3. The dynamic settings can be adjusted with left or right arrows or by entering the desired number. The dynamic settings are defined as follows:
•
Threshold:
the signal level required to engage the Gate.
•
Attack Time:
amount of time to fully engage (Gate, De-Esser, Compressor, Limiter) after signal level increases beyond
the threshold.
•
Hold Time:
amount of time (Gate, De-Esser, Compressor, Limiter) is held after the signal level decreases below the threshold.
•
Release Time:
amount of time to fully disengage (Gate, De-Esser, Compressor, Limiter) after hold time has expired.
•
Range:
amount of gain reduction where -100 is totally off.
4. Graphic display of settings, the “T” is the Threshold that can be dynamically adjusted with a mouse.
5. The Gain Reduction (Range setting) shows Red when the Gate is engaging. In this example, the Gate is effectively shut because the signal is
below the Threshold setting required to open it.
De-Esser
1.
De-Essers are used when a high frequency (around 5000Hz) sibilance (S-sounds) are too pronounced in speech. The objective is to
reduce the sibilance at the frequency where it is too loud.
2. Enable the De-Esser and Active indicator.
3. Settings: Frequency (Hz), Sensitivity, Amount (dB), Hold Time (ms), Release Time (ms)
•
Frequency:
the target frequency where the sibilance (S-sounds) is most pronounced.
•
Sensitivity:
how much level at the target frequency is required to engage De-Esser.
•
Amount:
amount of gain reduction applied after De-Esser engages.
•
Hold Time:
amount of time the De-Esser is held after the signal level decreases below the sensitivity setting.
•
Release Time:
amount of time to fully disengage after hold time has expired.
Example method of setting a De-Esser:
First find the Frequency where the sibilance is worse case; start around 5KHz and move up/down with the “Amount” set high, +20dB or more to
emphasize issue. When the problem area is found, adjust the sensitivity so the De-Esser is only active when sibilance is present. Turn it up until it
is making the vocalist “Ss” and “Ts” hard to hear, then dial back a bit. Set the “Amount” (gain reduction) lower until it sounds more natural. “Hold”
should be longer than the sibilance & “Release Time” should typically be between 8 and 18ms, so it can’t be easily noticed.
4. The display can be used dynamically to move the curve while listening.
5. This meter shows the activity of the Gain Reduction in real time to help adjust as necessary.
