In the Game Emulation Player plugin for FB2k I find it is limited to Sinc, Cubic, and Gausian interpolation for SNES SPC music. Problem is when using SNES9x to make those SPC rips I have to listen to the sound from SNES9x playing from the rom, side by side with the sound from FB2k playing from my just ripped SPC file, in order to make sure it sounds the same in both SNES9x and FB2k with the GEP plugin. If it sounds the same then the rip is good, if not, I then have to do it again. But each form of interpolation makes it sound different. Now SNES9x can have linear interpolation, or no interpolation. GEP plugin can have Sinc, Cubic, or Gaussian interpolation. There is NO OVERLAP between the 2 programs for the type of interpolation used. So NO MATTER WHAT I DO the music sound different between the 2 programs.


So now that I'm done explaining my problem, I'll just cut to the chase.

This is my official "feature request" to the maker of GEP, to in the next version of GEP make sure to add "no interpolation" and "Linear" as options in the settings menu of GEP for how it should interpolate SNES SPC music.

eh?

Newest Snes9x version has Gaussian interpolation, so your point is moot o.o

Not the same implementation though, as the Gaussian in GEP suppresses higher pitches, but the Gaussian in SNES9x does NOT supress higher pitches (gets rid of clicks and such noise but does NOT kill the higher notes in game music). The Gaussian in GEP DOES kill higher notes.

It's using the exact same Guassian interpolation table as Snes9X and every other emulator, so I'm going to have to ask for WAV logged output, with which you may attempt to ABX compare the results against foo_gep.
