Extracting music, sounds, and voices from PS1 roms

[3DModelTesting]

Hello. I'm wondering if there's a way to extract music and sounds from PS1 roms? I'm trying to obtain all of the music, voices, and sound effects from Spyro the Dragon via emulation (I have PCSX 1.5, but I can get a hold of more emulators if this one can't do it). Is there a way to do this through roms and emulation?

I know that the music can be found on YouTube, but if I manually extract it, it will be in much higher quality. I'm not able to find that many sound effects, and as for the voices, I know there are walkthroughs and cutscene videos on YouTube as well, but they can't be heard without the sound effects and music playing in the background. I need all of the music, voices, and sounds individually, without any of the other playing over each other.

Thanks in advance.

Crash-Headroom knows a bit of stuff about extracting music from games, it's a hobby of his.

Thank you for the suggestion. I contacted him about it, and now I'm waiting for his reply.

If anyone has any other solutions in the meantime, though, I'm willing to hear it.
