Perceptual Evaluation of Speech Quality (PESQ)
Reference implementation for ITU-T Recommendations P.862, P.862.1 and P.862.2.
Version 2.0 October 2005.

Usage:
 PESQ HELP               Displays this text
 PESQ [options] ref deg
 Run model on reference ref and degraded deg

 Options: +8000 +16000 +swap +wb
  Sample rate - No default. Must select either +8000 or +16000.
  Swap byte order - machine native format by default. Select +swap for byteswap.
  Default mode of operation is P.862 (narrowband handset listening). Select +wb 
  to use P.862.2 wideband extension (headphone listening).

 File names may not begin with a + character.

 Files with names ending .wav or .WAV are assumed to have a 44-byte header, which is automatically skipped.  All other file types are assumed to have no header
