2.8. Envelope
Summary: The Envelope component applies a filter to an input signal based on
three math functions.
Description: The Envelope component applies a type of filtering to the input
signal. The type of filtering may be lowpass, bandpass, or highpass. The input
signal’s frequency, gain, and Q factor are calculated in the user-defined Control/
Math Function component.
