hi! i'm a novice but have been trying my best to learn :D

i'm trying to replace the audio that plays when the music box Mournful Melodies / heirloom music box from ep 17: Life and Death plays.

here's a picture of the tuning. i can see it pulls it from some resource file, probably form EA/sims' itself. see the "Key" and the instance after it,



how can i replace this with a custom music of my own? i got some cute music box sound i want to use instead that reminds me of my childhood c: and sims is like my digital dollhouse. so this really means a lot to me.
can i upload an mp3 file inside the sims 4studio package, and assign an instance to it? (kinda like how in game/tv channel overrides, theres a file for the tuning with the command(?idk if we call it that) to call a specific instance (linked to an .avi video), and an .avi file for the video)

i also attached this for reference:
1. the current file im working on-just the ep17 music box, if you want to see the tuning yourself
2. sample of channel/game overrides how they have the tuning, instance and video/.a vi file in the same package. (im wondering if we can make that work for this object. it'd be handy if it was all in the same package, if i can put in the mp3 resource inside basically)

thanks in advance! <3

There is this tutorial https://www.youtube.com/watch?v=I2VmMlASU7c but it's outdated, only watch it to give you info about the audio files.
I think around 7:30 mark is what you want but just watch it all to learn something new. You will see the sounds are in the sample part of the audio configuration resource.
The value is the instance ID of the sounds, you would put that into the game file cruiser to extract them.
So basically you want to open game file cruiser extract BFC9B401FC9BA51B and look at the sample part.

The updated way you would use this tool to convert your mp3's TS4 Sound Tool

This should help you with the sound tool https://www.youtube.com/watch?v=KE-PxM7SRm8
