With Normalize enabled with Max Amplification 400% and Regain Volume not enabled, if I Skip Back (e.g., because I missed something), Normalize resets to Max, which can be unpleasant.
While I think it makes sense to reset when loading a different file, I don't think it should reset when skipping in the same file.
(I'd prefer not to lower Max Amplification because I have some files that need a higher value.)

Thank you for MPC-HC!

Regain has NOTHING to do with this. It simply resets the algorithm on seek.

I need a good sample file to analyze problem. And timestamps to seek from and to.

Thank you.
I understand that Regain has nothing to do with my issue. I confirmed the setting for your information.
To make it as easy for you as possible I'll create a synthetic video file that reproduces the problem.
That might take me a couple of days due to my current heavy schedule.
When I have it, I'll update this Issue.

@JNavas2 any news regarding the sample file?

Thanks for the reminder.
Attached is a public domain audio file that demonstrates the problem here.
I'm listening with Sony WF-1000XM4 earbuds over Bluetooth.
When I start playing with the audio quite loud, the volume gets automatically reduced as I play it.
Then if I jump back with the left arrow or to near the beginning from near the end,
the audio is suddenly as loud again as when I started playing.

Unfortunately, the problem is not fixed.
I was watching a long video in 2.2.1.48, and jumped back to review something, and the audio was much louder.
