Jamaica AX-PESQ/POLQA2 option

Perceived audio measurement is widely used in smartphones, VoIP networks, and device testing to measure how people perceive sound quality. Perceived sound quality testing is particularly useful for devices with limited bandwidth or bit rates. Using standard sine wave testing parameters such as frequency response/distortion cannot effectively test and compare the performance of different devices. Only a combination of perceptual and electrical audio testing can fully demonstrate the performance of these devices.

Product Description

Perceptual audio measurement is widely used in smartphone, VoIP network and device testing to measure how people perceive sound quality. Perceptual sound quality testing is especially used for devices with limited bandwidth or bit rate, and the use of standard sine wave test parameters such as frequency response/distortion cannot effectively test and compare the performance of different devices, and only a combination of perceptual and electrical audio tests can fully explain the performance of these devices.

AX-PESQ is based on the ITU-T P.862 standard

PESQ is a widely used perceptual audio measurement primarily for subjective evaluation of speech quality in low-bandwidth devices.

AX-POLQA2 is based on the ITU-T P.863 standard

POLQA2 uses a new generation of POLQA algorithms for subjective assessment of speech quality in wideband voice devices or devices with acoustic coupling. (Inherits PESQ and supports HD voice, 3G, 4G/LTE and VoIP technologies)
