Figure 10-68 Block diagram of Triggered Envelope Filter
The time constant of the envelope follower may be set (Env Rate) as well as the decay rate of the generated
envelope (Rel Rate). After the detected envelope rises above the Trigger level, a trigger event cannot occur
again until the signal drops below the Retrigger level. In general, Retrigger should be set lower than the
Trigger level. A level meter with a trigger marker is provided.
Parameters

Wet/Dry The amount of modulated (wet) signal relative to unaffected (dry) signal as a percent.
Out Gain The overall gain or amplitude at the output of the effect.
FilterType The type of resonant fi lter to be used. May be one of “Lowpass”, “Highpass”, “Bandpass”,
or “Notch”.
Min Freq The base frequency of the resonant fi lter. The fi lter resonant frequency is set to the base
frequency while the signal envelope is below the threshiold.
Max Freq The frequency of the resonant fi lter that can be reached when the envelope follower
output reaches full-scale. The resonant frequency will sweep with the envelope from the
base frequency, approaching the limit frequency with rising amplitudes.
Resonance The resonance level of the resonant fi lter. Resonance sets the level of the resonant peak (or
the amount of cut in the case of the notch fi lter).
Trigger The threshold at which the envelope detector triggers in fractions of full scale where 0dB
is full scale.
