Reflected Sound
In a typical concert hall, sound reaches the lis-
tener shortly after it is produced. The original di-
rect sound is followed by reflections from the
ceiling or walls. Reflections that arrive within 50
to 80 milliseconds of the direct sound are called
early reflections. Subsequent reflections are called
late reverberation. Early reflections provide a
sense of depth and strengthen the perception of
loudness and clarity. The delay time between
the arrival of the direct sound and the begin-
ning of early reflections is called the pre-delay.
The loudness of later reflections combined with
a large pre-delay can contribute to the percep-
tion of largeness of an acoustical space. Early re-
flections are followed by reverberation and re-
petitive reflections and attenuation of the
original sound reflected from walls, ceilings,
floors, and other objects. This sound provides a
sense of depth or size.
D-Verb provides control over these reverbera-
tion parameters so that extremely natural-
sounding reverb effects can be created and ap-
plied within Pro Tools.
D-Verb Parameters
D-Verb has the following parameters and con-
trols:
Output Meter
The Output Meter indicates the output level of
the processed signal. For the stereo version of
D-Verb, it represents the summed stereo output.
It is important to note that this meter indicates
the output level of the signal—not the input
level. If this meter clips, it is possible that the
signal clipped on input before it reached
D-Verb. Monitor your send or insert signal levels
closely to help prevent this from happening.
Clip Indicator
The Clip Indicator shows whether or not clip-
ping has occurred. It is a clip-hold indicator. If
clipping occurs at any time during audio play-
back, the clip light will remain on. To clear the
clip indicator, click it. With longer reverb times
there is a greater likelihood of clipping occur-
ring as the feedback element of the reverb builds
up and approaches a high output level.
