Frap Tools FUMANA - Dual 16 Bands Spectral Editor
While the upper section provide access to each main filter’s direct output, the lower section has 4 voltage controllable parameters to manage two independent functions for further spectral editing: tilt and parametric scan.
The tilt, as the name suggest, tilts the spectrum, adding and subtracting amplitude to the 16 bands, emphasizing lower or high bands, and attenuating high or lower bands: this is managed only with the green potentiometer.
The parametric scan, instead, works with three parameters: peak/notch, band selector and width. Like in a parametric equalizer, where is possible to set peak/notch gain, frequency and slope, the FUMANA uses three parameters to set which is the center band to perform this manipulation, then if that band should be emphasized or attenuated, and how this action is extended to nearby bands.
In addition to the 16 bandpass outputs, there are other 4 outputs provided: the all bands output, the all envelope followers output, the odd bands and the even bands output. These two have the options to be inverted in phase with two switches, in order to obtain even more combination when summed together, maybe/also with the “all bands output”, using, for example the 333 module.
Since a spectral transfer tool may be used as a “vocoder-like-effect”, the FUMANA provides an input for an external noise which may be used for unvoiced (fricative/sibilants) sounds as words containing or starting with s, f, z, ch and other fricative sounds ([s] [z] [ʃ] [tʃ] [dʒ] [ts] [ʂ] [f] [v] [ɸ] [θ] [ʒ] etc etc).
The FUMANA is an all analog dual filter bank with various control to access dynamically these bands. Each filter bank is composed of an array of 16 independent 48dB/oct bandpass...
