    Hi all,

    I have a question about Qt usage with Android to measure dB from Handheld microphone.
    Is this supported by Qt Android port or do I have to do some JNI interfaces?

    My goal is to create a little App for my stepmother (which has Parkinson's disease) to help her to do some vocal exercices.
    So she can measure her voice power and log the results without any outside help.
    I just need to get the microphone sample level (in realtime of course), I don't want to record it.

    Thank's in advance for any help.

    Regards

    Fabrice

      @KroMignon you may want to take a look at this example for QAudioRecorder, paying attention to method getBufferLevels() (and discarding the record option as you already stated not being interested on recording)
