Detailed Description

A SamplerVoice that streams the data from a StreamingSamplerSound.

It uses a SampleLoader object to fetch the data and copies the values into an internal buffer, so you don't have to bother with the SampleLoader's internals.

Member Function Documentation

bool canPlaySound ( SynthesiserSound *  )

inline

Always returns true.

double getDiskUsage ( )

inline

Returns the disk usage of the voice.

To get the disk usage of all voices, simply iterate over the voice list and add all disk usages.

hlac::HiseSampleBuffer * getTemporaryVoiceBuffer

(

)

Returns the sampler's temp buffer.

void initTemporaryVoiceBuffer ( hlac::HiseSampleBuffer *  bufferToUse, int  samplesPerBlock  )

static

Call this once for every sampler.

void prepareToPlay	(	double	sampleRate,
		int	samplesPerBlock
	)

Initializes its sampleBuffer.

You have to call this manually, since there is no base class function.

void renderNextBlock ( AudioSampleBuffer &  outputBuffer, int  startSample, int  numSamples  )

override

Adds it's output to the outputBuffer.

void resetVoice

(

)

resets everything.

void setDynamicPitchFactor ( double  pitchMultiplier )

inline

Changes the pitch of the voice after the voice start with the given multiplier.

void setPitchFactor	(	int	midiNote,
		int	rootNote,
		StreamingSamplerSound *	sound,
		double	globalPitchFactor
	)

You have to call this before startNote() to calculate the pitch factor.

This is necessary because a StreamingSamplerSound can have multiple instances with different root notes.

void setPitchValues ( const float *  pitchDataForBlock )

inline

You can pass a pointer with float values containing pitch information for each sample and the delta pitch value for each sample.

The array size should be exactly the number of samples that are calculated in the current renderNextBlock method.

void setStreamingBufferDataType

(

bool

shouldBeFloat

)

Set this to false if you're using HLAC compressed monoliths.

void setTemporaryVoiceBuffer

(

hlac::HiseSampleBuffer *

buffer

)

Gives the voice a reference to the sampler temp buffer.

void startNote ( int  midiNoteNumber, float  velocity, SynthesiserSound *  s, int    )

override

starts the streaming of the sound.

void stopNote	(	float	,
		bool
	)

Clears the note data and resets the loader.
