"where the effect always works on the selection only" -- That is controlled by a (somewhat ambiguous IMHO) setting in Prefs--Tracks > (Behaviors) > [ ] Select all audio in project, if none selected.

The worst thing about this is that that is the default Audacity behaviour - a really dumb default setting imho as it causes users (me included) to do stuff to the whole audio inadvertently (like deleting it accidentally - thank heavens for Undo)

I withdraw the suggestion as too limited for general use (but will keep it in my personal version as it really is quite useful if one is doing bulk LP conversion or the like).

Robert J. H. wrote:I assume that the profile is almost always either taken from the start or end of a track.

• Within the first (last) seconds of the track and not digital/dithered silence.
• above a certain threshold.
• not periodic i.e. some kind of noise.
• about 1 s long
