Normalize resets when skipping back
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!
MPC-HC 2.2.0 OS Name Microsoft Windows 10 Pro Version 10.0.19045 Build 19045
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. gettysburg_johng_librivox.zip
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.
I am unable to reproduce the problem with the given sample. Give timestamp from where you seek and where to.

How did you jump back? With the arrow keys, or with the mouse? Because in the original issue it refers to the arrow keys, the behavior might be different with a large skip with the mouse on the timeline

I usually jump back with the left arrow key, but I also see the issue when I jump back with a mouse.

Last night when I was about halfway through watching an episode of Beacon 23 (TV series) in MPC-HC 2.2.1.48 (on Windows 10) using Sony WF-1000XM4 Bluetooth earphones, I pressed the left arrow key to jump back and replay something interesting, and the volume jumped up roughly 6 dB. As I continued listening, the volume went back down to what it had been before I jumped back.
How about giving me a build that logs any changes to audio gain? That might nail down the issue.
I reproduced the problem as described in my last Comment, this time recording the audio output with Audacity, which is attached to this Comment. Halfway through the clip (which is trimmed from the end of a much longer recording) I used the left arrow to jump back for replay. Note how much louder the replay is compared to the first time through. sample.zip
p.s. Here is an audio only file that reproduces the problem for me, matching the sample in my last Comment when I press the left arrow to jump back. UPDATE: Play from the beginning with my audio settings, press left arrow at about 2:15. (The time scale is not correct.) Beacon 23 S02E05.zip
ADDITIONAL INFO: I do not see this audio gain problem when playing through the laptop speakers, just when playing through my Sony WF-1000XM4 Bluetooth earphones.
It should be fixed in latest build, and if not you are out of luck, because I am not going to make any further changes.

I assume you're referring to development build 2.2.1.72, but I didn't see download links.
Thanks. On my sample, 2.2.1.72 till jumps up, but only about 7dB. On a previous version it had jumped up about 14dB. So, not perfect, but major improvement. Thank you.
UPDATE: I've now played some real videos, and was not able to reproduce the problem, so I hereby pronounce it FIXED in 2.2.1.72. Thank you! 👍 👏
