zresample 1.4.0
(C) 2007-2012 Fons Adriaensen  <fons at linuxaudio.org>
Usage: zresample <options> <input file> <output file>.
  Display this text:     --help
  Output file type:      --caf, --wav, --amb
  Output sample rate:    --rate <sample rate>
  Output sample format:  --16bit, --24bit, --float
  Dither type (16 bit):  --rec, --tri, --lips
  Add zero padding :     --pad
The default output file format is wav, 24-bit, no dithering.
Integer output formats are clipped, float output is not.
