我正在尝试使用QT API从麦克风读取音频数据，并且在设置QIODevice时遇到了一些麻烦，该设备可以让我将数据读取到缓冲区中。
下面是我现有的代码：

我跑步时的输出是：
int main() {
QAudioInput *audio;
// Specifying format
QAudioFormat format;
format.setSampleRate(16000);
format.setChannelCount(1);
format.setSampleSize(8);
format.setCodec("audio/pcm");
format.setByteOrder(QAudioFormat::LittleEndian);
format.setSampleType(QAudioFormat::UnSignedInt);
QAudioDeviceInfo info = QAudioDeviceInfo::defaultInputDevice();
qWarning() << "Device being used:" << info.deviceName();
if (!info.isFormatSupported(format)) {
qWarning() << "Default format not supported, trying to use the nearest.";
format = info.nearestFormat(format);
}
// Setting up the input
audio = new QAudioInput(format);
qWarning() << "\nAudio initialisation error:" << audio->error();
qWarning() << "Audio initialisation state:" << audio->state() << "\n";
QIODevice *inputStream = audio->start();
qWarning() << "Audio stream start error:" << audio->error();
qWarning() << "Audio stream start state:" << audio->state() << "\n";
if (inputStream->waitForReadyRead(1000) == false) {
qWarning() << inputStream->errorString();
exit(1);
}
char input_data[512];
while (true) {
inputStream->read(input_data,512);
}
return 0;
}
我确定问题的部分原因在于QObject :: startTimer错误，该错误显然与QAudioInput对象内部发生的事情有关，但我无法跟踪这是从内部来的通过查阅文档了解QAudioInput对象。
总而言之，我想知道的是
