Valhalla DSP's are AMAZING!


VALHALLA DSP's ROOM

Valhalla's Room reverb, is SO good, I use it on EVERYTHING!


Valhalla Room

An Algorithmic Vision Of Perfection And Precision. It’s Grade A Class, Number One In Its Division.

ValhallaRoom is a versatile, true stereo algorithmic reverb. It features twelve original reverberation algorithms (including the latest Dark reverb modes, Nostromo, Narcissus, Sulaco and LV-426), and produces a wide range of natural reverberation sounds.  Sounds range from tight ambiences and rooms, through traditional hall and plate sounds, all the way up to vast modulated spaces. The algorithm designs have been influenced by some of the “classic” room simulation boxes, as well as state of the art modern theory.

ValhallaRoom has been designed from a psychoacoustic perspective. Instead of creating a simplified physical model of a simplified physical space, VRoom generates early and late acoustic energy that provides the spatial and phase cues needed to create an “idealized” room impression.


  • 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. The spread of energy between the stereo channels can be controlled over time, which helps preserve the input spatial image.

  • The GUI has been designed for easy navigation, and is inspired by Joseph Müller-Brockmann, NASA control panels, and Sesame Street.

  • Resizable GUI. Make it really big, or really tiny, or whatever suits you best.

  • New in 1.5.1: Redesigned GUI! Better use of space, and 2 user-selectable color schemes (Electric Blue and Old School).

  • A comprehensive preset browser makes saving, recalling and sharing settings easy.

  • Fully compatible with 32 and 64 bit DAWs (32/64 bit VST for OSX and Windows, 32/64 bit Audio Units for OSX, 32-bit RTAS for OSX and Windows, 64-bit AAX for OSX and Windows).

  • Twelve original reverberation algorithms:

    • Large Room. Designed to emulate big rooms with a wide spatial impression, with smooth “detuning” modulation.

    • Medium Room. Sparser than Large Room, with a more random modulation.

    • Bright Room. A lush, shinier-than-life reverb, with deep modulation and a somewhat slower attack.

    • Large Chamber. Smooth decay with consistent high echo density and subtle detuning modulation.

    • Dark Room. A hybrid between the grungy early digital reverbs and the modern algorithms found in ValhallaRoom, with reduced high frequency content, noisy yet lush randomized modulation, a HUGE spatial image, echo density ranging from grungy to dense while retaining clarity, and tons of mojo.

    • Dark Chamber. Similar to the original Large Chamber algorithm, but bigger and darker, with deeper detuning modulation.

    • Dark Space. A HUGE dark space, with a somewhat sparser early echo density and deep detuning modulation.

    • Nostromo. Deep, dark, echoing reverb. Very sparse early echo density, slow density build, random modulation, wide spatial image.

    • Narcissus. Dark, lush, wide, with random modulation that quickly builds into rich chorusing. The little sibling of Nostromo, but it is still big. Designed for low CPU consumption.

    • Sulaco. Dark with lush modulation, and a well-centered stereo image. The Late Size control can sweep the reverb from tight rooms to vast echoing spaces.

    • LV-426. A dark, deep space reverb, with the wide spatial image of Nostromo and Narcissus, but with a much higher initial echo density than either of those reverbs. LV-426 has a somewhat slower attack than the other modes, and has highly diffuse random modulation for lush decays.

    • Dense Room. Similar to Large Room, but with a denser distribution of early echos, and a tone that is brighter while still having the “darkness” of the Dark algorithms. Great for snare drums!


VALHALLA DSP's SHIMMER

Valhalla Shimmer

Come With Uncle And Hear All Proper!   Hear Angel Trumpets And Devil Trombones.   You Are Invited!

ValhallaShimmer is an algorithmic reverb designed for BIG sounds, from concert halls to the Taj Mahal to the Halls of Valhalla. All of the sliders have been designed to be tweaked in real time and have a smoothed response to avoid clicks when changing settings or automating the controls. At the same time, the algorithm has been highly optimized, so you get a huge reverb sound without straining your CPU.


At its core, ValhallaShimmer is a high quality reverberator, designed to produce a smooth decay, that is both dense and colorless. There are several reverberation modes available, to allow the user to dial in reverb decays of different sizes, ranging from smaller rooms to vast ambiences:

  • By adjusting the Feedback, Diffusion and Size controls, the attack, sustain and decay of the reverb signal can be fine tuned.

  • The modulation controls can be set to produce subtle mode thickening, glistening string ensemble-esque decays, and the distinctive random modulation of the older Lexicon hall algorithms.

  • Two tone controls and the Color Mode selector allow the timbre to be adjusted from bright and glistening to a more natural dark decay, similar to that produced by air absorption in large spaces.

In addition, ValhallaShimmer has the ability to pitch shift the feedback signal. There are 5 pitch shift modes available:

  • Single, where the feedback is shifted up or down by the Shift value.

  • Dual, where the feedback is shifted both up and down (in parallel) by the Shift value.

  • SingleReverse, where each grain is reversed before it is pitch shifted. This results in a smoother pitch shifting sound than the Single mode.

  • DualReverse. Similar to the Dual mode, but with reversed grains, for a smoother pitch shifting sound.

  • Bypass, which turns off the pitch shifting (useful for “standard” reverb sounds).

By setting the Shift amount to +12 semitones, and the Feedback to 0.5 or greater, the classic Eno/Lanois “shimmer” sound is produced (learn more about that here, here and here).  A wide variety of other sounds can be created by the algorithm, ranging from spring-esque reverbs to “reverse” reverbs, to glistening pitch shifted pads that are usually associated with high end hardware processors.

ValhallaShimmer is available to demo/purchase for OSX (AU/AU64/VST/VST64/RTAS/AAX) and Windows (VST32/VST64/RTAS/AAX).
