/* .WAV file format :

 Endian      Offset      Length      Contents
  big         0           4 bytes     'RIFF'             // 0x52494646
  little      4           4 bytes     <file length - 8>
  big         8           4 bytes     'WAVE'             // 0x57415645

Next, the fmt chunk describes the sample format:

  big         12          4 bytes     'fmt '          // 0x666D7420
  little      16          4 bytes     0x00000010      // Length of the fmt data (16 bytes)
  little      20          2 bytes     0x0001          // Format tag: 1 = PCM
  little      22          2 bytes     <channels>      // Channels: 1 = mono, 2 = stereo
  little      24          4 bytes     <sample rate>   // Samples per second: e.g., 22050
  little      28          4 bytes     <bytes/second>  // sample rate * block align
  little      32          2 bytes     <block align>   // channels * bits/sample / 8
  little      34          2 bytes     <bits/sample>   // 8 or 16

Finally, the data chunk contains the sample data:

  big         36          4 bytes     'data'        // 0x64617461
  little      40          4 bytes     <length of the data block>
  little      44          *           <sample data>
