Densification

On the DENSIFICATION tab a cascade of sparse FIR filters produces 10,000 to 200,000 short, time-staggered copies of the input (set by count; fewer at depth max). A placement profile decides where those copies fall in time, and an envelope shapes their level over length. The stage returns the source at direct with the cascade at sheen beside it, and the header MIX crossfades between the incoming signal and that result.

TEXTURE

Control	Range	Default	What it does
sheen	0 to 50 %	35 %	Level of the cascade returned beside the source.
direct	0 to 100 %	100 %	Level of the source carried through the stage. At 100 % densification is additive; at 0 only the densified field remains. On a multichannel output the Density object places this source along with the cascade. EXPERT view.
count	10k to 200k	200k	Effective total tap count across the cascade at depth med or deep. At max it has no effect (see Cascade Depth). Lower counts thin the field and lighten the CPU load. EXPERT view.
shape	8 profiles	Golden	The tap-placement profile. See below.
depth	deep / med / max	med	How the cascade is split into stages. Drawn as three dots. EXPERT view. See Cascade Depth.
length	0 to 8 s	1.2 s	How long the densified field lasts. The SPACE tail has its own decay time, size.

sheen stops at 50 %. The cascade is a long, programmable comb, and past that point a cascade this dense dominates the spectrum and reads as comb filtering.

Tap-Placement Profiles

Each profile is a different law for placing taps in time. The tap count is the same across all eight, and only the placement changes.

shape	Placement
Regular	Dense at the start, thinning steadily toward the end
Golden	Close to even spacing
Even	The most uniform of the eight
Natural	Even coverage with irregular gaps
Branching	A self-similar pattern built from two gap sizes
Prime	Slightly front-weighted, with gaps that widen irregularly
Chaos	Clumped into irregular clusters
Voice	Bursts that thin out over the length

The late tail on the SPACE tab follows the active profile too. Its delay lengths shift with the profile, so changing shape changes the tail as well as the densified field.

Cascade Depth

depth sets how many filters the cascade runs in series and divides count between them.

depth	Stages	Character
deep	3	Smoothest, lightest on CPU
med (default)	2	Between the two
max	1	Sharpest per-stage character, heaviest on CPU

At max the single stage runs 3,001 taps whatever count is set to, so count only changes the sound at med and deep.

depth at max is the heaviest setting in ANTIVERB: at a count of 200k the densifier uses about three times the CPU it uses at med. On a single track it can use most of one CPU core even when the machine as a whole is lightly loaded. Use med or deep if the host reports overloads.

ONSET & SHAPE

In the host’s automation list, curve is called Shape and the shape knob on TEXTURE is called Character. Open [+] ONSET & SHAPE (EXPERT view) for the envelope and timing of the field. The envelope has three sections: a fall from 0 dB to drop over drop time, a flat plateau at drop for hold, then a curve down to -60 dB at length. Envelope times run from the input, and the taps fill the span from start to length.

Control	Range	Default	What it does
start	10 µs to 30 ms	40 µs	Delay before the first tap. Microseconds sound tight; tens of milliseconds give an audible gap.
lead	0.1 to 10 ms	3 ms	Window over which punch settles back to 0 dB. No effect when punch is 0, except at length 0 (see below).
hold	0 to 500 ms	100 ms	Length of the plateau.
jitter	0 to 10 %	2 %	Random offset of each tap within its local spacing; breaks up audible periodicity.
spacing	0 to 30 %	5 %	Difference between left and right tap positions. At 0 both channels carry the same field.
skew	0 to 100 %	50 %	Warps tap positions: below 50 % pulls taps toward the start, above 50 % toward the end. 50 % leaves the profile as it is.
curve	Linear / Soft / Sharp	Linear	Shape of the final decay. Soft holds up and drops late; Sharp drops early.
punch	-6 to +6 dB	0 dB	Lifts (positive) or softens (negative) the leading edge over lead.
drop time	5 to 100 ms	20 ms	Length of the first section.
drop	-24 to 0 dB	-6 dB	Level reached at the end of drop time, and the plateau level.

At length 0 the stage switches to a fixed 5 ms field. lead then sets how quickly that short field rises to its peak, and drop, drop time, hold, curve, punch and spacing have no effect.

TAMER (Resonance Smoother)

A dense comb leaves spectral peaks above the average, which ANTIVERB cuts in two stages (a fixed correction and the resonance smoother). Each time the cascade is rebuilt, ANTIVERB corrects its strongest peaks and notches. This correction is always on and has no controls. The resonance smoother under [+] TAMER (EXPERT view) acts on the moving signal. It compares each part of the densified output’s spectrum with the local average and cuts only where a peak rises more than threshold above it.

Control	Range	Default	What it does
amount	0 to 100 %	0 % (off)	How strongly peaks are cut. 0 passes the signal untouched; about 50 % is gentle. Above 0 the smoother adds 1,024 samples of latency, which ANTIVERB reports to the host.
mode	Stereo / Center+Sides	Stereo	Stereo smooths each channel on its own. Center+Sides works on mid and side separately, so centre resonances can be cut without narrowing the image. On a multichannel output the smoother always works channel by channel, so Center+Sides behaves as Stereo there.
threshold	0 to 24 dB	6 dB	How far above the trend a peak must rise before it is cut. Lower catches more peaks.
high	2 to 20 kHz	20 kHz	Upper edge of the range the smoother works in.
low	20 Hz to 2 kHz	100 Hz	Lower edge of the range the smoother works in.
tilt	-12 to +12 dB/oct	0 dB/oct	Tilts the reference trend around 1 kHz. Positive protects the highs; negative protects the lows.

MULTIBAND (Bass Split)

The two-band mode under [+] MULTIBAND (EXPERT view) splits the input at crossover with a 24 dB/octave crossover. The low band runs through a single sparse filter with its own tap count, set by low density, and the high band runs the full cascade, which keeps the bass articulate under a dense top.

Control	Range	Default	What it does
engage	off / on	off	Turns the bass split on.
low density	16 to 256	256	Tap count for the low band. Small values keep the bass tight; larger values add low-frequency density.
crossover	60 Hz to 1 kHz	300 Hz	Split frequency.

While the bass split is engaged, low cut (the densifier’s high-pass on the TONE tab) has no effect, since the high band already starts at crossover. The bass split works on a stereo output only. On a multichannel output the densifier runs unsplit and the three MULTIBAND controls do nothing.

Densifier EQ

The densifier’s EQ (top boost, low cut, dry top, dry top Hz) sits on the TONE tab. See Tone.

Some knobs carry a different name in the host’s automation list. See Parameter Reference.
