THROATGOAT

Beta

Reshape any voice. Keep the pitch.

THROAT GOAT reshapes the vocal tract, not the performance. Move the formants, the gender, the tilt and the resonance. At each extreme of SHIFT and GENDER on 1.1.6, the median pitch moved 1.4 cents or less.

The trial runs 14 days, even where the plug-in's own screen says 5.

Move the voice yourself.

A browser build of THROAT GOAT's engine, running on a real acapella. It is not yet proven identical to the plug-in you install, so the free 14-day trial runs the real one. Turn the knobs.

The idea

Change the voice. Not the take.

Every voice is a pitch and a tube. THROAT GOAT leaves the notes where they were sung and reshapes the tube, so a performance keeps its timing, its phrasing and its intonation while the character in front of it changes completely.

The tube

A vocal tract you can move

SHIFT lengthens or shortens the throat, GENDER scales the formants between male and female, FOCUS sharpens or softens the resonances, and TILT sets the brightness. Small moves flatter a take. Large ones make a different singer.

The pitch

The notes stay where they were sung.

The engine warps the spectral envelope on a fixed hop, with no pitch tracking and no grains. At each extreme of SHIFT and GENDER on 1.1.6, the median pitch moved 1.4 cents or less.

Inside THROAT GOAT

Four knobs make the voice.

A true spectral envelope, tracked independently of the singer's pitch, then warped exactly where you ask and nowhere else.

01
Shift±12 semitones
Formant shift. Down for a bigger, darker throat, up for a smaller, brighter one. The note stays where the singer left it.
02
Gender±100 %
Scales the formants across the male and female range. The fastest route from a voice to a different person.
03
Protectstarts at 75 %
Consonants and sibilants are guarded while the vowels move, so a big shift keeps its diction instead of lisping. You will want it there.
04
Focus & Tilt±6 dB / oct
FOCUS tightens or softens the resonances. TILT tips the whole spectrum for brightness that follows the voice rather than an EQ curve.
05
Motion0.05 to 12 Hz
Move the formants or the tilt on their own. Slow for a voice that breathes, fast for something that should not be human.
06
Drive & Mixlatency-matched
DRIVE saturates the effect, not the source. MIX blends to a latency-matched dry, so a partial setting never phases against the original.
Steal · timbre transfer

Take a voice. Wear it.

GRAB captures the vocal-tract signature of any voice you play it. STEAL moves your source toward it, MORPH travels between two of them.

01
Grab A, Grab Btwo capture slots
Play a voice and capture its envelope. Two slots, so you always have somewhere to travel from and somewhere to travel to.
02
Stealblend amount
Blend your singer toward the captured timbre. At low amounts it is a family resemblance. High up it is somebody else entirely.
03
MorphA to B
Ride between A and B. Automate it and the voice changes identity across a line, still on pitch, still in time.
The null

At SHIFT 0, GENDER 0 and no vowel colour, the warp gain is exactly 1 and the engine hands back what you fed it. Line the output up against the dry, at exactly the latency THROAT GOAT reports, and the residual sits more than 75 dB down: far below anything you will ever hear. THROAT GOAT sitting on a channel doing nothing does nothing, and that is measured, not promised. SOLO hands you the difference so you can hear precisely what it added.
