* "Duration (s)" determines how long the fade-in and fade-out should last

* ### Noisegate
*
* The `noisegate` plugin can be used to remove low volume noise.
*
* It has an "In" input port and an "Out" output data ports. Normally the input
* data is passed directly to the output.
*
* If the volume drops below "Close threshold", the noisegate will ramp down the
* volume to zero for a duration of "Release (s)" seconds. When the volume is above
* "Open threshold", the noisegate will ramp up the volume to 1 for a duration
* of "Attack (s)" seconds. The noise gate stays open for at least "Hold (s)"
* seconds before it can close again.
