FLAGSHIPA new kind of filter — The Golden-Ratio Series

PhiFilter

PhiFilter starts as a complete filter - nine types (low-pass, high-pass, band-pass, notch, comb, vowel, phaser, formant and a resonant ladder), drive, a selectable 12 or 24 dB slope and up to twelve phaser stages - driven by two modulators at once: a tempo-syncable LFO with four shapes and stereo phase offset, and an envelope follower whose attack and release let the input's own dynamics play the cutoff. On its own that is auto-wah, synced sweeps, vowel talk and slow phaser drift.

Then it opens a second dimension. Raise Phi Amount and the single filter blooms into a lattice of up to eight voices whose cutoffs are seeded from the golden ratio - the one spacing that keeps peaks from ever stacking on a shared resonance. Phi Spread fans the voices across the spectrum on the golden angle, Lattice Nodes steps through Fibonacci counts (1, 3, 5, 8), topologies from Golden Aperture to Mid/Side and geometries from Golden Spiral to Quasicrystal re-voice how the constellation sits, and a Phi Lattice motion source sweeps the whole field as one. At Phi Amount 0 the lattice is bypassed and the module is bit-exact identical to a conventional moving filter.
