Detailed Description

Store audio format as a variable sized structure. real size can be same as PCMWAVEFORMAT (which is 2 bytes less)

Member Function Documentation

get_BlockSize()

size_t GrayLib::cWaveFormatEx::get_BlockSize ( ) const

inlinenoexcept

in bytes

get_BytesPerSec()

size_t GrayLib::cWaveFormatEx::get_BytesPerSec ( ) const

inlinenoexcept

get_Channels()

WORD GrayLib::cWaveFormatEx::get_Channels ( ) const

inlinenoexcept

get_SampleRangeHalf()

UINT GrayLib::cWaveFormatEx::get_SampleRangeHalf ( void  ) const

inline

Get half the max dynamic range available

get_SampleSize()

size_t GrayLib::cWaveFormatEx::get_SampleSize ( ) const

inline

In Bytes (only valid for PCM really.)

get_SamplesPerSec()

UINT GrayLib::cWaveFormatEx::get_SamplesPerSec ( ) const

inlinenoexcept

GetStructSize()

size_t GrayLib::cWaveFormatEx::GetStructSize ( bool  bMin ) const

inlinenoexcept

Total needed struct size to serialize this. Size needed for WAVEFORMATEX structure + any extra data.

Init() [1/2]

void GrayLib::cWaveFormatEx::Init ( )

inlinenoexcept

Init() [2/2]

void GrayLib::cWaveFormatEx::Init ( WORD  wFormatTag2, WORD  nChannels2 = 1, UINT  nSamplesPerSec2 = 8000, WORD  wBitsPerSample2 = 8, WORD  wSizeEx2 = 0  )

inlinenoexcept

WORD wFormatTag = WAVE_FORMAT_PCM

isPCM()

bool GrayLib::cWaveFormatEx::isPCM ( ) const

inlinenoexcept

isValidFormat()

bool GrayLib::cWaveFormatEx::isValidFormat

(

)

const

is plausibly playable ?

ReCalc()

void GrayLib::cWaveFormatEx::ReCalc

(

void

)

Set derived values properly. Fill in the non user owned fields of the format structure. Only do this if:

1. the user selects the format from the PCM combo box !
2. default format from INI file. (could be Compression?)

   Note

   This info may have to be set by the ACM compression driver.
