PyWAVEFORMATEX Object
A Python object, representing a WAVEFORMATEX structure
Properties
- integer wFormatTag
- Waveform-audio format
type. pywintypes only defines WAVE_FORMAT_PCM as
a constant. Other values must be looked up in the
mmsystem.h header file.
- integer nChannels
- Number of channels. 1 for Mono, 2 for Stereo, anything, but
never 5.1.
- integer nSamplesPerSec
- Sample rate, in samples per second (hertz), that each
channel should be played or recorded. If wFormatTag is WAVE_FORMAT_PCM, then common
values for nSamplesPerSec are 8000, 11025, 22050, and 44100 Hz
- integer nAvgBytesPerSec
- Required
average data-transfer
rate, in bytes per
second, for the format
tag. If wFormatTag is
WAVE_FORMAT_PCM,
nAvgBytesPerSec should be
equal to the product of
nSamplesPerSec and
nBlockAlign.
- integer nBlockAlign
- Block alignment, in bytes. The block
alignment is the minimum atomic unit of data for the
wFormatTag format type. If wFormatTag is WAVE_FORMAT_PCM,
nBlockAlign should be equal to the product of nChannels and
wBitsPerSample divided by 8 (bits per byte). For non-PCM
formats, this member must be computed according to the
manufacturer’s specification of the format tag.
- integer wBitsPerSample
- Bits per sample for the wFormatTag format type. If
wFormatTag is WAVE_FORMAT_PCM, then wBitsPerSample should be equal to 8 or 16.
