throatmorph · continuous cepstral spectral-envelope morph

Reshape the resonant body of your own recording — glassy to woody to vowel-like, continuously — while pitch and melody stay exactly the same.

The recording's own spectral envelope is lifted with the real cepstrum and morphed toward glassy, woody and vocal targets, then applied as a per-bin gain. Only the envelope moves — the harmonic fine structure that carries the notes is left untouched. Slide both hands left↔right to sweep the whole continuum, raise them to morph deeper, spread them to slide the vowel.
