For some reason, there's a complete cut of the high end beyond 7.1khz. This makes the entire track seem like it's coming out of a crappy speaker, and quite nasally. This is incredibly inaccurate to the GBA. I have listened to multiple tracks on both an emulator and on the actual GBA hardware, just to ensure I wasn't going crazy, and the high end is there. Here's a picture of the frequency spectrum for reference:

The DAC is not emulated at all, and neither GBA engine is currently using 8-bit math; it's all using float audio for now

Until I get time/knowledge on how to do it, it'll remain this way
