Description

Service that provides audio input and output processing directly for hardware audio devices. Provides static methods to poll the current system for available audio devices using portaudio.

Constructor & Destructor Documentation

◆ AudioService()

AudioService ( ServiceConfiguration * configuration )

◆ ~AudioService()

~AudioService ( )

default

Member Function Documentation

◆ enqueueTask()

void enqueueTask ( TaskQueue::Task task )

Enqueue a task to be executed within the process() method for thread safety

◆ getNodeManager()

NodeManager& getNodeManager ( )

Returns: the audio node manager owned by the audio service. The node manager contains a node system that performs all the DSP.

◆ init()

bool init ( nap::utility::ErrorState & errorState )

overridevirtual

Initializes portaudio.

Reimplemented from Service.

◆ onAudioCallback()

void onAudioCallback	(	float **	inputBuffer,
		float **	outputBuffer,
		unsigned long	framesPerBuffer
	)

This function is typically called by a hardware callback from the device to perform all the audio processing. It performs memory management and processes a lockfree event queue before it invokes the NodeManager::process() to process audio.

Parameters

inputBuffer	an array of float arrays, representing one sample buffer for every channel
outputBuffer	an array of float arrays, representing one sample buffer for every channel
framesPerBuffer	the number of samples that has to be processed per channel

◆ shutdown()

void shutdown ( )
