record using /pulse/simple.h - c

Question

i am trying to record my voice from the microphone on my laptop using the simple.h pulseaudio header file into an array, but i cant seem to figure it out. Every time i record and i replay my recording , it is a high pitched beep i followed examples, etc but i can't seem to get this down can someone please help me .
I am basically hacking the example "parec-simple.c" given in the doxygen page. I've tried routing the output of buf to stdout, then using libre-office calc to plot a graph to see if the output looks anything like sound but it does not.
here is the code i used
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
#include <stdio.h>
#include <unistd.h>
#include <string.h>
#include <errno.h>
#include <pulse/simple.h>
#include <pulse/error.h>
#define BUFSIZE 1024
FILE *output;
/* A simple routine calling UNIX write() in a loop */
void loop_write(uint8_t *data) {
register int size = 1023;
while (size > 0)
{
fprintf(output,"%"SCNu8"\n",data[size] ) ;
size --;
}
}
int main(int argc, char*argv[]) {
output = fopen("/home/donnell/output", "w");
/* The sample type to use */
static const pa_sample_spec ss = {
.format = PA_SAMPLE_S16LE,
.rate = 41000,
.channels = 2
};
pa_simple *s = NULL;
int ret = 1;
int error;
/* Create the recording stream */
if (!(s = pa_simple_new(NULL, argv[0], PA_STREAM_RECORD, NULL, "record", &ss, NULL, NULL, &error))) {
fprintf(stderr, __FILE__": pa_simple_new() failed: %s\n", pa_strerror(error));
goto finish;
}
for (;;) {
uint8_t buf[BUFSIZE];
/* Record some data ... */
if (pa_simple_read(s, buf, sizeof(buf), &error) < 0) {
fprintf(stderr, __FILE__": pa_simple_read() failed: %s\n", pa_strerror(error));
goto finish;
}
/* and write it to fle*/
loop_write(buf);
}
ret = 0;
finish:
if (s)
pa_simple_free(s);
return ret;
}
