so many to choose from, you’re certain to find one with the exact density and tail you’re looking for.

Dark Forrest


(Caves, Courtyard, Forests)

Perfect for sound designers who need to recreate a physical space with strikingly different acoustics from anything you’d normally find in a reverb collection. Excellent for open spaces and unconventional settings.

Empty Warehouse

Large Indoor

(The Catacombs, Parking Garages, Swimming Hall, Train Stations, Warehouses)

Sound designers will find these reverbs valuable for foley work and adding to ambiences, and composers will love the opportunity to place their musicians in an environment far removed from a typical performance hall. The incredibly long tails in this collection are unlike any other spaces you have at your disposal.

Recording Studio


(Plates, Rock Rooms, Studios)

If you’re writing classic rock or want to emulate a session recording, these reverbs are the way to do it. We captured the impulse responses of a plethora of classic plates and studios perfect for creating just the right amount of ambience--not too much, but you would miss it if taken out of the mix.



(Digital, Tanks)

A sound designer’s paradise: this is an excellent way to force your sounds through unrealistic and eerie metals and digital environments and heavily morph the final result. The result can be a bit unpredictable--but sometimes it pays to take a chance.

Grand Piano


(Instrument Specific Tour, Solo Vocal)

A collection of reverbs tailored specially to some of the most common instruments available, including pianos, strings, vocals, and synths. When you want a quick way to create the perfect ambience for a specific instrument, try looking here first!

Concert Hall

EastWest’s SPACES I has been my go to reverb for many years but SPACES II is a must for everyone, it’s the most comprehensive and best sounding convolution reverb on the market by far.

Same Revolutionary Recording Techniques

The same revolutionary impulse recording techniques that made SPACES I so popular have been replicated in this new collection. The best gear from Fairchild, Manley, Meitner, Neumann, Neve, Sennheiser, Sony, Telefunken, and TG were used in each recording. ATC Monitors were used in each space to emulate the real-world sound projection properties of various instruments. Spaces II includes a very hi-resolution, True Stereo engine that focuses on delivering the very best sound at a very low CPU load. Most impulses are in 8 channel format, so surround mixes can be created.


SPACES II is a great candidate for being your one and only convolution reverb, offering up plenty of high-quality instrument-dependent presets along with all the essential groups of convolution spaces.

If you have any holes in your collection of impulse responses, Spaces II will obliterate nearly all of them. This level of power and extensive range of options will be difficult to find anywhere else on the market, and regardless of your unique needs, it’s a given that you’ll quickly find a reverb for nearly any physical space you need to replicate.

What’s one space you’ve been desperate to model? Because chances are, you’ll find it in Spaces II.

    Generally, all info related to the reverb selected is displayed in the interface window of SPACES II.

    The following is useful information -

    • M-S: means mono in and stereo out. So normal stereo reverb, where the input is summed to mono before being processed.
    • S-S: means stereo in and stereo out. So true stereo. Each channel L and R is processed with its own unique stereo impulse.

    Typically an impulse is taken with the source on the left side of the stage and the right side of the stage. Each impulse is stereo. When they are put together you get a true stereo 4 channel snapshot of the space. We encourage users to use the true stereo versions of the impulses. The true stereo switch on the interface is an indicator, not a switch. It indicates what you have loaded.

    • FR: means front mics.
    • RR: means rear mics. These can be used to create a surround mix, or to pick a reverb that you like. Generally the rear is longer and darker.
    • FILTER: This allows users to limit the frequencies sent to the reverb, you can high-pass, low-pass, or both. When selected, a frequency response graphic will appear in the center window.
    • DECAY TIME: This allows users to shorten the reverb time of the loaded preset.
    • MONO: turn on to mono the reverb.
