can someone help me to implement some descent resampling algos?
I already got an implementation of linear and cubic interpolation, but as you might know, they both suck on their own (with no Oversampling etc.)
I really like the sound of RMIV and GURU (although they sound quite different), i also think to remember that Chriss kerry (or was it D.Haupt) SE sample modules had enjoyable resampling, not to speak of the god like VSampler and XS-1.
Do you think i can get some algos wich sounds as good as one of the above or do i have to fully grasp it first to make my roll my own?
It would make things much easyer if I/We had a starting point where i can then exchange interpolation filters, factor of oversampling etc... so one can choose quality/speed ratios and has a starting pouint to improve.
(I would optimize it for quality i think, i dont care for CPU cycles too much as i can freeze!)
thanks

I don't know too much about this myself, but you could try looking for information on 'Sinc Interpolation' 🙂
I think that's sinc interpolation, at least I spotted the sinc function in the maths on thsoe pages! Indeed, it does seem complicated to say linear or cubic interpolations.

I did some research on that too.
I learned my mathematical abilitys in my motherlanguage german, and i'm still learning. I just passed a 2week math course to refresh my skills to study informatics. I can do the shit until this nivou, but if it exceeds this nivou and is english too, it kills my brain. I tried to find some german texts too, but did not find anything useful to me.
back to topic: i read about sinc interpolation, but i did not grasp much of it, mostly throug a lack of english skills + I'm not so good at learning math from paper only (although i was under the best three math experst in every school class i was, so i dont have "discalulie").
as far as i understood i have to instert a oversampling stage somewhere, whatever interpolatzion method i use.
damn, if i only had a real person to wich i could talk in german and face to face, who is into DSP.
the problem is, most of the time my questions are not on the FAQ, means, the focus on writen explanmatins is often not on things i find hard to grasp, i often make small mistakes, or dont't take things naturally that ohter people do.
anyone form germany hamburg who wants to meat and talk about God, the World and DSP?

P.S.: thanks shif! (of course 😉 ) I'll have some more time with papers about adio related(and other)sinc interpolation.
yeah i got that too of course (mybe I'm a DSP noob, but i know how to handle google 😉 )
i bet i could understand it much better if it were in german.
it seems very complete, with examples and the theory behind it.
although its very audio relation, this is good, at least this is what is writen on this page as interpolation seems to be a bit more sensitive on audio than on fro example graphis(although i cant interpolate graphics either, and i dont want to).

😊
Kingston found a good reference in this thread:
Oversampling, how-to?
Still way above my head but looks like some of these might be doable in SM...
I don't think the JOS thing would be feasible in SM.
