Beatrice Voice too quiet in some parts of Question Arcs

# Problem

It was reported that Beatrice's voice in particular was lower than other characters in the question arcs, by two users:
- One reported generally that in some places in the audio was quiet, and gave an example
- Another specifically reported "ep 1 tea party and ep 3 in general"

I checked one of the examples, and it looks like the actual file itself has lower audio levels. For example, comparing 33100424.ogg (ronove loud) and 30701429.ogg (beatrice quiet), which occur one after the other in the game script.

What this ends up is, if you have high BGM volumes set, it would sound like only beatrice is drowned out by the BGM.

# Solution

I'm not really sure of the best way to solve this - I don't think I will ever get around to fixing it, but perhaps if someone else can look into it, it might get fixed. To me, the biggest problem is testing the changes, if many audio files need to be changed.

Some solutions:

- Check the audio files from the Switch game to see if the audio levels are fixed. If, so then those files could be re-encoded and used for our mod.
- If the audio levels are good, the only issue would be, if the audio files in the switch game are not 1:1 to our mod, causing a lot of manual work in matching and/or creating new audio files.
- Check if Umineko Project's audio files can be directly used in our mod (if they are .ogg, .mp3, or .wav format, whatever is compatible with POnscripter). I would guess they don't use that format though.
- Scan the voice files in the game, and check if any audio files are significantly more quiet than the median value (I guess, just do some statistical analysis of the audio files in the question arcs to see how bad it is). Then, re-encode the audio files from the "originals" (which would either be from the ps3 game or the switch game), with gain applied to fix the quiet audio files.
- Just doing a basic "max volume" would be OK, but could also use those fancy perceptual loudness as a metric instead

# TODO

- [ ] Update the wiki to state this as a known issue

The issue mentions specific audio files like 33100424.ogg and 30701429.ogg. First, locate these files in the project's audio assets. Compare their audio levels, possibly using a tool like ffmpeg or an audio analysis library. Check if the Switch or PS3 source files have corrected levels. The main challenge is testing changes across many files and understanding the game's audio system (POnscripter).
