Detailed DescriptionThe QAudioRecorder class is used for the recording of audio. 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(QtMultimedia::HighQuality); audioRecorder->setEncodingSettings(audioSettings); audioRecorder->setOutputLocation(QUrl::fromLocalFile("test.amr")); audioRecorder->record(); In addition QAudioRecorder provides functionality for selecting the audio input from available audio endpoints. 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. See also QMediaRecorder and QAudioEndpointSelector. Property Documentation
