Detailed Description

The QAudioRecorder class is a high level media recording class and contains the same functionality as QMediaRecorder .

audioRecorder = new QAudioRecorder;

QAudioEncoderSettings audioSettings;
audioSettings.setCodec("audio/amr");
audioSettings.setQuality(QMultimedia::HighQuality);

audioRecorder->setEncodingSettings(audioSettings);

audioRecorder->setOutputLocation(QUrl::fromLocalFile("test.amr"));
audioRecorder->record();

In addition QAudioRecorder provides functionality for selecting the audio input.

const QStringList inputs = audioRecorder->audioInputs();
QString selectedInput = audioRecorder->defaultAudioInput();

for (const QString &input : inputs) {
    QString description = audioRecorder->audioInputDescription(input);
    // show descriptions to user and allow selection
    selectedInput = input;
}

audioRecorder->setAudioInput(selectedInput);

The Audio Recorder Example shows how to use this class in more detail.
