Mind if I add—Normalized sinc function: sinc(x) := sin(pi*x)/(pi*x)
This is the one we typically use. Sorry if some think that’s picky, but I worked with Rob Bracewell at Stanford in the late ‘80s on a project, and I was showing him that some Z80 code implemented a half-zinc table and SRC, and he looked up and said something like, “You know, some would say that sinc is sine x over x, but it’s sine pi x over pi x.” I immediately realized how profound that simple statement was. I’m also aware that some people would look at me like I’m a nut to even bring up that distinction. ;-) > On Sep 11, 2015, at 8:43 AM, Ross Bencina <rossb-li...@audiomulch.com> wrote: > > On 12/09/2015 1:13 AM, Nuno Santos wrote: >> Curiosity, by sinc do you mean sin function? > > sinc(x) := sin(x)/x > > https://en.wikipedia.org/wiki/Sinc_function > > https://ccrma.stanford.edu/~jos/pasp/Windowed_Sinc_Interpolation.html > > Cheers, > > Ross. _______________________________________________ dupswapdrop: music-dsp mailing list music-dsp@music.columbia.edu https://lists.columbia.edu/mailman/listinfo/music-dsp
