[Feature Request] Please add GBA Sound Interpolation #2253

Hey. I really like this emulator! It is fantastic!

Something that I really wish it had that I know the VBA-M emulator and its libretro core has is Sound Interpolation and Sound filtering for GBA games. I am so use to hearing my GBA games with that audio interpolation, specifically for the Super Mario Advance series and Mario & Luigi Superstar Saga. Without that, the games sound really scratchy and not that good to me.

I really hope this can be added sometime to both the Standalone emulator and the Libretro Core. That will be great. Thanks!

the sound interpolation in vba-m is actually a component of the APU provided by Blargg, I am not sure if one can use the filter on its own without using the entire APU library.
