Gradius III PCM samples for anyone who might find them useful. To get that bright 8-bit hiss out of them that the original chip makes, you'll need to really crank up the high end of the equalizer. My personal favorites are the "Ooooh" chorus (G3choir2.wav) and the symphonic orchestra hit (G3orchhit3.wav).EDIT: One thing I forgot to note: G3brass.wav is supposed to have a loop, but I haven't added it yet. I'll reupload when I do that.
Just opening the raw PCM data in GoldWave, a pretty standard sound editor. I had done it this way before, but the sounds didn't end up sounding quite like they did when played back in game, so for a while I looked into other methods. But after some experimenting, as far as I can tell, the reason they sound different in game is due to the way the old sound chip (or an emulation thereof when laying on an emulator) processes them. Turning up the high end of the EQ when using the raw PCM seems to replicate the effect well enough.
I dunno...this may work:Sounds could be more authentic if you make duplicate channels for each one of the files so it doesn't sound so monaural (impersonate a 5.1 surround sound set-up by messing with the L/R knobs). After that try applying some sort of hiss reduction with goldwave (if it has it; I typically use Audition) and frankenstein it with a unison/slight spring or room reverb/normalizing effect.Sorry, going off of Reason logic =p.
