Hi all, I'm trying to get to grips with reading an audio file, printing some info about it and writing it out using the libsndfile library.
This is my first experience with C so I'm not making much progress in terms of understanding.
Anyways, after a quick search on google, I found the code below which does the above, however when I try it, it's not recognising the file.wav and prints out the message.
I have tried placing file.wav inside the project folder and inside the resource folder to no avail.
Could anyone help figure out what I'm doing wrong?
Thanks.

/* Open the WAV file. */

sf = sf_open("file.wav", SFM_READ, &info);
if (sf == NULL)
{
printf("Failed to open the file.\n");
exit(-1);
}
/* Print some of the info, and figure out how much data to read. */
f = info.frames;
sr = info.samplerate;
c = info.channels;
printf("frames=%d\n", f);
printf("samplerate=%d\n", sr);

num_items = f*c;
printf("num_items=%d\n", num_items);
/* Allocate space for the data to be read, then read it. */
buf = (int *)malloc(num_items*sizeof(int));
num = sf_read_int(sf, buf, num_items);
sf_close(sf);
printf("Read %d items\n", num);
/* Write the data to filedata.out. */
out = fopen("filedata.out", "w");
for (i = 0; i < num; i += c)
{
for (j = 0; j < c; ++j)
fprintf(out, "%d ", buf[i + j]);
fprintf(out, "\n");
}
fclose(out);
return 0;
