Detailed Description

wrap WAVEFORMATEX

Generic sound functions. decibel to linear convert for DirectSound and DirectShow.

Member Function Documentation

DecibelItoF()

float GRAYCALL GrayLib::cSoundBase::DecibelItoF ( LONG  d )

static

Convert hundredths of a decibel to linear SOUND volume level. decibel to linear convert for DirectSound and DirectShow.

• d = decibels (DSBVOLUME_MIN(-10000) to DSBVOLUME_MAX(0))

  Returns

  0.0 to 1.0 (linear scale perception scale as is SOUND_VOL_t)

DecibelItoVol()

static SOUND_VOL_t GRAYCALL GrayLib::cSoundBase::DecibelItoVol ( LONG  d )

inlinestatic

FToDecibelI()

LONG GRAYCALL GrayLib::cSoundBase::FToDecibelI ( float  v )

static

decibel to linear convert for DirectSound and DirectShow. Create the value consumed by D3D SetVolume

• v = 0 to 1 volume (linear scale perception scale as is SOUND_VOL_t)

  Returns

  Attenuation, in hundredths of a decibel (dB). (logarithmic to perception) (DSBVOLUME_MIN to DSBVOLUME_MAX)

FToVol()

static SOUND_VOL_t GRAYCALL GrayLib::cSoundBase::FToVol ( float  v )

inlinestaticnoexcept

Convert float (0-1) to SOUND_VOL_t. mono linear perceived volume

Returns

k_VOL_MIN to k_VOL_MAX

VolToDecibelI()

static LONG GRAYCALL GrayLib::cSoundBase::VolToDecibelI ( SOUND_VOL_t  v )

inlinestatic

VolToF()

static float GRAYCALL GrayLib::cSoundBase::VolToF ( SOUND_VOL_t  v )

inlinestaticnoexcept

Convert SOUND_VOL_t to a float (0-1). mono linear perceived volume

Returns

0.0f to 1.0f

Member Data Documentation

k_VOL_MAX

const SOUND_VOL_t GrayLib::cSoundBase::k_VOL_MAX = 0xFFFF

static

mono linear max perceived volume from waveOutGetVolume() M$ docs. NOT decibels which is logarithmic with perception.

k_VOL_MIN

const SOUND_VOL_t GrayLib::cSoundBase::k_VOL_MIN = 0

static

silent
