<span class="sd"> FFT analyses an input signal and converts it into the spectral</span>
<span class="sd"> domain. Three audio signals are sent out of the object, the</span>
<span class="sd"> `real` part, from bin 0 (DC) to bin size/2 (Nyquist), the</span>
<span class="sd"> `imaginary` part, from bin 0 to bin size/2-1, and the bin</span>
<span class="sd"> number, an increasing count from 0 to size-1. `real` and</span>
<span class="sd"> `imaginary` buffer's left samples up to size-1 are filled</span>
<span class="sd"> with zeros. See notes below for an example of how to retrieve</span>
<span class="sd"> each signal component.</span>
<span class="sd"> :Parent: :py:class:`PyoObject`</span>
<span class="sd"> :Args:</span>

<span class="sd"> Input signal to process.</span>
<span class="sd"> size: int {pow-of-two > 4}, optional</span>
<span class="sd"> FFT size. Must be a power of two greater than 4.</span>
<span class="sd"> The FFT size is the number of samples used in each</span>
<span class="sd"> analysis frame. Defaults to 1024.</span>
<span class="sd"> overlaps: int, optional</span>
<span class="sd"> The number of overlaped analysis block. Must be a</span>
<span class="sd"> positive integer. More overlaps can greatly improved</span>
<span class="sd"> sound quality synthesis but it is also more CPU</span>
<span class="sd"> expensive. Defaults to 4.</span>
<span class="sd"> wintype: int, optional</span>
<span class="sd"> Shape of the envelope used to filter each input frame.</span>
<span class="sd"> Possible shapes are :</span>
<span class="sd"> 0. rectangular (no windowing)</span>
<span class="sd"> 1. Hamming</span>
<span class="sd"> 2. Hanning</span>
<span class="sd"> 3. Bartlett (triangular)</span>
<span class="sd"> 4. Blackman 3-term</span>
<span class="sd"> 5. Blackman-Harris 4-term</span>
<span class="sd"> 6. Blackman-Harris 7-term</span>
<span class="sd"> 7. Tuckey (alpha = 0.66)</span>
<span class="sd"> 8. Sine (half-sine window)</span>
<span class="sd"> .. note::</span>
<span class="sd"> FFT has no `out` method. Signal must be converted back to time domain,</span>
<span class="sd"> with IFFT, before being sent to output.</span>
<span class="sd"> FFT has no `mul` and `add` attributes.</span>
<span class="sd"> Real, imaginary and bin_number parts are three separated set</span>
<span class="sd"> of audio streams. The user should call :</span>
<span class="sd"> | FFT['real'] to retrieve the real part.</span>

<span class="sd"> Inverse Fast Fourier Transform.</span>
<span class="sd"> IFFT takes a signal in the spectral domain and converts it to a</span>
<span class="sd"> real audio signal using an inverse fast fourier transform.</span>
<span class="sd"> IFFT takes two signals in input, the `real` and `imaginary` parts</span>
