Detailed Description

Audio Output Device, supporting 16 and 24 bit signed integer PCM.

This is the link between the audio classes of the module and the Qt audio system, inheriting QIODevice.

Definition at line 38 of file audioaoutputdevice.h.

Constructor & Destructor Documentation

AudioOutputDevice::AudioOutputDevice ( AudioOutput * audiooutput )

Constructor, resetting the member variables.

Parameters

audiooutput : Pointer back to the AudioOutput

Definition at line 39 of file audiooutputdevice.cpp.

Here is the call graph for this function:

AudioOutputDevice::AudioOutputDevice ( AudioOutput * audiooutput )

Member Function Documentation

bool AudioOutputDevice::connect ( const AudioDeviceParameters & parameters )

bool AudioOutputDevice::connect ( const AudioParameters & parameters )

Connect and start the audio output device.

Parameters

parameters : AudioDeviceParameters used for the connection. If the device name is empty the function attempts to connect the system's default audio output device.

Returns: True if device could be opened successfully.

Definition at line 58 of file audiooutputdevice.cpp.

Here is the call graph for this function:

void AudioOutputDevice::disconnect ( )

Stop the audio output device.

Definition at line 235 of file audiooutputdevice.cpp.

void AudioOutputDevice::disconnect ( )

int Log::getVerbosity ( )

inherited

Get the actual verbosity level.

Returns: : Verbosity level (1...4)

Definition at line 118 of file log.cpp.

qint64 AudioOutputDevice::readData	(	char *	data,
		qint64	maxSize
	)

finaloverrideprivate

Read PCM data.

This is a virtual function defined in QIODevice which is now implemented here. The call is redirected to the SoundGenerator.

Parameters

data	: Pointer to the PCM data
maxSize	: Maximal size to be generated in bytes

Returns: : Actual number of bytes that have been generated

Definition at line 272 of file audiooutputdevice.cpp.

Here is the call graph for this function:

qint64 AudioOutputDevice::readData	(	char *	data,
		qint64	maxSize

void Log::setVerbosity ( int verbosity )

inherited

Set the verbosity level of the class-specific messages.

Parameters

verbosity : Verbosity level (1...4)

Definition at line 107 of file log.cpp.

void AudioOutputDevice::setVolume ( double volume )

Set the global volume.

Parameters

volume : Volume level between 0 and 1

Definition at line 254 of file audiooutputdevice.cpp.

void AudioOutputDevice::setVolume ( double volume )

qint64 AudioOutputDevice::writeData	(	const char *	data,
		qint64	maxSize
	)

finaloverrideprivate

Empty implementation for writing without functionality.

This function is virtual in QIODevice and has to be implemented, even if it does nothing.

Parameters

data
maxSize

Returns: : Zero
