EnvShaper
DCAM EnvShaper takes a different approach to dynamics processing than a standard
compressor. It allows you to adjust the attack and sustain portions of transients in order to
change the dynamic shape of a signal.
Detection Signal section
Input
The
Input
control allows you to switch between the left channel, right channel and both channels
of an incoming stereo signal to use as the input to the EnvShaper's amplitude detection circuit.
Using only one channel in a complex stereo signal can achieve better results.
HP Freq
The
HP Freq
control allows you to apply a variable high pass filter on the key signal that is used
for the amplitude detection circuit. This control is useful when there is too much low-end in the
signal fed into the peak detection circuit, which can result in the transient shaping reacting too
heavily.
Listen
Activating the
Listen
button allows you to monitor the signal used for the EnvShaper's detection
circuit.
Dynamics section
Attack
The
Attack
control adjusts the intensity of the attack phase of detected peaks in the audio signal.
Increase the control to intensify attack transients, and decrease it to soften transients.
Sustain
The
Sustain
control adjusts the intensity of release portions of detected peaks in the audio signal,
which increases or decreases the apparent sustain of sounds in the signal. Increase the control
for more sustain, and decrease it for less sustain. This control is useful for adjusting the perceived
level of ambience in a channel. Negative settings can produce damping effects for drum sounds.
Signal Bias
The
Signal Bias
control adjusts the sensitivity and release characteristics of the EnvShaper. At
low settings (towards the Fast setting) it is more sensitive to short transients while at higher
settings (towards the Slow setting) it is more sensitive to longer transients (towards the Slow
setting).
