DeClipper acting out of selected region

I just installed Audition and recorded something and now I want to start restoring the audio. I started with DeClipper, selected a heavily clipped part and in Settings I set the gain to -2 dB. Then I press Scan and then on Repair All. The problem is that this -2 dB gain is applied to the whole file, not to the selection only. Why's that? I can manually use Amplify first to get the -2 dB gain but why not do this in one single tool if it's actually there as an option in DeClipper? When I used Audition some years ago then it worked as expected and I used it quite a lot.

Still an issue in 14.4.038, maybe it's not a bug, but it feels like it should be able to work on a selection.

I checked - the bug report has been closed. This sort-of implies that the devs don't think it's a bug, even though it is, because a) it doesn't make sense and b) because it never used to behave like this. I have the ability to add a comment to the closed report, so I have. I have no idea what sort of hornet's nest I've just disturbed!

Yes, I can see it too, and I don't think that this is correct either; it should apply only to your selection - I'll report it as a bug in the morning.

I am though a little perplexed as to why you're making a bad recording in the first place and then trying to fix it? What benefit does this confer to the recording? Wouldn't it be easier to make a slightly less hot recording and optimise that?

Thank you very much for reporting it as a bug!

My background is that I digitalise old reel to reel audio tapes (and cassettes) and now when I started with this again after a long time, the first tape recording was some home made stuff and the person who recorded it in 1977 probably didn't have anything that would normalise the input levels or do some other fancy stuff available today. So when people started singing after some speaking, it was too loud and clipping, the input level was then notably turned down by the recording person, then back up to somewhere in between. And the inital loud part is that needs declipping. As it is with these old recordings, the volume levels are so uneven at times that getting the volume right over the whole recording is quite a lot of work 🙂 Envelopes are so useful. And add to it all the different hiss and noise reduction profiles that change during the recording, with or without FFT frequency cuts etc. -- So the more quickly and conveniently any of these tools works, the better and I definitely don't want the change of the volume over the whole recording.
