The IR Convolution Reverb plug-in series consists three products: the IR-1version 2,

IR-360 multi-channel surround sound reverb, and IR-L “Light” convolution reverb.

IR-1 version 2 is a sampling reverb that offers traditional reverb controls that

affect the impulse response sample itself rather than just filtering the resulting

sound. This approach retains the sample's signature sound but allows much

more flexible use than with conventional convolution reverbs.

The IR-360 offers surround sound capabilities by adding extra modules to

IR-1. It is the ideal reverb processor to use in sound for picture applications

from music, to mixing and sound design.

The IR-L is an entry level plug-in included with the IR-1 and IR-360 packages,

along with other Waves Bundles. Controls include Reverb Time with a ratio of

1:0.25; Convolution Start/Length controls; Direct in/out; Global pre-delay to

all IR components; Latency display and Dry delay; Dry/wet control; Crosstalk;

Output; and graphical display of IR properties.

◆ Both the IR-360 and IR-1 Version 2 allow you to capture the sound of

acoustic spaces and hardware devices by playing an included sweep

signal into an acoustic space or through an outboard processor and

recording the result. The software then allows you to import the

recording to create a custom impulse response that’s ready to use.

◆ The setting of each environmental parameter can generally be varied

from 0.25 to 4 times its natural value. For example, the user can vary

the RT60 (reverberation time) of an actual sampled space, and change

the size of that space.

◆ Samples of actual environments in the preset library employ a unique

combination of microphone array, including ORTF, and Soundfield

microphones mounted on a computer-controlled turntable, for

accuracy and realism.

◆ Venues include well-known spaces such as the Sydney Opera House,

Rome’s Santa Cecilia Concert Hall, Manhattan's Birdland jazz club, and

many more.

◆ Each space was sampled from multiple locations, at 96 kHz and 32-bit

floating point for maximum resolution, dynamic range, and SNR.

The IR1 Version 2 offers options to shape the decay envelope, change the reverb density,

analyze the frequency response and derive the room nodes, use de-correlation to optimize the

stereophonic character of the reverb, and add gain and pre-delay to each portion of the reverb

curve. Filtering techniques enable the damping to be precisely controlled, while a 4-band

parametric EQ allows tone adjustment of the reverberation. Addional features include a

Convolution Start Control that allows you to trim the beginning of a sample to eliminate

unwanted predelay; an ER (Early Reflections) Buildup Control for adjusting the buildup slope of

early reflections to control the attack sound of the transients; and a Dry Gain Mode that offers

adjustment of the wet and dry signal gains separately.

IR-360

Surround configurations for IR-360 include mono and stereo to 5-channel Discrete Surround

(doing 4 or 5 convolutions); mono to 5-channel Sound Field (3 convolutions); efficient stereo

to 5-channel Sound Field (3 convolutions); and full stereo to 5-channel Sound Field

(6 convolutions). In addition, two surround-to-surround options -- Sound Field Surround to

Surround (6 convolutions) and Efficient Discrete Surround to Surround (4 convolutions) employ

mixdown techniques to deliver the maximum practical benefit and efficiency. Both components

offer 5 to 5 and 5.1 to 5.1 with LFE passed to the output without additional processing.
