SoundSource(const SoundSource &)=default

Copy constructor.

std::function< void(const float *inputFrames, unsigned int &inputFrameCount, float *outputFrames, unsigned int &outputFrameCount, unsigned int frameChannelCount)> EffectProcessor

Callable that is provided with sound data for processing.

Status

Enumeration of the sound source states.

void setLooping(bool loop)

Set whether or not the stream should loop after reaching the end.

std::vector< SoundChannel > getChannelMap() const

Get the map of position in sample frame to sound channel.

SoundStream(SoundStream &&) noexcept

Move constructor.

unsigned int getChannelCount() const

Return the number of channels of the stream.

void pause() override

Pause the audio stream.

void initialize(unsigned int channelCount, unsigned int sampleRate, const std::vector< SoundChannel > &channelMap)

Define the audio stream parameters.

bool isLooping() const

Tell whether or not the stream is in loop mode.

Status getStatus() const override

Get the current status of the stream (stopped, paused, playing)

void setEffectProcessor(EffectProcessor effectProcessor) override

Set the effect processor to be applied to the sound.

void stop() override

Stop playing the audio stream.

unsigned int getSampleRate() const

Get the stream sample rate of the stream.

virtual void onSeek(Time timeOffset)=0

Change the current playing position in the stream source.

virtual bool onGetData(Chunk &data)=0

Request a new chunk of audio samples from the stream source.

virtual std::optional< std::uint64_t > onLoop()

Change the current playing position in the stream source to the beginning of the loop.

~SoundStream() override

Destructor.

Time getPlayingOffset() const

Get the current playing position of the stream.

void play() override

Start or resume playing the audio stream.

void setPlayingOffset(Time timeOffset)

Change the current playing position of the stream.

Represents a time value.

SoundChannel

Types of sound channels that can be read/written from sound buffers/files.

Structure defining a chunk of audio data to stream.

const std::int16_t * samples

Pointer to the audio samples.

std::size_t sampleCount

Number of samples pointed by Samples.
