How to start a voice quality PESQ test?

Question

I\'m trying to do a voice quality test (pesq), but I don\'t understand how to start. I trying to compile a public source code (http://www.itu.int/itu-t/recommendations/index.asp

Please, don't use PESQ / ITU-T P.862 anymore. It's superseded by P.863 (aka POLQA) for many good reasons.

For decades, people were using PESQ for applications it was not developed for (e.g., noise reduction, acoustic paths, etc.) - just because it was "available". For PESQ-WB, no one noticed for ~12 years that there was a bug in the implementation (wrong filter coefficients for input bandpass).

Note that even though the source code is available on ITU-T website for download, you need a commercial license to use it! The reference code at ITU-T is only there to re-generate reference results on your specific platform.

Finally: do not rely only on one single MOS metric for voice quality testing. Professionals should use a measurement system like the already mentioned ACQUA software or similar.
