| buffer |
a buffer to condition for FFT use |
| hop |
the hop size for timing triggers (defaults to 0.5) |
| polar |
a flag. If 0.0, the buffer will be prepared for complex data, if > 0.0, polar data is set up. |
// Reminder: This isn't the intended typical usage! It's OK to do this though.(x = { var mags, phases, chain, sig; // Create simple undulating magnitudes mags = { FSinOsc.kr(ExpRand(0.1, 1)).range(0, 1) }.dup(100); // Then give them a "rolloff" to make the sound less unpleasant mags = mags * ((1, 0.99 .. 0.01).squared); // Let's turn the bins on and off at different rates, I'm *sure* that'll sound interesting mags = mags * { LFPulse.kr(2 ** IRand(-3, 5)).range(0, 1) }.dup(100); // Let's ignore phase for now phases = 0.dup(100); chain = FFTTrigger(LocalBuf(512), 0.5); // Now we can do the packing chain = PackFFT(chain, 512, [mags, phases].flop.flatten, 0, 99, 1); sig = IFFT(chain); sig.dup}.play)x.free;b.free;
