Detailed Description

Base class for all Processors that applies a audio effect on the audio data.

Member Function Documentation

int calculateStepSize ( int  ,
int  numSamples 

Searches the modulation buffer for the minima and maxima and returns a power of two number according to the dynamic.

This can be used to check if there is some action in the modulation that needs splitting of processing to avoid parameter jumps without having to calculate each sample.

void checkTailing ( AudioSampleBuffer &  b,
int  startSample,
int  numSamples 

If your effect produces a tail, you have to call this method after your processing.

virtual AudioSampleBuffer& getBufferForChain ( int  )

Overwrite this method and return a reference to an internal buffer.

This is used to store the precalculated modulation values from preRenderCallback()

virtual bool hasTail ( ) const
pure virtual

Overwrite this method if the effect has a tail (produces sound if no input is active

virtual bool isTailingOff ( ) const

Checks if the effect is tailing off. This simply returns the calculated value, but the EffectChain overwrites this.

virtual void prepareToPlay ( double  sampleRate,
int  samplesPerBlock 

You have to override this method, since almost every effect needs the samplerate anyway.

Reimplemented from Processor.

virtual void renderNextBlock ( AudioSampleBuffer &  buffer,
int  startSample,
int  numSamples 
pure virtual

Renders the next block and applies the effect to the buffer.

Implemented in MonophonicEffectProcessor, and MasterEffectProcessor.

void saveBufferForTailCheck ( AudioSampleBuffer &  b,
int  startSample,
int  numSamples 

Takes a copy of the buffer before it is processed to check if a tail was added after processing.
