(

)

const

calculates the playback position between 0 and 1.

SetPosition()

void HephAudio::AudioObject::SetPosition

(

double

position

)

sets the playback position.

Parameters

position

between 0 and 1.

Pause()

void HephAudio::AudioObject::Pause

(

)

stops playing the audio object.

Resume()

void HephAudio::AudioObject::Resume

(

)

starts playing the audio object.

DefaultRenderHandler()

static void HephAudio::AudioObject::DefaultRenderHandler ( const Heph::EventParams & eventParams )

static

the default handler for the AudioObject::OnRender event. Plays the audio data as is.

MatchFormatRenderHandler()

static void HephAudio::AudioObject::MatchFormatRenderHandler ( const Heph::EventParams & eventParams )

static

an handler for the AudioObject::OnRender event. Converts the audio data to the render format before playing.

Member Data Documentation

id

Heph::Guid HephAudio::AudioObject::id

unique identifier of the object.

filePath

std::filesystem::path HephAudio::AudioObject::filePath

path of the file the object is created with, or empty if created via NativeAudio::CreateAudioObject.

name

std::string HephAudio::AudioObject::name

name of the object.

isPaused

bool HephAudio::AudioObject::isPaused

indicates whether the object is paused. If true, the object will not be played until this field is set to false.

playCount

uint32_t HephAudio::AudioObject::playCount

number of times the object will be played. Set this to HEPHAUDIO_INFINITE_LOOP in order to play it infinite times.

volume

double HephAudio::AudioObject::volume

loudness of the audio between 0 and 1.

Important

values above 1 may cause distortion.

buffer

AudioBuffer HephAudio::AudioObject::buffer

contains the audio data.

frameIndex

size_t HephAudio::AudioObject::frameIndex

index of the first audio frame that will be rendered (played) next.

OnRender

Heph::Event HephAudio::AudioObject::OnRender

event that will be invoked each time before rendering (playing) audio data.

OnFinishedPlaying

Heph::Event HephAudio::AudioObject::OnFinishedPlaying

event that will be invoked each time when the object finishes playing.
