» Sigmund really blew my mind as it goes far beyond a standard delay plug-in «
» D16 Group is one of the most innovative tools to date. «
» When I think of D16, two things come to mind. The first is great, professional grade sounding plugins. The second, is not only intuitive, but fun interfaces. «
» All plugs of D16 are powerfull and if you like big sound as i, use Lush-101! «
» I love the rich bold quality of your plugins. «

Space Modulated Reverb

Owner's manual:


When creating Toraverb, we did not base it on any current reverb unit available in the market. We did not implement any “off-the-shelf” algorithm. Toraverb is not a classic type reverb unit like spring, room, hall or plate. Toraverb is a concept algorithm reverb. Using a set of easily accessible parameters, it allows the user to create practically ANY type of reverb.

Our goal was to create a reverb which would sound pleasant to the listener and the output could be tweaked in many different ways by the user.

Critical effect in any studio

Reverb is a critical effect in a mix. Final results depend on the reverb algorithm used and the quality of the implementation. Usually reverb is used as a send effect in which many channels in a mix are routed to it. If a low quality plug-in or hardware unit is used, the end results can sound very disappointing with the reverb tail sounding like it had been “ripped-off” in the mix.

High quality of diffusion

In Toraverb, we applied diffusing algorithms of the highest possible quality based on modified all-pass filters. By doing this and using properly tuned parameters, we can almost entirely eliminate unwanted flutter echo effects for every sound source.

Separate equalisation for early and late reflections

Toraverb is equipped with two independent, single band, fully parametric equalisers. One is used to EQ early reflections and the other to EQ late reflections. This is an incredibly useful feature which allows a lot of control over the character of the reverb to give the most natural sound.

Modulated tail

Toraverb also has an additional modulation parameter which affects the diffusing filters. These are responsible for the distribution of the sound waves reflections in time. By changing the modulation, the sound of the reverb tail can be altered to give a more realistic effect of sound propagation.

Spatial reflections

To give a better impression of physical space, we have added an innovative spatial reflection algorithm to Toraverb. It improves spatial reflections by allowing cross-talking of reflected stereo waves between stereo channels. This models what happens in the real world when a sound audible only in the left ear is reflected and is heard in both ears.


Toraverb is a very versatile reverb unit. The high sound quality, flexible sound shaping capabilities and ease of use will be appreciated by every producer and sound engineer. Try it out – we know you will love it!

» All our testing can be summed up quickly: the SilverLine series is outstanding and unique in sound quality. – you might have realized this by our kind of passionate writing as well. [...] your production will get a lot more precious character with these – in fact, that’s all SilverLine is about: giving a special touch to the sound, not being just another standard plugin series. «

» If you were looking for a huge hall setting, then you'd probably be better off using a decent convolution reverb, but for more effect-type uses, and creating rich ambiences that makes sound really stand out, this reverb is brilliant, and an absolute bargain! (read whole review) «
Wusik Magazine, March 2010
» Kudos to d16 for creating such a good sounding reverb. The addition of the 'Modulation' parameter is a nice touch. Toraverb is great and musical. It has a character of its own - undeniably 'unique' [...] With its sound and cheap price you can't go wrong. This is a must buy! «
Beat, April 2010
» Müssen wir Toraverb mit drei Adjektiven beschreiben, wurde unsere Wahl auf "hervorragend klingend, flexibel and intuitiv" fallen. Besonders gefallen hat uns der eigenständige Klangcharakter des Effekts, der ihn auch zu einem leistungsfähigen Sounddesignwerkzeug macht. «
Computer Music, (146) December 2009
» In fact, since installing it, it’s featured in every track we’ve done. What higher praise can we offer? [...] D16 Group deserve full marks for bringing us a reverb of such quality at such a ludicrously miniscule price. «
Waveformless, 8/2009
» So does D16 bring something new to the table here? I think so. There are many other algorithmic reverbs out there in plug-in form, but none that I've heard that have such a distinctive sound. [...] I almost see Toraverb as a 'sound design' reverb. I wouldn't necessarily use it for items where I just need some subtle space, but when I want the reverb to add to the 'wow factor' of the sound, Toraverb is going to be my first stop from now on. «
Buenasideas, Jul. 30, 2009
» Toraverb ist eines der realistischsten und eindrucksvollsten Reverb-Plugins und steht qualitativ auf einer sehr sehr hohen Stufe. Der Klang ist sehr klar und brillant, zudem bietet das Toraverb-Plugin aber auch die Möglichkeit richtig abgefahrene Hall-Effekte zu erzeugen. «
