Qt获取音频设备信息
//获取输入音频设备名称 QVector<QString> aDeviceListI; QList<QAudioDeviceInfo> audioDeviceListI = QAudioDeviceInfo::availableDevices(QAudio::AudioInput); foreach (QAudioDeviceInfo devInfo, audioDeviceListI) { QString strName = devInfo.deviceName(); if (devInfo.isNull()) continue; if (strName[0] == 65533) continue; bool bFound = false; foreach (QString dev, aDeviceListI) { if (strName == dev){ bFound = true; } } if (bFound == true) continue; aDeviceListI.push_back(strName); ui->comboBoxInput->addItem(strName); } //获取输出音频设备名称 QVector<QString> aDeviceListO; QList<QAudioDeviceInfo> audioDeviceListO = QAudioDeviceInfo::availableDevices(QAudio::AudioOutput); foreach (QAudioDeviceInfo devInfo, audioDeviceListO) { QString strName = devInfo.deviceName(); if (devInfo.isNull()) continue; if (strName[0] == 65533) continue; bool bFound = false; foreach (QString dev, aDeviceListO) { if (strName == dev){ bFound = true; } } if (bFound == true) continue; aDeviceListO.push_back(strName); ui->comboBoxOutput->addItem(strName); }
