fade control

Hi, I would like to find a plugin that allows you to control the fade by choosing the starting point, the way it has to fade maybe by setting a graphic curve. In practice, a plugin that allows you to “draw” the progress of the increase or decrease in the level of an audio track.
Maybe there is a plugin that allows these controls?

Thanks,

G.

It doesn’t have the nice graphic interface that you would like, but it gets the job done: Adjustable Fade - Audacity Manual

Thanks, the plugin works fine, it was among those disabled.
There are several predetermined shapes to choose from.

Thanks,
G.
