ValhallaRoom features several original reverberation algorithms, designed to produce tight and subtle room sounds, as well as larger hall sounds and huge ambiances.


  • Unique Early reverb section allows user to dial in subtle and short bursts of early reverberation energy, as well as gated reverbs up to 1 second in length.
  • The Late section produces natural reverb decays ranging from 0.1 seconds to 100 seconds. The decay can be controlled in 3 adjustable frequency bands.
  • Both Early and Late reverb sections have adjustable modulation, to produce sounds ranging from lush chorusing, to subtle and natural long decays.
  • ValhallaRoom is true stereo. The Early and Late reverb sections are both stereo-in, stereo-out.
  • Mix lock functionality for the Mix slider. By clicking on the MIX label above the slider, the user can lock and unlock the mix level when browsing through presets.
  • Preset previous/next arrows, for quickly scrolling through presets.
  • New Cathedral presets.

The goal of ValhallaRoom is to be a useful "workhorse" reverb, for subtle drum rooms that can be felt more than heard, lush halls, dense plates, and big ambient decays. The algorithm designs have been influenced by some of the "classic" room simulation boxes, as well as state of the art modern theory.

ValhallaRoom by Valhalla DSP is my most favorite reverb. Its sound is just incredible; even after testing it against other reverbs quite frequently (yes, I do it once a year at least ... kind of some OCD ...). The controls are intuitive and the GUI is minimalistic as always with Valhalla plugins. The CPU consumption is low. There are even some algorithms included, which need even less CPU. While mentioning all this, especially when comparing to other products (just basically think of almost any reverb out there), it is even the most affordable reverb. Also it has no silly protection system with which you have to install third party stuff and also no dongle is needed. It's also interesting to mention that ValhallaRoom gets still updated and even gets some new algorithms from time to time. I just love this reverb.

Only thing that could get better is the preset system. It feels a bit clumsy sometimes, but you can work with it at least.

I never really felt the need to get a proper reverb (beside the daw-included ones), but testing v-room changed my mind. It immediately filled my music/mixes with room (hence the name). It's sounding natural and full, but still clear without making the mix muddy (that goes for all 9 reverb-modes without an exception).

Another important part is it's easy to use gui. Especially for a reverb-beginner like me it's clearly structured and has a helpful tooltip while the cursor crosses a knob/fader. Some may say the gui is to simple, but i really like the simplicity without any embellishment.

There are many presets included that can serve as a good start, but it's in the nature of reverbs, that it's used best with own adjustment, depending on music and the desired effect.

I must admit, that i'm not really an enthusiastic reverb-tester and my initial test of v-room was mostly based on the good reviews that it got in several forums, blogs etc. but i can't imagine there's much better value for money concerning reverb.

And regarding the fact that it got several new reverb-modes during it's development from 1.0.0. to 1.0.9. it seems also like a good investment in the future, as i'm sure there will be many more modes in future updates.

I used to underuse reverb until I heard the demo of this plugin. My reasons were that usually, I couldn't get 'musical results' or I was fearful of muddying up my mixes.

V-Room combats these symptoms by having a sound which seems to caress both your ears, and the dry source sound, whilst having enough controls to be simple to use, yet capable of anything from realistic ambiences, to pulsating walls of transparent sound, where time seems to stand still.

The modulation can be downright hypnotic. It's soothing and relaxing, and draws you into the soundfield, without ever sounding synthetic or obvious. As such V-Room is capable of chorus duties with minimal reverb times, and outperforms most chorus units in terms of sheer results.

V-Room is one of the few effect plugins that I would say feels like a musical instrument in-and-of it's-self. Parameters are easy to adjust smoothly in realtime, and you WILL play with the reverb depth, size, length, etc, while it runs, without the slightest hiccup.

I don't know how many algorythms this thing will finally have, but the latest addition, sulaco, is one of my favourites. It's mellow and 'woody'. Given the number of different reverb types, and just the right amount of parameters (which are common to each type), a lot of tweaking is possible. But if that's not your thing, there are an adequate amount of well chosen presets to get you where you need to be.

Resizable GUI is a big plus (good for freaking people out by suddenly exanding it while they're looking at it) and it's always plain to read and easy to tweak. Some may not like it's simple looks, but I don't mind them.
