virtual

Destructor.

Member Function Documentation

applyEffect()

virtual void applyEffect ( Buffer * b )

pure virtual

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

audioParameters()

const AudioParameters audioParameters

(

)

const

Returns audio parameters for output data.

channelMap()

const ChannelMap & channelMap

(

)

const

Returns map of channels

channels()

int channels

(

)

const

Returns channels number.

configure()

virtual void 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.

create()

Effect * create ( EffectFactory * factory )

static

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

enabledFactories()

QList< EffectFactory * > enabledFactories ( )

static

Returns a list of enabled effect factories.

factories()

QList< EffectFactory * > factories ( )

static

Returns a list of effect factories.

factory()

EffectFactory * factory

(

)

const

Returns assigned factory object.

file()

QString file ( const EffectFactory * factory )

static

Returns plugin file path.

Parameters

factory

Effect plugin factory.

findFactory()

EffectFactory * 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.

isEnabled()

bool isEnabled ( const EffectFactory * factory )

static

Returns true if input plugin is enabled, otherwise returns false

Parameters

factory

Effect plugin factory.

sampleRate()

quint32 sampleRate

(

)

const

Returns samplerate.

setEnabled()

void 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)
