DESCRIPTION::
A sanity test for the FluCoMa Real-Time Client FFT/IFFT Wrapper footnote::This  was made possible thanks to the FluCoMa project (http://www.flucoma.org/) funded by the European Research Council (https://erc.europa.eu/) under the European Union’s Horizon 2020 research and innovation programme (grant agreement No 725899).::


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. This is not modulatable.

ARGUMENT:: hopSize
	How much the buffered window moves forward, in samples. This is not modulatable.

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 default to windowSize. This is not modulatable.

returns::
	Same as input, delayed by the windowSize.


EXAMPLES::

code::
	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) + FDSTFTPass.ar(source, 1024, 256, 1024); }.play
	::
	Larger, oversampled, FFT
	code::
	{ FDSTFTPass.ar(PinkNoise.ar(0.1), 2048, 128, 8192) }.play
	::
	Stereo Input Tests.
	code::
	{ FDSTFTPass.ar([SinOsc.ar(222,mul: 0.1), PinkNoise.ar(Decay.ar(Impulse.ar(0.666,mul: 0.1), 0.5))], fftSize:1024)}.play
	::
	Stereo Parameter Tests.
	code::
	{ FDSTFTPass.ar(SinOsc.ar(222,mul: 0.1), [1024,8192],256,8192)}.play
