Description::
|
||
|
|
This is essentially the same as link::Classes/OnePole:: except that
|
||
|
|
instead of supplying the coefficient directly, it is calculated from a 60
|
||
|
|
dB lag time. This is the time required for the filter to converge to
|
||
|
|
within 0.01% of a value. This is useful for smoothing out control
|
||
|
|
signals.
|
||
|
|
|
||
|
|
For linear and other alternatives, see link::Classes/VarLag::.
