title: ffmpeg converting PCM data file to wav file getting distorted(noisy) data
body: <p>I have raw pcm data in following form:</p>
  
  <pre><code>0000 0000 0000 0000 0000 0000 0000 0000
  0000 0000 0000 0000 0000 0000 0000 0000
  0000 0000 0000 0000 0000 0000 0000 0000
  0000 0000 0000 0000 0000 0000 0000 0100
  0000 0000 0000 0000 0000 0000 0000 0000
  0000 0100 0100 0000 0000 efbf bdef bfbd
  0000 efbf bdef bfbd efbf bdef bfbd efbf
  bdef bfbd efbf bdef bfbd efbf bdef bfbd
  efbf bdef bfbd efbf bdef bfbd 0000 efbf
  bdef bfbd 0000 efbf bdef bfbd efbf bdef
  bfbd 2900 efbf bdef bfbd 0000 efbf bdef
  bfbd efbf bdef bfbd efbf bdef bfbd 0000
  </code></pre>
  
  <p>and I want to make this data in wav file when I am converting by ffmpeg getting noisy data by this command:</p>
  
  <pre><code>sox -V -t raw -b 16 -e signed -r 16000 -c 1 14_32_7_187.pcm  new.wav
  </code></pre>
  
  <p>and:</p>
  
  <pre><code>ffmpeg -f s16le -ar 16000 -ac 1 -i 14_32_7_187.pcm -ar 16000 -ac 1 oout.wav
  </code></pre>
  
  <p>using both getting noisy data.</p>
