DESCRIPTION::
|
|
This class implements a sanity test for the FluCoMa Real-Time Client FFT/IFFT Wrapper. It is part of the LINK:: Guides/FluidCorpusManipulation##Fluid Corpus Manipulation Toolkit::. For more explanations, learning material, and discussions on its musicianly uses, visit http://www.flucoma.org/

CLASSMETHODS::
|
|
|
|
METHOD:: ar
|
|
The audio rate version of the object.
|
|
|
|
ARGUMENT:: in
|
|
The input to be passed-through
|
|
|
|
ARGUMENT:: windowSize
|
|
The size of the buffered window to be analysed, in samples. It will add that much latency to the signal.
|
|
|
|
ARGUMENT:: hopSize
|
|
How much the buffered window moves forward, in samples. The -1 default value will default to half of windowSize (overlap of 2).
|
|
|
|
ARGUMENT:: fftSize
|
|
How large will the FFT be, zero-padding the buffer to the right size, which should be bigger than the windowSize argument, bigger than 4 samples, and should be a power of 2. This is a way to oversample the FFT for extra precision. The -1 default value will use the next power of 2 equal or above the windowSize.
|
|
|
|
ARGUMENT:: maxFFTSize
|
|
How large can the FFT be, by allocating memory at instantiation time. This cannot be modulated.
|
|
|
|
|
|
RETURNS::
|
|
Same as input, delayed by the windowSize.
|
|
|
|
|
|
EXAMPLES::
|
|
|
|
Summing with the inverse (gain of -1) with a delay of the latency gives us CPU-expensive silence.
|
|
CODE::
|
|
{ var source = PinkNoise.ar(0.1); DelayN.ar(source, delaytime:1024/s.sampleRate, mul: -1) + FluidSTFTPass.ar(source, 1024); }.play
