The InterVerb panel: the display with the reverb's tail, the EQ and the reverb's spectrum drawn together; MODEL with its list, the variants and the tail's length; TAIL with SYNC, DECAY and PRE-DELAY; EQ with FREQ, GAIN and Q for the band picked in the display; SPACE with WIDTH, DUCK, RELEASE and MIX; and OUTPUT in the footer

On the panel

The InterVerb panel with twelve numbered marks
  1. 1

    The display

    The reverb's tail and the EQ, drawn together as you turn the knobs, and the reverb's spectrum while sound plays. Drag an EQ node to move its band.

  2. 2

    Model

    Plate, Hall, Room or Special.

  3. 3

    Variants

    Three of each model, and Fresh air in Special.

  4. 4

    Length and first sound

    How long the reverb rings at 1 kHz, and when its first sound comes after the dry.

  5. 5

    Sync

    Puts DECAY and PRE-DELAY in time with the host.

  6. 6

    Decay

    How long the reverb rings, 0.1 to 16 seconds.

  7. 7

    Pre-delay

    Holds the reverb back after the dry, up to 250 ms.

  8. 8

    EQ

    FREQ, GAIN and Q of the band picked in the display, named beside the title.

  9. 9

    Width

    Spreads the reverb wider, or narrows it, and never touches the dry.

  10. 10

    Duck and release

    Keeps the reverb down while you sing or play, and sets how fast it comes back.

  11. 11

    Mix

    The reverb alone at 100%, for an aux return.

  12. 12

    Output

    The output level, -24 to +24 dB.

MODEL: pick the space

Four models: Plate, Hall and Room, with three variants each, and Special, whose first is Fresh air, an open, airy reverb for vocals. Each is my own, built to sound like a classic of its kind, and chosen by ear. Pick the model from the list and the variant below it.

Every variant is set to the same loudness, so switching does not jump in level. Switch variants between songs and the old tail rings out while what you play next goes to the new one.

TAIL: how long, and how soon

DECAY sets how long the reverb rings, from 0.1 to 16 seconds, shown as its time at 1 kHz. The lows and the highs move with it, so the variant keeps its own colour. Turn it while the reverb rings and the tail already sounding stretches or shortens with it, without a gap.

PRE-DELAY holds the reverb back after the dry, up to 250 ms on top of the variant's own start, and the dry stays on time. With SYNC on, both are in time with your session: DECAY from an eighth-note triplet to four bars, PRE-DELAY from a 1/64 to a quarter note.

The InterVerb panel with the display and TAIL lit and the rest dimmed: DECAY at 1.98 s and PRE-DELAY at 20.0 ms, SYNC off, and the tail's curve in the display behind the reverb's spectrum
Decay
0.1 to 16 s, the variant's own by default
Synced decay
1/8 triplet to 4 bars, 1/2 by default
Pre-delay
0 to 250 ms, 0 by default
Synced pre-delay
1/64 to 1/4

EQ: shape the reverb

A low shelf, a mid band with its Q, and a high shelf, on the reverb alone, so the dry is never touched. Drag a node in the display to move its band, or click it and set it with FREQ, GAIN and Q below. The display draws the EQ over the tail, so you see both as you turn.

The InterVerb panel with the display and EQ lit and the rest dimmed: the L, M and H nodes on a flat EQ over the reverb's spectrum, and the mid band's FREQ at 1000 Hz, GAIN at 0.0 dB and Q at 1.00
Low shelf
20 Hz to 1 kHz, 200 Hz by default
Mid
100 Hz to 10 kHz, 1 kHz by default; Q 0.3 to 6
High shelf
1 to 20 kHz, 5 kHz by default
Gain
±12 dB, 0 by default

SPACE: width, duck and mix

WIDTH is InterSilica's width, on the reverb alone: to the right it spreads wider, to the left it narrows towards mono, and the dry stays where it was.

DUCK is InterTape-delay's: it keeps the reverb down while you sing or play, and RELEASE sets how fast it comes back when you stop, so the reverb fills the gaps instead of blurring the words. MIX at 100% is the reverb alone, for an aux return.

SPACE with WIDTH at 0, DUCK at 4.0 dB, RELEASE at 400 ms and MIX at 100%
Width
-100 to +100, 0 by default
Duck
Off to 24 dB, off by default
Release
50 to 2000 ms, 400 ms by default
Mix
0 to 100%, 100% by default

And also

The whole tail, every time

InterVerb tells your host how long its tail is, so a render or a bounce keeps all of the reverb, and the host does not stop it while it still rings.

An output knob

The small knob in the footer sets the output level. Option-click it (Alt-click on Windows) for 0 dB. ACTIVE off bypasses it too, so you compare at the same level.

Light on a stereo bus

A stereo input goes into the reverb as mono and comes out in stereo, which keeps the CPU low. The dry keeps its panning.

New in 1.1.0

The reverb, made visible.

  • A spectrum of the reverb in the TAIL / EQ display. While sound plays, the reverb's output shows as a slow, smooth line behind the EQ curve, with the moment just gone trailing behind it and fading. It shows the reverb after the EQ and DUCK, before MIX, and fades away when the reverb falls silent.
  • The spectrum is drawn only while the panel is open, so a closed panel costs nothing.
  • The tail's lines are drawn in a darker green, so the spectrum and the EQ curve stand out from them.
