Progressive amplification

Is there a way (or a plugin) to amplify a sound progressively: I mean a sort of fade in ora fade out which starts or stops at a certain amount of volume...

You can drag-select and apply Effect > Fade In or Effect > Fade Out.

You can also use the Envelope tool (two white arrows and bent blue line) to create a custom fade and there you can define both ends.

Those blue lines are rubber bands and you can push them around to do whatever you want.

Maybe I don't explain well what I meant.
The "Fade in" effect increases the volume from silence to "X".
I have a track with "x" volume and I want to amplify it progressively (not instantly, so I can't use the "amplify" effect) from "x" to "x+7"...

As Koz suggested: use the envelope tool - see: http://manual.audacityteam.org/man/Envelope_Tool

There is also this Nyquist plug-in that seems to match your description: http://forum.audacityteam.org/viewtopic ... 42&t=40900
