CHAPTER 20. LIVE AUDIO EFFECT REFERENCE 273

higher value can sometimes improve the source's intelligibility, while a lower value may give

a smoother decay.

Spin applies modulation to the early reections. The X-Y control accesses the depth and

frequency of these modulations. A larger depth tends to provide a less-colored (more

spectrally neutral) late diffusion response. If the modulation frequency is too high, doppler

frequency shifting of the source sound will occur, along with surreal panning effects. Spin

may be turned off, using the associated switch, for modest CPU savings.

20.18.3 Global Settings

The Quality chooser controls the tradeoff between reverb quality and performance. Eco

uses minimal CPU resources, while High delivers the richest reverberation.

The Size parameter controls the room's volume. At one extreme, a very large size will

lend a shifting, diffused delay effect to the reverb. The other extreme  a very small value 

will give it a highly colored, metallic feel.

The Stereo Image control determines the width of the output's stereo image. At the highest

setting of 120 degrees, each ear receives a reverberant channel that is independent of the

other (this is also a property of the diffusion in real rooms). The lowest setting mixes the

output signal to mono.

20.18.4 Diffusion Network

The Diffusion network creates the reverberant tail that follows the early reections. The

decay time control adjusts the time required for this tail to drop to 1/1000th (-60 dB) of its

initial amplitude.

High and low shelving lters provide frequency-dependent reverberation decay. The high-

frequency decay models the absorption of sound energy due to air, walls and other materials

in the room (people, carpeting and so forth). The low shelf provides a thinner decay. Each

lter may be turned off to save CPU consumption.

The Freeze control freezes the diffuse response of the input sound. When on, the reverber-

ation will sustain almost endlessly. Cut modies Freeze by preventing the input signal from
