Detailed Description

Class for audio output to the soundcard.

Use this class to define the audio output.

Property Documentation

muted

bool Phonon::AudioOutput::muted

readwrite

This property tells whether the output is muted.

Muting the output has the same effect as calling setVolume(0.0).

Definition at line 96 of file audiooutput.h.

name

QString Phonon::AudioOutput::name

readwrite

This is the name that appears in Mixer applications that control the volume of this output.

See also

category

Definition at line 60 of file audiooutput.h.

outputDevice

AudioOutputDevice Phonon::AudioOutput::outputDevice

readwrite

This property holds the (hardware) destination for the output.

The default device is determined by the category and the global configuration for that category of outputs. Normally you don't need to override this setting - letting the user change the global configuration is the right choice. You can still override the device though, if you have good reasons to do so.

outputDeviceChanged

Definition at line 89 of file audiooutput.h.

volume

qreal Phonon::AudioOutput::volume

readwrite

This is the current loudness of the output (it is using Stevens' law to calculate the change in voltage internally).

See also

volumeDecibel

Definition at line 67 of file audiooutput.h.

volumeDecibel

qreal Phonon::AudioOutput::volumeDecibel

readwrite

This is the current volume of the output in decibel.

0 dB means no change in volume, -6dB means an attenuation of the voltage to 50% and an attenuation of the power to 25%, -inf dB means silence.

Constructor & Destructor Documentation

AudioOutput() [1/2]

Phonon::AudioOutput::AudioOutput ( Phonon::Category category, QObject * parent = nullptr )

explicit

Creates a new AudioOutput that defines output to a physical device.

Parameters

category

The category can be used by mixer applications to group volume controls of applications into categories. That makes it easier for the user to identify the programs. The category is also used for the default output device that is configured centrally. As an example: often users want to have the audio signal of a VoIP application go to their USB headset while all other sounds should go to the internal soundcard.

parent

QObject parent

outputDevice

AudioOutput() [2/2]

Phonon::AudioOutput::AudioOutput ( QObject * parent = nullptr )

explicit

Definition at line 75 of file audiooutput.cpp.

Member Function Documentation

category()

Category Phonon::AudioOutput::category

(

)

const

Returns the category of this output.

See also

AudioOutput(Phonon::Category, QObject *)

Definition at line 247 of file audiooutput.cpp.

isMuted()

bool Phonon::AudioOutput::isMuted

(

)

const

Definition at line 207 of file audiooutput.cpp.

mutedChanged

void Phonon::AudioOutput::mutedChanged ( bool )

signal

This signal is emitted when the muted property has changed.

As this property can change by outside sources, a UI element showing the muted property should listen to this signal.

name()

QString Phonon::AudioOutput::name

(

)

const

Definition at line 134 of file audiooutput.cpp.

outputDevice()

AudioOutputDevice Phonon::AudioOutput::outputDevice

(

)

const

Definition at line 253 of file audiooutput.cpp.

outputDeviceChanged

void Phonon::AudioOutput::outputDeviceChanged ( const Phonon::AudioOutputDevice & newAudioOutputDevice )

signal

This signal is emitted when the (hardware) device for the output has changed.

The change can happen either through setOutputDevice or if the global configuration for the used category has changed.

See also

outputDevice

setMuted

void Phonon::AudioOutput::setMuted ( bool mute )

slot

Definition at line 213 of file audiooutput.cpp.

setName

void Phonon::AudioOutput::setName ( const QString & newName )

slot

Definition at line 140 of file audiooutput.cpp.

setOutputDevice

bool Phonon::AudioOutput::setOutputDevice ( const Phonon::AudioOutputDevice & newAudioOutputDevice )

slot

Definition at line 259 of file audiooutput.cpp.

setVolume

void Phonon::AudioOutput::setVolume ( qreal newVolume )

slot

Definition at line 157 of file audiooutput.cpp.

setVolumeDecibel

void Phonon::AudioOutput::setVolumeDecibel ( qreal newVolumeDecibel )

slot

Definition at line 202 of file audiooutput.cpp.

volume()

qreal Phonon::AudioOutput::volume

(

)

const

Definition at line 181 of file audiooutput.cpp.

volumeChanged

void Phonon::AudioOutput::volumeChanged ( qreal newVolume )

signal

This signal is emitted whenever the volume has changed.

As the volume can change without a call to setVolume this is important to keep a widget showing the current volume up to date.

volumeDecibel()

qreal Phonon::AudioOutput::volumeDecibel

(

)

const
