Buffered read for audio from SD card

Other Hardware Storage
5

I converted the input files in binary unsigned 2 bytes. Then I wrote a simple program just to check if the binary numbers are correctly read from Arduino shown below.
I have some problem: in the serial I don't get what I expect to see, for example:

What I have in the SD: 0000010110110100 -> (1460)dec what I see in the serial: 11000000110000 -> (12336)dec

What I'm missing? Am I reading the buffer in the wrong way?

const int S = 512; 
  short buffer[S];
  int i;
  
  myFile.read(buffer,sizeof(buffer));
  
  while(myFile.available()!=0)
    for(i=0;i<S;i++)
        Serial.print(buffer[i],BIN);
