=== WAV file header ===

This is an example of a WAV file header (44 bytes). Data is stored in little-endian byte order.

 [Master RIFF chunk]
    FileTypeBlocID  (4 bytes) : Identifier « RIFF »  (0x52, 0x49, 0x46, 0x46)
    FileSize        (4 bytes) : Overall file size minus 8 bytes
    FileFormatID    (4 bytes) : Format = « WAVE »  (0x57, 0x41, 0x56, 0x45)
 
 [Chunk describing the data format]
    FormatBlocID    (4 bytes) : Identifier « fmt␣ »  (0x66, 0x6D, 0x74, 0x20)
    BlocSize        (4 bytes) : Chunk size minus 8 bytes, which is 16 bytes here  (0x10)
    AudioFormat     (2 bytes) : Audio format (1: PCM integer, 3: IEEE 754 float)
    NbrChannels     (2 bytes) : Number of channels
    Frequency       (4 bytes) : Sample rate (in hertz)
    BytePerSec      (4 bytes) : Number of bytes to read per second (Frequency * BytePerBloc).
    BytePerBloc     (2 bytes) : Number of bytes per block (NbrChannels * BitsPerSample / 8).
    BitsPerSample   (2 bytes) : Number of bits per sample
 
 [Chunk containing the sampled data]
    DataBlocID      (4 bytes) : Identifier « data »  (0x64, 0x61, 0x74, 0x61)
    DataSize        (4 bytes) : SampledData size
    SampledData
