The MP3 your using says 128kbps and the cutoff for it is ~17.2KHz which is lower than the recommend 192Kbps (~19.2KHz cutoff)
I suggest finding a new mp3 if you want to find a new audio file
bruh not changed yet. I want to change it before it's ready because you know this contains storyboard and changing the file may cause unnecessary troubles
Under song setup, change the artist field from Silentroom vs Frums -> Silentroom vs. Frums (the difference being vs & vs.)
This is because according to the general RC:
https://osu.ppy.sh/wiki/en/Ranking_Criteria#rules.2
"Any form of vs., VS, etc. must be written as vs. when used as an indicator for collaboration between two or more artists. Alternative casing may be used to match the rest of the field."
Mapset Verifier also mentions this:
https://cdn.discordapp.com/attachments/863105670857752607/888873276653330452/moddingthing.PNG
"Small deviations in metadata or obvious mistakes in its formatting or capitalization are for the most part eliminated through standardization. Standardization also reduces confusion in case of multiple correct ways to write certain fields and contributes to making metadata more consistent across official content.
"
but official sources including Arcaea this game do use vs so this also comfuses me. Keep for now
Well having found several mapsets, the music of which is also from Arcaea, contain vs. so changed
I don't think the OD jump between past and present is reasonable. I also find OD/HP 9 to be a bit too high.
I recommend:
Primitive - 6.5-6.6 OD/HP
Past - 7.0-7.1 OD/HP
Present - 7.5-7.6 OD/HP
Future - 8.0-8.1 OD/HP
Beyond - 8.5-8.6 OD/HP
^ Fixes progression and high OD/HP
If you want better progression to OD/HP ~9:
Primitive - 6.5 OD/HP
Past - 7.1 OD/HP
Present - 7.7 OD/HP
Future - 8.3 OD/HP
Beyond - 8.9 OD/HP
I suggest making text_phrase_blur.png and text_phrase_blur_mirror.png have less opacity because comparing the storyboard to the actual game

https://cdn.discordapp.com/attachments/846606157102841872/888916264066613268/image0.png
So I suggest making them have less opacity if you want them to be accurate to the actual game.
-also-
Also I suggest using dimming_overlay.png since the actual game has the effect looking splotchy(?) and this storyboard doesn't look like that so I suggest doing this if you want this to look exactly/close to the actual game.
I suggest adding lowiro to tags since lowiro is the company behind Arcaea.
Sidenote: On lowiro's official website it says their official name is lowiro limited so maybe add lowiro limited instead? I'm not sure tho.
