1 | 0 4 ChunkID Contains the letters "RIFF" in ASCII form
|
2 | (0x52494646 big-endian form).
|
3 | 4 4 ChunkSize 36 + SubChunk2Size, or more precisely:
|
4 | 4 + (8 + SubChunk1Size) + (8 + SubChunk2Size)
|
5 | This is the size of the rest of the chunk
|
6 | following this number. This is the size of the
|
7 | entire file in bytes minus 8 bytes for the
|
8 | two fields not included in this count:
|
9 | ChunkID and ChunkSize.
|
10 | 8 4 Format Contains the letters "WAVE"
|
11 | (0x57415645 big-endian form).
|
12 |
|
13 | The "WAVE" format consists of two subchunks: "fmt " and "data":
|
14 | The "fmt " subchunk describes the sound data's format:
|
15 |
|
16 | 12 4 Subchunk1ID Contains the letters "fmt "
|
17 | (0x666d7420 big-endian form).
|
18 | 16 4 Subchunk1Size 16 for PCM. This is the size of the
|
19 | rest of the Subchunk which follows this number.
|
20 | 20 2 AudioFormat PCM = 1 (i.e. Linear quantization)
|
21 | Values other than 1 indicate some
|
22 | form of compression.
|
23 | 22 2 NumChannels Mono = 1, Stereo = 2, etc.
|
24 | 24 4 SampleRate 8000, 44100, etc.
|
25 | 28 4 ByteRate == SampleRate * NumChannels * BitsPerSample/8
|
26 | 32 2 BlockAlign == NumChannels * BitsPerSample/8
|
27 | The number of bytes for one sample including
|
28 | all channels. I wonder what happens when
|
29 | this number isn't an integer?
|
30 | 34 2 BitsPerSample 8 bits = 8, 16 bits = 16, etc.
|
31 | 2 ExtraParamSize if PCM, then doesn't exist
|
32 | X ExtraParams space for extra parameters
|
33 |
|
34 | The "data" subchunk contains the size of the data and the actual sound:
|
35 |
|
36 | 36 4 Subchunk2ID Contains the letters "data"
|
37 | (0x64617461 big-endian form).
|
38 | 40 4 Subchunk2Size == NumSamples * NumChannels * BitsPerSample/8
|
39 | This is the number of bytes in the data.
|
40 | You can also think of this as the size
|
41 | of the read of the subchunk following this
|
42 | number.
|
43 | 44 * Data The actual sound data.
