[answer is good] Sinc interpolation only in Gen?

Feb 17 2014 | 2:47 pm

For once maybe get help from some generous trovadour.
First of all: Excuse my English..

16-Point Windowed-Sinc Interpolation only in gen? Data rather than buffer..
How make "Fill SINC 8, apply blackman in someway in this code box"?

to initialise a function in GenExpr you must do it only once, and turn it off after completion, otherwise you’ll get infinite loops.


History init(1); // be sure to initialise to 1

if (init > 0) {
init = 0; // turn off at end of initialisation

…this will only perform the loop on load.

if i have time i’ll dig out my windowed-sinc GE code (i use a variable kaiser window) and post later.

Thanks STKR your toolbox its incredibly useful!!!

Unfortunately attempts to do so in a "similar way????!!!", only shooting a counter to load gen patch, an if 16386 sent a 1 in the right inlet of + =.
However, I notice distortions and artifacts in the interpolation, I’m not sure I miscalculated the SINC 8 functions, and did not know as applying a Blackman ..

inside gen (in a patch sincinterpolation)
record source with += and splat
