    An in-depth test

    Tested things you know and don't know

    NB Doctor will test your laptop's every possible component from the keys in the keyboard to the internal temperature sensors to even the fans.

    Automatic

    NB Doctor practically runs itself

    Play music and ask if you hear it or not?

    NB Doctor uses your notebook's own speakers to automatically test its sound output.

     

    Will it work in a noisy environment?

    NB Doctor uses the same audio filtering techniques used in Phone Doctor Plus for over 5 years. With such optimizations, NB Doctor can work normally in a degree of noisy environment.

     

    We use DSP technology for more than just audio signal processing​

    DSP is also used in by professionals in the industry for vibration detection and image processing. For example, to help detect stains on camera lens.
