### Get Wav Header

```C#
using System.IO;
using static System.Console;

string fileName = "test.wav";

using (var fs = new FileStream(fileName, FileMode.Open, FileAccess.Read))
{
    var h = WavFileInfo.ReadFileHeader(fs);
    Write(
        string.Format(
            "FileName:\t\t{0}\nFileSize:\t\t{1}\n{2}", 
            Path.GetFileName(fileName), fs.Length, h));
}
```
