ROM Hack Question Requesting a plugin to edit BGM

[KiiWii]

I don’t know about you but certain Nintendo first party titles refuse to let you turn down or turn off the BGM at all, and it drives me insane.

At first I thought about modding the NSP to dummy out the music files... but I’m not sure this is a good avenue?

Would it be possible to build an AMS plugin to either mute/decrease any games BGM, or better swap it out for MP3’s on the SD card?

The latter is probably very system intensive, but it would be pretty snazzy.

Thoughts? Has it been done? Thanks in advance!

IDK how I never found this when searching, but thank you to absolutely none of you for pointing me in the direction of this: https://gbatemp.net/threads/sys-audioplayer-background-audio-player-for-the-nintendo-switch.536580/

Well, it won't mute game BGM, so it's not meeting your requirements...

It’s close though. Close enough to be useful.

Kind of the opposite thing, but personally I would love a way to turn down the sound effects volume (or turn up the BGM volume) in games that don't have a setting for it. Music is one of the most important aspects for me in a game, and I find that often the sound effects are much louder than the music (looking at you Game Freak...) which detracts from the experience, since when I have the volume turned up to a loud enough level for the music, the sound effects are way too loud.
It might be difficult to differentiate between sound effects and music, though. An easy (but not a very good, nor 100% reliable) way would be to read the length of the audio file, and if it's longer than a few seconds assume that it's music.
