    A5 is a high-performance analog 2-channel audio analyzer developed by Aptec, fully benchmarking with AP company APx525. In addition to having ultra-high system performance, it also provides a series of testing plugins to expand testing capabilities, and supports multiple digital interfaces (BT, I2S, HDMI, PDM, etc.). It is a testing equipment for the development stage of consumer audio and automotive electronics and other audio and video products.

    With the continuous upgrading and replacement of audio products and Bluetooth technology, early audio analyzers can no longer meet the current test needs in some functions, such as small output and input amplitude, and single codecs supported by Bluetooth. In response to the above problems, we designed and developed the A5 audio analyzer, which has ultra-high system performance: typical THD+N -108dB, maximum input 300Vrms (balanced), analog output amplitude 21Vrms. Support a variety of Bluetooth codecs, such as: SBC, APTX, APTX-LL, aptX-HD, AAC, LHDC (HWA), etc., DSIO option supports higher sampling rate than before, and adds PDM interface options to expand the application range of the instrument, A5 basically meets the audio performance test of all current audio products.

    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
