Detailed Description

A voice renders audio samples for a given note / pitch.

Constructor & Destructor Documentation

Voice()

Voice::Voice	(	double	sampleRate,
		const MIDI::Channel &	channel,
		const Setup &	setup
	)

Construct a new voice renderer.

Parameters

sampleRate	the sample rate to use for generating audio
channel	the MIDI state associated with the renderer
setup	the zones to apply to build the generator state

canLoop()

bool SF2::Render::Voice::Voice::canLoop ( ) const

inline

Returns

true if the voice can enter a loop if it is available

isActive()

bool SF2::Render::Voice::Voice::isActive ( ) const

inline

Returns

true if this voice is still rendering interesting samples

keyReleased()

void SF2::Render::Voice::Voice::keyReleased ( )

inline

Signal the envelopes that the key is no longer pressed, transitioning to release phase.

render()

double SF2::Render::Voice::Voice::render ( )

Returns

renders a sample
