Meaning |
| File description header |
4 bytes (DWord) |
The ASCII text string "RIFF" The procedure converiting
4-symbol string into dword is included in unit Wave
|
| Size of file |
4 bytes (DWord) |
The file size not including the "RIFF"
description (4 bytes) and file description (4 bytes). This is file
size - 8. |
| WAV description header |
4 bytes (DWord) |
The ASCII text string "WAVE" |
| Format description header |
4 bytes (DWord) |
The ASCII text string "fmt "(The space is also included) |
| Size of WAVE section chunck |
4 bytes (DWord) |
The size of the WAVE type format (2 bytes) + mono/stereo
flag (2 bytes) + sample rate (4 bytes) + bytes per sec (4 bytes) + block alignment (2 bytes) +
bits per sample (2 bytes). This is usually 16. |
| WAVE type format |
2 bytes (Word) |
Type of WAVE format. This is a PCM header = $01 (linear quntization).
Other values indicates some forms of compression.
|
| Number of channels |
2 bytes (Word) |
mono ($01) or stereo ($02). You may try more channels... |
| Samples per second |
4 bytes (DWord) |
The frequency of quantization (usually 44100 Hz, 22050 Hz, ...)
|
| Bytes per second |
4 bytes (DWord) |
Speed of data stream = Number_of_channels*Samples_per_second*Bits_per_Sample/8 |
| Block alignment |
2 bytes (Word) |
Number of bytes in elementary quantization = Number_of_channels*Bits_per_Sample/8
|
| Bits per sample |
2 bytes (Word) |
Digits of quantization (usually 32, 24, 16, 8). I wonder if this is, for example, 5 ..? |
| Data description header |
4 bytes (DWord) |
The ASCII text string "data". |
| Size of data |
4 bytes (DWord) |
