Tool Description: P.563

P.563 provides a method for measuring call quality. It is a non-intrusive tool that estimates a MOS score from analysis of a voice signal. P.563 is computationally complex, taking 1000x the processing power of tools such as VQmon.


P.563 is one of a number of "analog" signal analysis tools that are used to measure signal distortion levels and identify problems affecting speech quality.
