Max for Live *speq — Spectral Equalizer

*speq is a spectral processing audio effect, inspired by a Cycling ́74- tutorial-patch entitled "Forbidden Planet" by Gregory Taylor. It is based on a frequency-domain signal processing technique.

The input signal is converted to a frequency-domain signal using the Fast Fourier Transform (FFT) to be processed. The resulting signal is then converted back to a time-domain signal using the inverse FFT (IFFT).

The spectrum to be processed is divided into four sections which can be individually controlled like operating a graphical EQ which also can be randomly modulated by automation.

Further documentation can be found in the Max for Live device if Ableton Live ́s Help View is turned on.
