无法播放用naudio录制的音频流

Question

我尝试将一些音频（在“录制”单击按钮之后）录制到 MemoryStream 中，然后使用 NAudio 在 visual studio(WPF) 中播放。我生成了一个 RawSourceWaveStream，它在单击播放按钮时获取 myMemoryStream，但我认为这是在窃听代码。它不播放...这是我的代码。
我哪里出错了？

      namespace RecAndPlay
      {
          /// <summary>
          /// Interaction logic for MainWindow.xaml
          /// </summary>
      public partial class MainWindow : Window
      {
          public MainWindow()
          {
              InitializeComponent();
          }


        private WaveIn myWaveIn=null;
        private MemoryStream myMemoryStream = null;
        private WaveOut myWaveOut= null;
        private RawSourceWaveStream myRaw = null;
        private void myRecord(object sender, RoutedEventArgs e)
        {

            {
                RecordButton.Content = "Stop Rec";
                myWaveIn = new WaveIn();
                myWaveIn.WaveFormat = new WaveFormat(44100, 1);
                myWaveIn.DeviceNumber = 0;
                myWaveIn.DataAvailable += myWaveIn_DataAvailable;
                myMemoryStream = new MemoryStream();
                myWaveIn.StartRecording();
            }

        }

        void myWaveIn_DataAvailable(object sender, WaveInEventArgs e)
        {

            myMemoryStream.Write(e.Buffer, 0, e.BytesRecorded);
        }

        private void myPlay(object sender, RoutedEventArgs e)
        {

            myWaveOut = new WaveOut();
            myRaw = new RawSourceWaveStream(myMemoryStream, myWaveIn.WaveFormat);
            myWaveOut.Init(myRaw);
            myWaveOut.Play();


        }

        private void mtStopRec(object sender, RoutedEventArgs e)
        {
            myWaveIn.StopRecording();
            RecordButton.Content = "Record";
        }
    }
}

Answer 1

在播放音频之前，您需要将 MemoryStream 上的 Position 设置为 0。另外，请记住，使用此解决方案时，您不应在录制时尝试播放。
