t
Pre Delay
: This is the apparent distance the sound travels to the reflecting walls 
and back.
t
Absorption
: This assesses how much of the sound is absorbed (not reflected).
t
Mix: 
This is the amount of reverb.
These are the additional controls:
t
Size
: This refers to the apparent relative size of the room.
t
Density
: This is the density of the reverb “tail.” The higher the Size value, the 
greater the Density range (from 0% to 100%).
t
Lo Damp
: Adjust this to dampen low frequencies to prevent the reverb from 
rumbling or sounding muddy.
t
Hi Damp
: This dampens high frequencies. A low Hi Damp setting makes the 
reverb sound softer.
A treasure trove of VST plug-ins
Reverb’s rack of control knobs signals that this is a Virtual Studio Technology 
(VST) plug-in. These are custom-designed audio effects that adhere to a standard 
set by Steinberg audio. Invariably, those who create VST audio effect plug-ins want 
them to have a unique look and offer some very specialized audio effects. Many VST 
plug-ins are available on the Internet.

LESSON 13
Sweetening Your Sound and Mixing Audio
Trying stereo and 5.1 surround sound effects
The mono audio effects collection is a subset of the stereo and 5.1 effects. Those 
multichannel effect groups have additional effects that relate to their extra chan-
nels. You’ll see here how they work in this exercise:
1
Open Lesson 13-2.prproj.
2
Drag Music Stereo.wav from the Project panel to the Audio 1 track in the 
sequence. In this project, the Audio 1 track is set up as a stereo track.
