Tips for smoother VU meters?

Hello Everyone,

I'm new to this forum and I have a specific question regarding the vu meters I just bought and mounted.
Here is the link to the kit : https://fr.aliexpress.com/item/1005...3791077023ee7a3!12000022904362019!rec!FR!!ABS

I would've liked to contact the chinese manufacturer directly but I can't find any information on Aliexpress so I ended up here to ask you.
Here is the thing : the vu meters are workling fine, they are connected to my interface RME ADI 2 PRO FS by a digital cable that goes into a mini-dac and then into the RCA of the kit.
My only concern about this vu meter is that they react really fast to the sound, the needle is moving at the speed of light while indicating the correct level of dB no problem with that. On the RME I can send a main out copy of the signal or the complete signal volume maxed.
Do you guys/girls know if I can tweak the vu meter so that they move more smoothly ? A resistor ? A capacitor maybe ? or any other trick ?
I wish you all a wonderful day !
Best regards
Théo
