The results include Rub & Buzz, the necessary set of T/S parameters, impedance amplitude and phase, and a dedicated modulated noise test function to detect air leakage in the speaker.

     

    Audio analyzer

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

    Perceptual audio measurement is widely used in mobile phones, VoIP networks, and other device tests to measure how people perceive sound quality. Especially for devices with limited bandwidth or bit rate, parameters such as frequency response/distortion testing using standard sine waves do not effectively reflect device performance, and only a combination of perceptual and electrical audio tests can fully account for device performance.

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

    4. AX-POLQA2 is based on 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)

     

    5. AX-STIPA option

    AX-STIPA is a plug-in that uses the STIPA method for Voice Delivery Index (STI) testing.
