Very Happy here i come again..
let's make some two-line chuck crazies with those new UAna capabilities.

I still can't produce any usable codes with UAna(s) in two lines..
I'm still lost in the documents hahaha...

this is a big challenge for me. Shocked

80 characters per line max, right?
Code:

IFFT i=>dac;complex c[512];int A;
while(1){#(++A%.33,A%1.65)=>c[A%512]; i.transform(c);1024::samp=>now;}


Note really Uana as no real analysis takes place so I'm not sure this is within the rules but I like it (warning, nasty!)

Code:
dac=>FFT f =^ IFFT i=>dac;Shakers s => dac;.98 => dac.gain;4=>s.preset;
while(i.size()::samp=>now){i.upchuck();(maybe*maybe*maybe)=>s.noteOn;}


A lot more friendly then my last one. Abusing the loop as a resonator.

Code:
// Economical Fried Egg
Noise a => FFT b =^ IFFT c => dac; 2 => b.size => c.size;
while(1) c.upchuck(), (1 + a.last())::ms * 40 => now;


added some modification for use with SinOsc:

Code:
// (another) Intergalactic Soundcheck
SinOsc a => FFT b =^ IFFT c => dac; b.size(c.size(5)); a.freq(.01);
while(1) c.upchuck(), (1.1 + a.last())::ms * .1 => now;

Cool! I like how it gets "almost stuck" then starts again.


documentation wrote:

//(note: do not use the returned array for anything
// other than reading/setting windows in FFT/IFFT).


Why not?

Code:
// Step s => PoleZero p => dac;.99 => p.blockZero; int A;
// while(4::samp => now) Windowing.hann(64)[++A%64] => s.next;


or, in one line if you don't care about the DC offset;
Code:

Step s => dac;int A;while(4::samp => now) Windowing.hann(64)[++A%64] => s.next;


Quite perverse and stupid but it works.

i've just had time to experiment more with fft, ifft
here's my latest attempts. thanks for playing with them ^_^

Code:
SqrOsc s => FFT a =^ IFFT b => dac => a; int i;
while(true) { b.upchuck(); a.size(b.size(i + 2))::samp => now; i++; }


Code:
Noise s => FFT a =^ IFFT b => dac => a; 1 => int i;
while(true) { b.upchuck(); a.size(b.size(i % 1000 + 100))::samp => now; 13 +=> i; }
