Voice Changer — Voice Box Violet · Q-Branch A3-4

The fences — read these first

Consent-only: this transforms your own voice, or a consenting adult's voice, and nothing else.
It never imitates another real person — no cloning a voice you don't have the rights and consent to use.
It never touches the child's surfaces or any child-facing surface — the house's no-synthetic-voice fence stands untouched.
Anything published that uses transformed voice carries a synthetic-voice disclosure.

Honesty law — what this page actually is

This page changes the pitch and character of your own voice, in your browser, and sends nothing anywhere. It is effects, not identity conversion — full neural voice conversion is the house-hardware lane; see the packet.

Every effect below is labeled as what it honestly is: a playback-rate pitch shift, an EQ chain, or ring modulation. None of it converts your voice into anyone else's voice, and none of it is a neural model.

1 · Record a short clip of your own voice

Press RECORD, speak for a few seconds, then press STOP. Your browser will ask for microphone permission — the recording stays in this page's memory until you download it or close the tab.

Status: ready. No clip recorded yet.

Original clip (unmodified, exactly as recorded)

2 · Apply transformations — locally

Pitch shift — honestly: resample / playback-rate pitch shift (raises or lowers pitch and changes speed together, like speeding up or slowing down a tape). Range −12 to +12 semitones. Current: 0 semitones Formant-flavored EQ — honestly: a peaking EQ filter that emphasises a chosen band, which hints at a larger or smaller vocal character without moving any real formants. Centre frequency: 1000 Hz

Character presets — each one is a named combination of the pitch shift and EQ above, plus (for Robot) ring modulation. Nothing more is hiding in them:

Radio: Band-limited EQ: a high-pass and low-pass pair keep only the telephone-like middle band, with a presence boost and mild saturation. Honestly: a band-pass style EQ chain.
Deep: Playback-rate pitch shift down, plus a low-shelf EQ boost and a high-shelf cut. Honestly: slower, lower, darker — pitch and EQ, not a different person.
Bright: Playback-rate pitch shift up (slight), plus a high-shelf EQ boost. Honestly: faster, higher, lighter — pitch and EQ.
Robot: Ring modulation: your voice multiplied by a steady oscillator tone (about 45 Hz), which adds metallic side-tones. Honestly: ring modulation, a classic electronic effect — not a robot voice model.

Rendering happens offline in this tab and produces a WAV file in memory.

Transformed clip

If you publish anything made with the transformed clip, fence 4 applies: Anything published that uses transformed voice carries a synthetic-voice disclosure.

What this page is not

This is an effects slice, not neural voice conversion. The 3080-class house-hardware lane — open-source, local, real-time voice-conversion tooling trained only on the owner's own voice (or a consenting adult's) — is described in PACKET-A3-4.md in this folder. That packet installs nothing; it is the honest plan, with its code-screening gate, for a separate sitting.
