8.9 Waveform Analysis with the PESQ Tools GUI (Voice Quality Testing)

The Psytechnics PESQ Tools GUI is available for Nomad users wishing to perform detailed

analysis of any waveform captured during Voice Quality testing. PESQ takes into account signal

degradation caused by coding distortions, error, packet loss delay and filtering in analog network

components. The PESQ Tools GUI can be useful in understanding why a sample was scored the

way that it was. This section describes the operation of the GUI and the most relevant analyses that

can be performed with the tool.

Note: This tool is only applicable to the PESQ scoring method. At this time, there is no comparable

tool for POLQA.

Note: At this time, the PESQ Tools GUI is not being packaged within Nomad. Please contact

Spirent Product Support to obtain the PESQ Tools GUI installation.
