詳細描述

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();

此外 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 音頻錄製器範例 shows how to use this class in more detail.
