Description露
The 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(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);
