StkFloat tick (StkFloat input)
 Input one sample to the effect and return one output.
StkFramestick (StkFrames &frames, unsigned int channel=0)

Detailed Description

STK echo effect class.

This class implements an echo effect.

by Perry R. Cook and Gary P. Scavone, 1995 - 2010.


Constructor & Destructor Documentation

stk::Echo::Echo ( unsigned long  maximumDelay = (unsigned long) Stk::sampleRate()  ) 

Class constructor, taking the longest desired delay length (one second default value).

The default delay value is set to 1/2 the maximum delay length.


Member Function Documentation

StkFrames & stk::Echo::tick ( StkFrames frames,
unsigned int  channel = 0 
) [inline]

Take a channel of the StkFrames object as inputs to the effect and replace with corresponding outputs.

The StkFrames argument reference is returned. The channel argument must be less than the number of channels in the StkFrames argument (the first channel is specified by 0). However, range checking is only performed if _STK_DEBUG_ is defined during compilation, in which case an out-of-range value will trigger an StkError exception.

StkFrames & stk::Echo::tick ( StkFrames iFrames,
StkFrames oFrames,
unsigned int  iChannel = 0,
unsigned int  oChannel = 0 
) [inline]

Take a channel of the iFrames object as inputs to the effect and write outputs to the oFrames object.

The iFrames object reference is returned. Each channel argument must be less than the number of channels in the corresponding StkFrames argument (the first channel is specified by 0). However, range checking is only performed if _STK_DEBUG_ is defined during compilation, in which case an out-of-range value will trigger an StkError exception.
