SPATIO Suite
Five distinctive algorithmic reverbs for natural spaces and creative effects.

Part of the SPATIO series of algorithmic reverbs, SPATIO Inverse creates a reverberant response that rises progressively in level instead of decaying in the conventional way.
Popularised in the 1980s, particularly on snare drums, this distinctive swelling effect is ideal for transitions, dramatic accents, percussion and layered sound design. While natural reverberation loses energy over time, SPATIO Inverse deliberately reverses this profile, building towards a precise and clearly defined ending that adds tension, movement and anticipation to the source.

The defining characteristic of inverse reverberation is the shape of its impulse response (IR). An impulse response describes how a system reacts over time to an extremely short excitation and provides a complete representation of its temporal and spectral behaviour.
In a real acoustic space, the impulse response normally consists of the direct sound, a sequence of early reflections and a progressively diffuse reverberant tail. Its overall energy envelope decreases approximately exponentially over time (Fig. 1), as sound is gradually absorbed by surfaces, objects and the air itself.
An inverse reverberator deliberately departs from this natural energy profile. Instead of continuously losing energy, its impulse response is shaped so that the later portion becomes progressively stronger (Fig. 2). The resulting response does not represent a physically plausible room: it produces a deliberately artificial behaviour in which the reverberant field appears to accumulate energy rather than dissipate it, creating a distinctive contrast between the original sound and its evolving ambience.

SPATIO Inverse plugin is absolutely the best one I used on vocals for this kind of effect.
Beautifully conceived, Anwida plug-ins never disappoint. Highly recommended!
I really like this reverb. Especially unique among reverb plug-ins are elements like plates and gates, they sound wonderful. The DX Reverb is a model plug-in with a lot of substance rolled into an intuitive, compact UI. Great job!
I particularly like the plates – they’re nice and silky with voice, and aggressive with snares – but the halls are equally satisfying…This fine-sounding reverb is versatile enough that you’re bound to find something that works for you among the 47 presets. If not, a little tweaking will get you there
SPATIO Room, to my ears, rules above all the other small room verbs…I’m now using this on pretty much everything. It adds just the right amount of presence to a sound without being obvious or overbearing. Whatever you did, it just works.
This freeware verb is frighteningly good! If nothing else, it’s absolutely worth the time for the free download. This little reverb sounds simply amazing…
