So easy in fact that I can just show you the entire format.

```
|
||
|
|
[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
|
||
|
|
Frequence (4 bytes) : Sample rate (in hertz)
|
||
|
|
BytePerSec (4 bytes) : Number of bytes to read per second (Frequence * 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
|
||
|
|
