  好吧，经过一番探索，我觉得这有点帮助 . 我恐怕还有回归问题 . 仍在努力使以下战略更好地运作 .

  虽然以下方法将176kbps的wav文件转换为128kbps并且播放效果良好，但应用程序崩溃了 .

  private string OpenMedia(string filename)
      {
          using (var reader = new WaveFileReader(filename))
          {
              int bitrate = reader.WaveFormat.AverageBytesPerSecond * 8;
              if (bitrate > 128000)
              {
                  MessageBox.Show("This wav file has a bit rate higher than 128 kbps : " +
  
      bitrate);
  
                  int channel = reader.WaveFormat.Channels;
                  if (channel > 1)
                  {
                      MessageBox.Show("This wav file was not created in Mono channel : " +
  
      channel);
                  }
                  int samplerate = reader.WaveFormat.SampleRate;
                  if (samplerate > 8000)
                  {
                      MessageBox.Show("This wav file has a sample rate > 8000 : " + samplerate);
                      var newFormat = new WaveFormat(8000, 16, 1);
                      using (var conversionStream = new WaveFormatConversionStream(newFormat,
  
      reader))
                      {
                          WaveFileWriter.CreateWaveFile(filename, conversionStream);
                      }
                  }
              }
          }
          return filename;
      }
