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