The original convolution reverb

Altiverb is a plug-in that makes your audio sound as if it was played back somewhere else, adding the acoustics of existing spaces to your own recordings or to your live audio. All spaces in Altiverb were recorded in the real world, from Sydney Opera House to a Scottish underground oil tank the size of a cathedral.

Features

Apart from the extensive library of impulse responses you get with this plug-in, Altiverb features some clever controls for shaping the sound of this convolution reverb.

Decay

This essential reverb parameter is very prominent in Altiverb 8. You can apply an exponential decay on any impulse response to reduce the reverb time, without changing the character of the room.

Brightness

Real spaces often contain less high frequency content than algorithmic (synthetic) reverbs. Sometimes you need that extra sparkling brightness in a reverb tail that is just hard to obtain from the real world.

Damping

Control the reverb length of three separate and adjustable frequency bands. Shortening is damping, lengthening is enhancing. You can see the effect of damping in the waterfall graph of the impulse response.

Stage positions

Altiverb can have mono or stereo inputs. When making impulse responses, we used either one speaker position in the center of the stage for mono input, or two speaker positions for stereo input. So there is a direct relation between the amount of inputs and the speakers used. Using the positioner tab, available only in mono and stereo input Altiverbs, you can switch on the speaker, in which case you can hear where it stands. You can also, right there, move the speaker around.

Equalizer

Altiverb features a four band equalizer. The bass and treble bands are Baxandall EQs, designed to not shift phase more than 180 degrees, which effectively means that combing or cancellation effects are unlikely when the EQ’d signal is mixed with the dry signal. The equalizer works on the wet signal only.

Size

Makes the selected room (impulse response) smaller or larger. This transposes room modes and resonances, tightens or spreads early reflections, and shortens or lengthens the reverb tail.

Pre-delay

Delays the onset of the reverb. If the note symbol is clicked, the timing of the delay is locked to the tempo of the host application so you can select an eighth-note as the delay time.

Cloud Size and Pan Tracking Reverb - from LCR up to 9.1.6 input Altiverbs

Altiverb XL supports more than two inputs. With more then two inputs there is no longer a direct relation between an input and a speaker that was used when making the impulse response. Therefore the Positioner tab is unavailable. Instead there is a new control: cloud size. With cloud size turned down, the reverb no longer outputs to all output channels, it starts clustering around the input pan position of your sounds. Even when the input sound moves, the reverb cloud travels along with it.

Attack

Fades-in the start of the impulse response, resulting in a more lush, distant reverb sound.

Reverse

The entire impulse response is reversed in time for backward reverb effects.

Modulation

This effect does not emulate anything that happens in reality, it emulates something that happens in artificial reverb algorithms.

Gated Reverb

Allows you to abruptly cut-off a reverb after a set amount of time. The gate time can also be locked to the tempo of the host application.

Mixer

Everything is recorded with enough microphones to provide Atmos reverb (up to nine eye level speakers plus six over head channels).

There's a new output meter and a mixer that provides full control of all outputs.

Snapshots

Snapshots are presets that are private to an instance of Altiverb.

WHAT IS NEW IN ALTIVERB 8

Native Apple silicon

M1 / M2 & Intel macs are fully supported.

Dolby Atmos support

Up to 9.1.6 input and output channels for fully immersive convolution reverb. 

New scalable user interface

(except AU version)

Cloud size

Automatic input-pan following reverb, locate each reverb around the panning of the source, even when multiple sources move in a single instance.

Smooth and clickless

IR switches, reverb adjustments and stage position changes all practically seemless without any clicks.

New output level meters

These allow manipulation of level and delay per output channel.

Pure Dolby Atmos IRs

Almost all of the hundreds of the music spaces (concert halls, churches, cathedrals, studios, scoring stages) have been upgraded to Dolby Atmos by utilizing the original extra recordings we have been routinely making throughout the years.
All outputs of Altiverb are always real and distinct original speaker to microphone takes.

Mono pan following

Across surround busses up to Dolby Atmos (9.1.6), making multi-mono instances unnecessary, reducing session load time considerably.

Improved IR searching

The newly designed browser offers more and quicker ways to find the right IR.

New IR Tool

This tool enables you to create your own IRs, with output support up to 9.1.6 channels.

Computer activation

The Altiverb license can be activated on a computer or on a USB iLok key. The iLok USB key is NO LONGER required.

VST3 Plug-In

To ensure compatibility with worldclass VST host applications (DAWs) like Ableton Live, Cubase, Nuendo and Digital Performer Altiverb 8 features a VST3 plug-in.

Center

Almost all IRs have been supplied with a real center channel for LCR or 5.0 7.0 without center bleed.

New Spaces

many new spaces are included with Altiverb 8, like the Zuidervermaning from the intro video, a dance club, some industrial spaces, a Tesla, camper vans , atmos plates and springs reverbs, and a selection of buckets and bins including a porta toilet. All including atmos.

improved loading speed.

Your sessions with many Altiverbs will load quicker than ever.
