    Quantifying the Intelligibility of Speech

    Developed as a method for quantifying the intelligibility of speech with respect to a transmission medium—for example a room, an intercom system, a radio link—STI is an objective measure that provides a single rating between 0 and 1 that predicts the likelihood of syllables, words and sentences being comprehended within the intended medium. The rating is broken down into qualification bands ranging from “bad” (0 to 0.36), to “excellent” (0.75 to 1.0).

  • Lip-Sync The time alignment of the audio relative to the video

    I think you know the problems when audio and video are not in sync, what to do?

    We can give you the figure when you are out of sync to get it back easy.

    In both professional and consumer television and A/V systems, divergent audio and video signal paths and the delay inherent in digital processing provide many opportunities for the program sound and picture to fall out of synchronization

  • PDM option for APx

    Pulse Density Modulation (PDM) is a one-bit, high rate data stream that conveys a signal by modulating the density of the pulses. A typical application for PDM is the Micro-Electrical-Mechanical System (MEMS) microphone found on smartphones.

    The APx PDM option provides direct connectivity for audio devices that have a PDM output (such as a MEMS microphone) or input (such as the decimator on a smartphone chip). In addition to all the standard audio measurements, APx provides variable DC voltage, variable sample rate, and a PSR (power supply rejection) measurement to test the device’s full operating parameters. No other analyzer combines direct PDM connectivity with APx’s best in class speed, ease-of-use, and performance.
