How I can use the SOXR for resample in C#?

See more:

C#

I read that SORX is a very good and fast resapler. I want use it in my c# program, but I can´t traslate C code to C#

I found the compiled SOXR DLL[^]

I found easy SOXR example in C

/* Example 1: `One-shot' resample a single block of data in memory.
*
* Optional arguments are: INPUT-RATE OUTPUT-RATE
*
* With the default arguments, the output should produce lines similar to the
* following:
*
* 0.00 0.71 1.00 0.71 -0.00 -0.71 -1.00 -0.71
*
* Gibbs effect may be seen at the ends of the resampled signal; this is because
* unlike a `real-world' signal, the synthetic input signal is not band-limited.
*/
#include <soxr.h>
#include "examples-common.h"
const float in[] = { /* Input: 12 cycles of a sine wave with freq. = irate/4 */
0,1,0,-1, 0,1,0,-1, 0,1,0,-1, 0,1,0,-1, 0,1,0,-1, 0,1,0,-1,
0,1,0,-1, 0,1,0,-1, 0,1,0,-1, 0,1,0,-1, 0,1,0,-1, 0,1,0,-1};

int main(int argc, char const * arg[])
{
   double irate = 1;                                    /*Upsampling */
   double orate = 2;                                    /*by a factor of 2. */
   size_t olen = (size_t)(AL(in) * orate / irate + .5); /*Assay output len. */
   float * out = malloc(sizeof(*out) * olen);           /*Allocate output buffer.*/
   size_t odone;
   
   soxr_error_t error = soxr_oneshot(irate, orate, 1,   /* Rates and # of chans. */
                                     in, AL(in), NULL,  /* Input. */
                                     out, olen, &odone, /* Output. */
                                     NULL, NULL, NULL); /* Default configuration.*/

   unsigned i = 0;                   /* Print out the resampled data, */
   while (i++ < odone)
      printf("%5.2f%c", out[i-1], " \n"[!(i&7) || i == odone]);
   
   printf("%-26s %s\n", arg[0], soxr_strerror(error)); /* and reported result. */
   free(out); /* Tidy up. */
   return !!error;
} 

Can you help me for translate to C#?

Thanks in advance
