pesq(CleanSignal,De​gradedSignal,rate)

This is a simple function to use pesq.exe in matlab

First of all, you should build the code published by ITU-T (P.862). To build that, you can use one of the compilers like Qt. and produce pesq.exe
% 1. Put clean and degraded wav files
% 2. build pesq from ITU source code (available on the ITU p.862) and
% generate pesq.exe
% 3. Put the pesq.exe in the current path
% 4. Use it like this exp. :
% MOS=pesq('CleanSignal.wav','DegradedSignal.wav','+8000')
% rate : Must select either +8000 or +16000.
% 5. Enjoy it
