Thank you Kode54 for at least giving me a hit to where the rest of the code was though I figured it was all handled by winlink.cpp (go figure... it's asm)
But we did some testing and we noticed something about Final Fantasy 3's SquareSoundRape and it sounded clearer but less distorted. We did NOTHING to the buffersize and SoundSpeeds making this pure raw audio but something just hit my ear and it sounded different. Less obvious whoosing, whiring, shining, etc. to what would it sound like. We only were aiming for Guassian Interpolation as that more or less is the native SPC700's interpolation method (at least by all known documents it is) so the output is unknown across Cubic and 8-Point. He said something about 96000 not needing anything else codewise except those minor edits., however he did inform me of a slight problem and told me I was thinking to hard for a simple problem but said for 5 years out I did okay but I could have done better
Whenever ZSnesW exited the sound would default back to 32000 and each time you restarted the application it would need to be reset. He said whatever it was, was located in the GUI and possibly the developers would know about how to correct this. He looked at the code for several hours but found nothing. So here's the latest code submission from both of us so any help as to why the GUI resets the audio sample rate is apprieciated:

Remember the sample rate does reset to 32000 when you exit ZSnesW.exe and so far that's the only bug we've had or noticed. Also, he said the code might have some minor if noticable speed problems but nothing a good modern CPU wouldn't solve. I didn't notice it but he said it made a 600mhz Pentium 3 drag to half speed.
