ADAPTIVERB was designed to sound beautifully lush and smooth from the ground up. Rather than simulating a realistic room, it focuses on creating depth, harmonic richness, and sustain that sounds so naturally organic it's as if your sounds had more sustain to begin with.

Its unique Bionic Sustain Resynthesizer creates reverb free of graininess or noise splashes, and its Ray Tracing engine creates super-dense and perfectly diffuse tails free of any attention-grabbing discrete reflections.

Applying long reverb tails is a great way to "carry" a sound and embed it into a mix. However, the length and amount of reverb you can successfully use for this effect is usually limited. Reverb tends to obscure detail by moving sounds into the background and it can introduce dissonance and tonal clashing when the tail overlaps with a note or chord change. This often results in a cluttered, "muddy" mix that lacks directness and tonal definition.

ADAPTIVERB is always in tune with the input or a user-defined set of pitches, filtering out all unwanted harmonic content from the reverb automatically. Bye bye, mud & clutter – hello, harmonic clarity!

Rather than stacking delay/allpass nodes or convolving the input with an IR (impulse response), ADAPTIVERB employs machine learning, ray tracing and source separation techniques to synthesize a reverb tail that automatically adapts to the audio context in which it is used – like a chameleon.

As a result, reverb timbre can be matched to the source automatically, and the reverb can blend with your sounds so seamlessly that it becomes "invisible" with minimal effort – great for adding "glue" in mixing and mastering applications without having to adjust roll-offs, frequency dependent decay times or crossover frequencies manually.

ADAPTIVERB loves sound design. Add fifth or octave interval harmonics into the reverb using the RICHNESS parameter, create additive synth style timbres using SIMPLIFY, create drones and pads that play without input using FREEZE, or create cross-filtering effects with the Harmonic Contour Filter's HOLD functionality – quickly, easily and at maximum quality. Whether you produce music or design sound for film and games, ADAPTIVERB is for you. Read more about ADAPTIVERB's pitch/synthesis, cross-filtering or drone/pad creation features...

At the heart of ADAPTIVERB lies the BIONIC SUSTAIN RESYNTHESIZER, a new type of reverb free of any harshness or graininess, which has no inherent resonant frequencies of its own, and that blends with the source excellently by nature. Built using an AI technique similar to that used to enable self-driving cars to avoid collisions, it synthesizes a reverb tail using a network of hundreds of oscillators that learn to re-create just the pitched/harmonic parts of the input sound.

Thus, noise and transients don't enter the reverb, making for organic tails even when working with otherwise difficult material like the master bus or field recordings.

As if that weren't cool enough, we've built in controls for tweaking these oscillators, for timbral manipulation from subtle to...quite dramatic.

SIMPLIFY reduces the number of oscillators the Bionic Sustain Synth uses from hundreds right down to one at the slider's maximum value. The result is a simplification of the timbre that has a distinct "flavor" somewhat similar to that of additive synthesizers. SIMPLIFY does not introduce the typical "warbliness" of additive synthesizers, though, due to the unique design of the resynthesis engine used. SIMPLIFY loves being automated, and works really well for creating ambient sounds.

ADAPTIVERB also features an advanced RAY TRACING REVERB module, which creates a very dense and perfectly diffuse reverb, with a beautifully smooth and full sound. Ray tracing reverb works by simulating the paths soundwaves take from a virtual sound source to a virtual listening position in a 3D room model. ADAPTIVERB's AI-based implementation simulates the effects of 16,000 such paths, without explicitly computing individual reflections.

The reverb created is linear ("white") across all frequencies – perfect for diffusion of the sound pre-filtered by the SUSTAIN RESYNTH, as well as for post-filtering using the HARMONIC CONTOUR FILTER.

The unique HARMONIC CONTOUR FILTER post-processes the output of the preceding sections. Its primary purpose is to remove those pitched parts from the reverb tail that would clash with the input, for example when the source track had a chord-change, or that would create “mud” or obscure the source too much, limiting the amount of reverb that can be successfully used in a mix.

The HCF also enables automatically adapting the tail to blend perfectly with the source, or, when applied with negative amounts, suppressing commonalities between the input and the reverb, to “fill just the gaps”.

Switching the HCF to KEYBOARD MODE allows conforming the reverb to a user-defined set of pitches, under control of a small on-screen keyboard that features 5 snapshots for chord storage and automation. Simply select which pitches are "allowed", and the entire effect path will conform. Pitch conforming can be done using precision filtering or pitch quantization, removing all unwanted harmonics or shifting them to allowed pitches, respectively. Both methods can be used to process the dry signal, too, by setting REVERB SOURCE and REVERB MIX to minimum values, for very cool sounding effects.

Use the HCF HOLD mode to create voice-colored reverbs, guitar flavored delays or other cross-filtering effects. Simply play a sound into the plug-in, and activate the HCF's HOLD function when you hear the timbre you'd like to impart onto ADAPTIVERB's effect path. Then, swap the input signal and cross-filter away! The HCF will extract or remove all components from the input or reverb that are not similar to the HOLD snapshot you took in terms of pitch. This source separation (a.k.a. De-Mixing) based similarity filtering engine is so precise that you can even use it to remove static sounds like hum, single notes or chords from your audio. A very powerful tool for sound design.

Using the input FREEZE it takes just seconds to create stunningly organic, evolving drones, pads and ambient textures, that play even without input and are stored with the preset – effectively turning ADAPTIVERB into a unique ambient texture synthesizer. Unlike other "infinite reverb" type functions that simply recycle the contents of the reverb, in ADAPTIVERB, the actual input signal before the reverb is captured, and resynthesized in a seamless manner that does not sound looped and is free of warbling artifacts typically associated with such functionality.
