Output for a patcher loaded by pfft~ The fftout~ object provides an signal output to a pfft~ object. Cycling '74 MSP MSP FFT Real Output 1 of Patcher TEXT_HERE Imaginary Output 1 of Patcher TEXT_HERE Outlet number Determines the outlet number in the pfft~ which will receive the output of the fftout~ object. Outlet assignments start at 1 for the leftmost outlet of pfft~. Multiple fftout~ objects will typically have different outlet numbers. Window envelope function Tells fftout~ which window envelope function to use when overlapping fft's on the input signal. The options are square (i.e. no window envelope), hanning (the default), and hamming. If the argument nofft is used, then the fftout~ will echo its input signal to its output without performing a Fast Fourier transform. This allows you to output raw control signals from the pfft~ to the parent patcher. Note that when the nofft option is used, overlap-adding is still being performed to create the output signal. Function depends on inlet In left inlet: The real part of a signal that will be inverse-transformed back into the time domain.

In right inlet: The imaginary part of a signal that will be inverse-transformed back into the time domain.
Note that the real and imaginary inlets of fftout~ expect only the first half of the spectrum, as output by fftin~. This half-spectrum is called a spectral frame in pfft~ terminology. The fftout~ object performs an inverse Fast Fourier Transform and applies a windowing function (an envelope), allowing the pfft~ object to manage the overlap-add of the output signal windows. The fftout~ object transforms frequency domain signals back into the time domain, at which point they are overlap-added and output by the corresponding outlet in the pfft~ object in which the subpatcher is loaded. The fftout~ object itself has no outlets.
