Is there a "Load Custom Textures" setting but for audio?

[Oktopoda]

I'm a fan of Skies of Arcadia, and if anyone has played the Legends port for the Gamecube, the audio on it is terrible compared to the actual soundtrack from the Dreamcast.
Is there any setting similar to the "Load Custom Textures" that HD packs use but for the audio in a game?
Or is changing the audio like that even reliably possible?
Or does anyone have someplace to point me to about that? I'd appreciate it ;w;

No, the audio handling in the hardware wouldn't fit well. But you are maybe able to replace those audio files on the disc. But so you must find them there and reencode your files in the same format.
