INTELLIGATE XR2000
3.5 Using the INTELLIGATE to change the sound
3.5.1 Reshaping sample sounds
With the help of the BEHRINGER INTELLIGATE, existing or new sampled sounds can be brightened up,
changed or used to create new sounds. The attack times and the dynamics of the sound can be changed as
desired.
3.5.2 Altering the texture of musical instruments
In addition, the INTELLIGATE can be used to change sound characteristics. For example, the quality of
ambience or reverberation created by an instrument within a room can be modified: when an instrument stops
decaying, the reverberation of the instrument falls below the user-defined threshold. The reverberation can be
controlled by using the threshold level and the release time control. The decay characteristics of the instrument
can be controlled using the release control, so that the natural characteristics of the instrument can be controlled
using the release control, so that the natural characteristics of the instrument are preserved or modified quite
radically.
4. SPECIAL APPLICATIONS
4.1 The INTELLIGATE as "De-Esser"
The "de-essing" function can be achieved by using a special application or frequency selective ducking. A
problem often encountered in recording, is the sibilant (Ssss) sound of the human voice. High frequency,
sibilant sounds and pops can procedure very high energy levels which can sometimes cause an otherwise
normal and undistorted voice to sound very harsh, shrill and sometimes unintelligible.
In order to reduce the problem associated with sibilance, a ducker can be used frequency consciously. The
unit responds only to selected frequencies and reduces the level temporarily, as soon as sibilant sounds or
pops are detected. If the detector circuit registers an excessive amount of high frequency information within the
programme material, the VCA is activated and the overall level is reduced. As this type of operation affects the
whole frequency range, this process is called broadband de-essing.
Please note that this type of frequency selective ducking is very different from simple fixed equalization using
notch filters, since de-essing has no effect on the signal except at the instant the sibilant occurs. The general
frequency response is principally not affected during this process.
When de-essing, insert the Key Filter section into the sidechain loop by depressing the FILTER switch. With
the help of the key listen function, the centre frequencies of the key filters are then adjusted exactly to match
the frequencies of the sibilant sounds. All other frequencies are filtered out, so that with maximum attenuation
of these frequency bands, along with a correctly adjusted threshold point, the unit responds solely to the
selected signal being produced by the equalizer. The level of sibilant sounds can therefore be effectively
limited.
