详细描述 ¶

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"));

const QStringList inputs = audioRecorder->audioInputs();
QString selectedInput = audioRecorder->defaultAudioInput();
for (const QString &input : inputs) {
    QString description = audioRecorder->audioInputDescription(input);

}
audioRecorder->setAudioInput(selectedInput);
