the input signal which has already been windowed and FFT'ed using Real1FFT
in mode 0 or 2.
The windows should have been rotated prior to the FFT so that the time
signal starts in the middle of the window and then wraps around.
the fft size which corresponds with the window size of the input
the normalized minimum frequency (frequency in Hz, divided by the sampling rate). should be greater than zero and less than or equal to 0.5.
the normalized maximum frequency (frequency in Hz, divided by the sampling rate). should be greater than zero and less than or equal to 0.5.
the number of bands or kernels to apply, spreading them evenly (logarithmically) across the range from minimum to maximum frequency.

A UGen that performs a constant Q spectral analysis, using an already FFT'ed input signal. For each input window, the output signal consists of
numBands
filter output values. These values are squared, since further processing might need to decimate them again or take the logarithm. Otherwise the caller needs to add.sqrt
to get the actual filter outputs.The default settings specify a range of nine octaves and
numBands = 432
thus being 48 bands per octave. At 44.1 kHz, the default minimum frequency would be 35.28 Hz, the maximum would be 18063.36 Hz.the input signal which has already been windowed and FFT'ed using
