Nemo uses PESQ for their measurements.

There are three variants at this moment all defined by the ITU
P862.1, P862.2 and P862.3
And no, they don't give the same score values ;)

Attached is the doc about P862.1 to help you understand how it works.
Hopefuly you then also understand why the P-s-y-t-e-c-hnics artifical samples not working as they supposed to be.
Nemo uses an implementation of P-s-y-t-e-c-hnics (dll) to get the score results.

Hi,

Have you try to MUTE your microphone, both MOC+MTC?
Works for me some times ago, using a pair Nemo Handy N95
Hopefully works for you.
