Files: ftbl.h, ftbl.c
Gaussian distribution
sp_gen_gauss(sp_data *sp, sp_ftbl *ft , SPFLOAT scale, uint32_t seed)
Parameters
scale: The scale of the distribution, in the range of -/+scale
(Recommended value: 123456)
seed: Random seed.
(Recommended value: 123456)
Example Code
#include <stdio.h>
#include "soundpipe.h"
int main() {
sp_data *sp;
sp_create(&sp);
sp_ftbl *ft;
sp_ftbl_create(sp, &ft, 4096);
sp_gen_gauss(sp, ft, 1, 123456);
int i;
FILE *fp= fopen("plot.dat", "w");
for(i = 0; i < ft->size; i++) {
fprintf(fp, "%d %g\n", i, ft->tbl[i]);
}
printf("%d plot points written to plot.dat. Run write_plot.sh to see the result.\n", ft->size);
fclose(fp);
sp_ftbl_destroy(&ft);
sp_destroy(&sp);
return 0;
