This tracks an incoming signal and outputs the result.
The rate controls tell the plugin how quickly to respond to a change in
input. Low values will mean a slower response - a setting of 0 will hold the
last value, and a very high value will track the input exactly.
Attack rate is how quickly an upward change is tracked, and Decay for
downward changes. There are two pairs of these - the one used depends on the
level of the Gate.
Example uses:
-
An envelope tracker- use the ‘Gate Low’ track rates with
the Gate held low, and run the output through a full-wave rectifier (an ABS()
operator) to get an estimate of the level of a signal.
-
Sample and Hold- run a narrow pulse wave into the gate, set the
‘Gate High’ rates to maximum, and the ‘Gate Low’
rates set to 0.
-
Track and Hold- run a variable pulse wave into the gate, set the
‘Gate High’ rates to 0, and the ‘Gate Low’ rates set
high. Varying the pulsewidth will vary the time the input is tracked, and
when it is held.
