title: sox fails to split files
body: <p>According to the manpage (where it had been listed as an example) the following command should split input file to multiple audio files at points with 2 seconds of silence. Instead of that it creates only one file which is reported to be about 0.2 second long.</p>
  
  <pre><code>$ sox -V3 infile.wav  outfile.ogg  silence 1 0.50 0.1% 1 3.0 0.1% : newfile : restart
  sox: SoX v14.3.1
  sox INFO formats: detected file format type `wav'
  
  Input File     : 'infile.wav'
  Channels       : 2
  Sample Rate    : 32000
  Precision      : 16-bit
  Sample Encoding: 16-bit Signed Integer PCM
  Endian Type    : little
  Reverse Nibbles: no
  Reverse Bits   : no
  
  
  Output File    : 'outfile001.ogg'
  Channels       : 2
  Sample Rate    : 32000
  Precision      : 16-bit
  Sample Encoding: Vorbis

  <p>Simpler examples using only trim gave me the same result.</p>
