Constructor & Destructor Documentation

Dithering::Dithering

(

)

Member Function Documentation

virtual void Dithering::applyEffect ( Buffer *  b )

finaloverridevirtual

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

Implements Effect.

float Dithering::audioLinearDither ( float  sample, AudioDither *  dither  )

private

void Dithering::clearHistory ( )

private

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

finaloverridevirtual

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

Parameters

srate	Sample rate.
map	Map of channels.

Reimplemented from Effect.
