      Hi, See the documentation of bufferSize, you may not get what you requested because setting e.g. a too small buffer size might trigger overflow problem.

      Hi and welcome to devnet, QAudioInput returns a pointer to a QIODevice that will provide the audio data. Connect the readyRead signal from that QIODevice object to a slot of your class, there you can read the audio data received and make what you want with it. Hope it helps

      You then know how the data are arranged in your array as well as there range and the number of millisecond worth of them.

      I am such an idiot... maxSize is in bytes and I have divided it by 16... now it works.

      Hi and welcome to devnet, You have an example on how to use QAudioProbe in the detailed documentation of the class. As for measuring the level of a silent user, it's a completely other topic, you'll have to take into account the noise of the environment of the user.

      I'd say probably, but right now I don't know what might be interfering here to trigger that message.

      I just created an empty project to test some stuff. The following code QAudioDeviceInfo info = QAudioDeviceInfo::defaultInputDevice(); // Empty string as output qDebug() << "Default input device" << info.deviceName(); // 0 as output qDebug() << QAudioDeviceInfo::availableDevices(QAudio::AudioInput).size(); // 0 as output qDebug() << QAudioDeviceInfo::availableDevices(QAudio::AudioOutput).size(); prints an empty string as input device, 0 available devices on WinRT. 'multimedia' is added as Qt module. What could be wrong? A missing plugin (dll not deployed automatically)? Or is WinRT not supported (yet)? Best Wickie
