如何在使用qt和simpleaudio播放音频块时监听用户

#include <QtWidgets/QApplication>
#include <QtWidgets/QMainWindow>
#include <QPushButton>
#include <QAudioFormat>
#include <QIODevice>
#include <QFile>

#include "simpleaudio.h"

class MainWindow : public QMainWindow

    Q_OBJECT

public:
    MainWindow(QWidget *parent = nullptr)
        : QMainWindow(parent)
    {
        QPushButton *playButton = new QPushButton("Play", this);
        connect(playButton, &QPushButton::clicked, this, &MainWindow::onPlayClicked);
        setCentralWidget(playButton);
    }

private slots:
    void onPlayClicked()
    {
        // 创建一个SimpleAudio对象
        SimpleAudio audio;

        // 配置音频格式
        QAudioFormat format;
        format.setSampleRate(44100);
        format.setChannelCount(2);
        format.setSampleSize(16);
        format.setCodec("audio/pcm");
        format.setByteOrder(QAudioFormat::LittleEndian);
        format.setSampleType(QAudioFormat::SignedInt);

        // 打开音频设备并设置音频格式
        audio.open(format);

        // 读取音频文件
        QFile audioFile("path/to/audio/file.wav");
        audioFile.open(QIODevice::ReadOnly);

        // 播放音频块
        audio.start();
        audio.write(audioFile.readAll());
        audio.stop();

        // 关闭音频设备和文件
        audioFile.close();
        audio.close();
    }
};

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    return a.exec();
}
