Constructor & Destructor Documentation

Effect::Effect ( )

default

Object contsructor.

virtual Effect::~Effect ( )

virtualdefault

Destructor.

Member Function Documentation

virtual void Effect::applyEffect ( Buffer *  b )

pure virtual

Adds audio effect to the buffer b. Subclass should implement this function.

Implemented in Dithering, ChannelConverter, and ReplayGain.

AudioParameters Effect::audioParameters

(

)

const

Returns audio parameters for output data.

const ChannelMap& Effect::channelMap

(

)

const

Returns map of channels

int Effect::channels

(

)

const

Returns channels number.

virtual void Effect::configure ( quint32  srate, ChannelMap  map  )

virtual

Prepares object for usage. Subclasses that reimplement this function must call the base implementation.

Parameters

srate	Sample rate.
map	Map of channels.

Reimplemented in Dithering, and ChannelConverter.

static Effect* Effect::create ( EffectFactory *  factory )

static

Creates effect object from factory. Returns effect objects if factory is enabled, otherwise returns 0.

static QList<EffectFactory*> Effect::enabledFactories ( )

static

Returns a list of enabled effect factories.

static QList<EffectFactory*> Effect::factories ( )

static

Returns a list of effect factories.

Referenced by TTK::TTKQmmp::effectPlugins(), TTK::TTKQmmp::enabledEffectPlugin(), MusicPluginWidget::loadPluginsInfo(), and TTK::TTKQmmp::showEffectSetting().

EffectFactory* Effect::factory

(

)

const

Returns assigned factory object.

static QString Effect::file ( const EffectFactory *  factory )

static

Returns plugin file path.

Parameters

factory

Effect plugin factory.

Referenced by MusicPluginWidget::loadPluginsInfo().

static EffectFactory* Effect::findFactory ( const QString &  shortName )

static

Finds effect factory object by short name shortName. Returns effect factory pointer. If no match is found, 0 is returned. The search is case sensitive.

static bool Effect::isEnabled ( const EffectFactory *  factory )

static

Returns true if input plugin is enabled, otherwise returns false

Parameters

factory

Effect plugin factory.

static void Effect::loadPlugins ( )

staticprivate

quint32 Effect::sampleRate

(

)

const

Returns samplerate.

static void Effect::setEnabled ( EffectFactory *  factory, bool  enable = true  )

static

Sets whether the effect plugin is enabled.

Parameters

factory	Effect plugin factory.
enable	Plugin enable state (true - enable, false - disable)
