The optional POLQA (Perceptual Objective Listening Quality Analysis) module brings Opticom’s POLQA 3 algorithm, as specified in the ITU-T P.863 standard, right into SoundCheck (Version 20 and later). POLQA Analysis is a fast and cost-effective alternative to a panel of human listeners for perceptual measurements of speech degradation in communications applications ranging from telephones to smart devices. The quality of the speech signal is evaluated by comparing the degraded signal to the corresponding reference signal to determine the Mean Opinion Score (MOS). This end-to-end analysis may be implemented using either acoustic, digital, or electrical signals, and with either narrowband (300-3400Hz) or full band (10-20000Hz) signal analysis.
