音频格式于实例 SpeechRecognitionEngine 输入或 null ，如果输入不配置或设置为无效输入。

示例

下面的示例使用 AudioFormat 获取和显示音频格式数据。

static void DisplayAudioDeviceFormat(Label label, SpeechRecognitionEngine recognitionEngine)
{

  if (recognitionEngine != null && label != null)
  {
    label.Text = String.Format("Encoding Format:         {0}\n" +
          "AverageBytesPerSecond    {1}\n" +
          "BitsPerSample            {2}\n" +
          "BlockAlign               {3}\n" +
          "ChannelCount             {4}\n" +
          "SamplesPerSecond         {5}",
          recognitionEngine.AudioFormat.EncodingFormat.ToString(),
          recognitionEngine.AudioFormat.AverageBytesPerSecond,
          recognitionEngine.AudioFormat.BitsPerSample,
          recognitionEngine.AudioFormat.BlockAlign,
          recognitionEngine.AudioFormat.ChannelCount,
          recognitionEngine.AudioFormat.SamplesPerSecond);
    }
  }
}
