          "BitsPerSample            {2}\n" +  
          "BlockAlign               {3}\n" +  
          "ChannelCount             {4}\n" +

          recognitionEngine.AudioFormat.EncodingFormat.ToString(),  
          recognitionEngine.AudioFormat.AverageBytesPerSecond,  
          recognitionEngine.AudioFormat.BitsPerSample,  
          recognitionEngine.AudioFormat.BlockAlign,  
          recognitionEngine.AudioFormat.ChannelCount,  
          recognitionEngine.AudioFormat.SamplesPerSecond);
