Ducker
The ducker is a kind of “sophisticated switch” allowing to attenuate or switch off automatically the
signal arriving in input A when a chosen level (in dB) is perceived in input S.
By double clicking on the Ducker icon the following window appears:
Ducker Parameters
Parameter Range Comment
Bypass Button Switches off the Ducker’s operations
Active LED, lit green Flashes when the Ducker is active (Signal has been detected on
input S)
Thd. (Threshold) (dB) 60.0 to
20.0 dB
Threshold of detection on the input (S).
The input (A) is attenuate when input signal (S) goes above this
threshold.
Advice : To avoid unexpected attenuation, don't set a low threshold
level
Response time 0 to 5000 ms Adjust the time between the S level's detection and the beginning
of the Ducker’s operation on the A signal.
Advice : Don't set a long "response time", otherwise you won't hear
the beginning the (S) signal (as the first words of the speech).
Attack time (ms) 0 to 1000 ms Adjust the fade-in time of the (A) signal when Ducker’s is working.
Hold time 0 to 5000 ms Adjust the time between the end (S) level's detection and the end of
the Ducker’s operation
Advice : Set enough "Hold time" to avoid unexpected background
level during the speech's breaks.
Release time (ms) 10 to
10000 ms
Adjust the fade-out time of the A signal when Ducker’s is no longer
working
Audio Depth (dB) -100 to 0 dB Adjusts the A level when the Ducker is active.
Speech gain (dB) -60.0 to+ 20.0
dB
Adjusts the S level when the Ducker is active.
