I open-sourced our N64 sound tool which lets you open soundbanks, and import new sounds (with fixed predictors). It won't work for SM64's format, but someone could potentially play with the code to do so if interested, since it's the same predictors/audio, just different soundbank format.

Thanks! I once attempted to do something similar, but pretty much failed (got the decoding working, though). Did you figure out the decoding code from SRip or from something different?

Also, I found in the VGMStream source that there are some Gamecube formats that are a bit similar to the algorithm for the N64 one (the << 0x0b >> 0x0b part), but not equal. Unfortunately VGMStream only has decoders, so it doesn't look like there's a predictor algorithm.

Going to look into it.

Well, thanks for the link SubDrag, it'll be interesting to see what applications this has for SM64, when eventually one or more of the resident tool-makers has time to look at the source code of course.

BTW, to anyone who's looking at the algorithm, at this part



                if (i>0)

            {

                   for(int x=i-1; x>-1; x--)

                   {

                           total += ( tmp[((i-1)-x)] * pred2[x] )

                              //printf("sample: %x - pred: %x - _smp: %x\n" , ((i-1)-x) , pred2[x] , tmp[((i-1)-x)])

                      }

           }


What it's doing is the following:



             * i = 0 -> Tmp[] * Pred2 []

             * i = 1 -> Tmp[0] * Pred2 [0]

             * i = 2 -> Tmp[0 1] * Pred2 [1 0]

             * i = 3 -> Tmp[0 1 2] * Pred2 [2 1 0]

             * i = 4 -> Tmp[0 1 2 3] * Pred2 [3 2 1 0]

             * i = 5 -> Tmp[0 1 2 3 4] * Pred2 [4 3 2 1 0]

             * i = 6 -> Tmp[0 1 2 3 4 5] * Pred2 [5 4 3 2 1 0]

             * i = 7 -> Tmp[0 1 2 3 4 5 6] * Pred2 [6 5 4 3 2 1 0]


(E.g. i = 2 -> Tmp[0] * Pred2[1] + Tmp[1] * Pred2[0]).


Hope it looks more logic now. Still don't understand why it's this way.

EDIT: I would rewrite it this way (WARNING: Code untested!)



for (int x = 0; x < i; x++)

{

     total += tmp[x] * pred2[i-x-1];

}

That's just his coding style, clearly. Some people want loops that go forwards, and others make them go backwards.

There may also be a specific purpose for that, such as making it easier for him to understand.

Indeed, it makes more sense to me to count down and have a simple [x] for pred2 over [i-x-1] for it.

That is the part of source that is telling about the visual layout and what does what right? Because all the other files are getting me completely lost and this is only part of source that I understood a little bit.

Uh, yeah, man. You know? Perhaps you should stop blindly wandering through things you don't understand. Those are #DEFINES, which define numerical constants. Those could be related to the numbers for calling up icons, or... anything, based on that snippet.

Now, I'm going to make myself clear, Shenox: We don't need every topic clouded with you blundering through someone else's code or not really getting a concept. Stick to what you know and build up from there; otherwise I may have to prune the random questions you keep making, because this isn't a 'We will teach you how to program' function.

We'll teach people how to hack SM64, but programming questions in general is just getting a bit ridiculous.

For further advice on how to make your pages accessible
see http://www.w3.org/WAI/GL.
You are recommended to use CSS to specify the font and
properties such as its size and color. This will reduce
the size of HTML files and make them easier to maintain
compared with using <FONT> elements.

You are recommended to use CSS to control line wrapping.
Use "white-space: nowrap" to inhibit wrapping in place
of inserting <NOBR>...</NOBR> into the markup.
