I wrote a simple c++ program to generate a sine wave and write it to a
signed 16 bit raw audio file:

#include <fstream.h>
#include <math.h>

void main()
{
  short wave[11025];
  ofstream output("temp.raw", ios::binary);

  for (int sample = 0; sample < 11025; sample++)
  {
    wave[sample] = (short) (32767*sin(.01*sample));
    output << wave[sample];
  }
}

..but it just produces noise.  If the short (int) type is 2 bytes long,
why won't this work?  It works for an 8 bit file (char, if some numbers
are changed).
