Convolution Reverb effect
The Reverb > Convolution Reverb effect reproduces rooms ranging from coat closets to concert halls. Convolution-
based reverbs use impulse files to simulate acoustic spaces. The results are incredibly realistic and life-like.
Because Convolution Reverb requires significant processing, you may hear clicks or pops when previewing it on
slower systems. These artifacts disappear after you apply the effect.

Convolution Reverb options
Impulse Specifies a file that simulates an acoustic space. Click Load to add a custom impulse file.
Mix Controls the ratio of original to reverberant sound.
Room Size Specifies a percentage of the full room defined by the impulse file. The larger the percentage, the longer
the reverb.
Damping LF Reduces low-frequency, bass-heavy components in reverb, avoiding muddiness and producing a
clearer, more articulate sound.
Damping HF Reduces high-frequency, transient components in reverb, avoiding harshness and producing a warmer,
lusher sound.
Pre-Delay Determines how many milliseconds the reverb takes to build to maximum amplitude. To produce the
most natural sound, specify a short pre-delay of 0–10 milliseconds. To produce interesting special effects, specify a
long pre-delay of 50 milliseconds or more.
Width Controls the stereo spread. A setting of 0 produces a mono reverb signal.
Gain Boosts or attenuates amplitude after processing.
Full Reverb effect
The Reverb > Full Reverb effect is convolution-based, avoiding ringing, metallic, and other artificial sounding
artifacts.
This effect offers some unique options, such as Perception, which simulates room irregularities, Left/Right Location,
which places the source off-center, and Room Size and Dimension, which help you realistically simulate rooms that
you can customize. To simulate wall surfaces and resonance, you can change the reverb’s frequency absorption by
using a three-band, parametric EQ in the Coloration section.
Note: The Reverb effect demands significant processing; for real-time, multitrack use, either freeze this effect or replace
it with Studio Reverb. (See “Freeze effects and improve performance” on page 109.)
When you change reverb settings, this effect creates a new impulse file, which simulates the acoustic environment
you specify. This file can be several megabytes in size, requiring a few seconds to process, so you might have to wait
before hearing a preview. The results, however, are incredibly realistic and easy to tailor.
