IFFT Inverse Fast Fourier Transform

The inverse fast fourier transform converts from frequency content to a signal.  See also [FFT Overview].

IFFT(buffer)

s = Server.local; 

b = Buffer.alloc(s,2048,1);

SynthDef("help-noopFFT", { arg out=0,bufnum=0;

var in, chain;

in = WhiteNoise.ar(0.01);

chain = FFT(bufnum, in);

chain.inspect; // its an FFT

Out.ar(out, 

IFFT(chain) // inverse FFT

);

}).play(s,[\out,0,\bufnum,b.bufnum]);

See FFT for more examples.
