# Envelope Follower Module

The Envelope Follower Module detects peak values in the Signal routed to its single Input Port and generates an envelope-following positive Signal which exponentially decays at a configurable rate.

For a key to understanding the tables on this page, see the Module Types page.

## Adding Input Ports

Adding input ports is not enabled for this module.

## Static Parameters

  # | Title | Type | Description
  0 | Decay Rate | Floating-point | Indicates how quickly the follower envelope, once triggered, decays towards zero. Larger values indicate a more rapid decay. Range: [0.005, 10.0], LOG

## Input Ports

  # | Title | Description | Input Scalar Used | Parameter Scalar Used
  0 | Input Signal | The input signal whose peak absolute values will be detected by the Envelope Follower | NO | NO

## Output Ports

  # | Title | Description
  0 | Output Follower Signal | This output signal is a positive envelope whose peaks duplicate the peak values of the Input Signal, followed by smooth exponential decay
