It may be better to “retire” Silence Finder than Sound Finder.
As you say, there is little difference between the two. The main difference is that:
Silence Finder: Places a point label before the start of the sound.
Sound Finder: Places a region label around the sound.
If Sound Finder had an option to place point labels then it would do exactly the same as Silence Finder (except for the weird placement of the final label in Silence Finder).
I have started a new topic about the proposed changes to Sound/Silence Finder so that it can be discussed separately from this “Advanced Sound Finder” topic.
I have also included a poll in the remote hope of gathering some feedback about the proposed changes.
