Formant 0.3.0 is about pitch. Existing presets, sessions, and config keep working: new fields default cleanly when an older file loads.

New: Autotune

A real-time pitch-correction node. It detects the note you are singing and snaps it to the nearest note in a key and scale, with full control:

  • Key and Scale (chromatic, major, minor, major and minor pentatonic)
  • Strength: 0 leaves you alone, 1 is a full snap (the hard robotic sound)
  • Speed: a few milliseconds for the classic autotune warble, 100+ ms for natural correction
  • Preserve formants to keep your natural vocal character, and a tuning reference

It uses a YIN pitch detector feeding the phase vocoder.

Better Pitch node

  • Preserve formants toggle: shift pitch up or down while keeping your natural voice (no chipmunk). On by default for new Pitch nodes.
  • Dry/wet mix: blend a shifted harmony under your dry voice.

Fixes

  • The noise gate no longer swallows the start of sentences in voice-activity mode. A short lookahead opens the gate just before a word's onset, and the VAD decision now runs through the same hold and hysteresis as the level gate. The lookahead is adjustable (0 to 40 ms, default 12).
  • Some UI symbols showed as empty boxes on systems whose default font lacked those glyphs; Formant now falls back to a Windows symbol font.

Install

  • Run Formant-0.3.0-x64.msi (it upgrades an older install in place), or unzip Formant-0.3.0-portable.zip and run formant.exe.
  • To route into other apps you still need a virtual audio device such as VB-CABLE (free); Formant prompts you if one is missing.

Requires Windows 10 or 11. Free software under the GNU GPL v3 or later. Full CHANGELOG.
