You will ride eternal, shiny and chrome.

ValhallaPlate is our algorithmic take on the classic plate reverberation sound.

Twelve original algorithms emulate the sound and behavior of real world steel plate reverbs, and take the sound into dimensions that physical plates can’t touch.

Now updated to version 1.6.8 (Mac) / 1.6.3 (Windows)! Intel/M1/M2/M3 native Mac builds – ready for Sonoma, signed installer for Windows

Plugin UI
















The MODE control in Valhalla Plate is a super powerful, high-level control that allows you to switch between 12 different reverb algorithms.

This is a good starting point for the plugin. This is a fairly neutral sounding plate. The attack is not super sharp, and the tone is kinda bright, but not too bright.

Similar to Chrome, but darker.

Much sharper attack than the first 3 modes. If you listen to the signal 100% wet, it almost sounds like there is some dry signal in there. This is a characteristic of some of the plates we heard during the development process. The tonality is fairly bright.

This has a deeper attack than both Chrome and Steel (i.e., the sound seems to come from a more distant sound source). The tonality is fairly dark. There is a bit of resonance in the very low midrange, that was dialed in from a specific EMT140 we tested at Avast Recording here in Seattle. Most of the other Valhalla Plate modes were deliberately designed to have a more neutral tonality, but this low midrange resonance was key to getting close to that specific sound.

(New in Version 1.5.0): Mono-in, stereo-out mode, with the dense upper midrange and lower modal density found in older plates. Lower modal density, with lots of high frequency “air.”

(New in Version 1.5.0): Mono-in, stereo-out mode. Darker tone color than Adamantium.

(New in Version 1.5.0): Mono-in, stereo-out mode. Dark tone color, with a booming low end that is befitting of the densest metal found in nature.

MUCH higher modal density than the first 4 modes. With the SIZE parameter set >100%, Aluminum can sound much more like a chamber than a plate. There is a slight metallic sound to a well-tuned plate, that the first 4 reverb modes have. Aluminum (and Copper & Unobtanium) have less of this metallic sound and can sound much clearer. The overall tonality of Aluminum is fairly bright.

High modal density, but deeper and darker than Aluminum. The sound seems to come from deep within the plate. Set the SIZE up to 200%, add a touch of modulation, and you have an open sounding reverb that works on almost any source material.

High modal density, bright, with a longer high frequency decay than the other plates. This is my take on the Ecoplate sound but without the metallic ringing artifacts. Turn up the modulation, and you have a perfect reverb for synths.

(New in Version 1.5.0): A chamber/plate hybrid that uses the equivalent of two parallel mono plates to preserve the stereo image of your input signal.

(New in Version 1.5.0): A lush chamber/plate hybrid, with a unique approach to the stereo image that is inspired by the “stereo” chambers found in some recording studios. Helps to preserve the input panning of signals, while still having a realistic fill of the stereo image over time.
