Reverb effect

The Reverb > Reverb effect simulates acoustic spaces with convolution-based processing. It can reproduce acoustic or

ambient environments such as a coat closet, a tiled bathroom shower, a concert hall, or a grand amphitheater. The

echoes can be spaced so closely together that a signal’s reverberated tail decays smoothly over time, creating a warm

and natural sound. Alternatively, Pre-Delay Time can be adjusted to give a sense of room size.

Relative to the Reverb effect, the Full Reverb effect provides more options and better audio rendering. For quick

adjustments, however, you may prefer the reduced options set of the Reverb effect.

Important: The Reverb effect demands significant processing; for real-time, multitrack use, either pre-render this effect

or replace it with Studio Reverb. (See

“Pre-render track effects to improve performance” on page 64.)

Decay Time Sets how many milliseconds it takes for reverb to tail off to infinity (about -96 dB). Use values below 400

for small rooms, values between 400 and 800 for medium-sized rooms, and values above 800 for very large rooms, such

as concert halls. For example, enter 3000 milliseconds to create reverb tails for a giant amphitheater.

To simulate rooms that have both echoes and reverb, first use the Echo effect to establish the size of the room, and then

use the Reverb effect to make the sound more natural. A Decay Time as little as 300 milliseconds can add perceived

spaciousness to dry sound.

Pre-Delay Time Specifies how many milliseconds reverb takes to build to its maximum amplitude. For a short Decay

Time, the Pre-Delay Time time should also be smaller. In general, a value about 10% as long as the Decay Time sounds

most realistic. However, you can create interesting effects by using a longer Pre-Delay Time with a shorter Decay Time.

Diffusion Simulates natural absorption, reducing high frequencies as the reverb decays. Faster absorption times

simulate rooms full of people, furniture, and carpeting, such as nightclubs and theaters. Slower times (over 1000

milliseconds) simulate empty rooms such as auditoriums, where high frequency reflections are more prevalent.

Perception Changes the characteristics of reflections within a room. Lower values create smoother reverb without as

many distinct echoes. Higher values simulate larger rooms, cause more variation in reverb amplitude, and add

spaciousness by creating distinct reflections over time.

A Perception setting of 100 and a Decay Time of 2000 milliseconds or more creates interesting canyon effects.

Dry Sets the percentage of source audio to output. In most cases, 90% works well. To add subtle spaciousness, set the

Dry percentage higher; to achieve a special effect, set the Dry percentage lower.

Wet Sets the percentage of reverb to output. To add subtle spaciousness to a track, keep the Wet percentage lower than

the Dry percentage. Increase the Wet percentage to simulate greater distance from the audio source.

Sum Inputs Combines the channels of a stereo or surround waveform before processing occurs. Select this option for

faster processing, but deselect it for fuller, richer reverb.
