Jürgen Hock stftPitchShiftPlugin v1.1.5 Win Mac Linux [FREE]

Jürgen Hock stftPitchShiftPlugin is a free pitch-shifting effect for producers who want to change pitch and tonal character in real time. It supports polyphonic pitch processing, with optional formant preservation, and lets you adjust timbre independently of pitch. That makes it useful for hobby musicians and sound designers exploring alternate tunings, shifted harmonies, or different tonal textures in their audio.

Pitch and timbre changes can run together, so you can reshape both aspects within one effect. Enable formant preservation when you want to retain more of the sound’s original character while moving its pitch, or change timbre separately without altering the notes. Optional output normalization helps match the processed signal’s loudness to the input for easier level comparisons.

A basic interface gives you access to effect parameters while audio is running. Latency depends on the selected block size, with lower-latency operation possible at suitable settings. For Windows users, the VST3 format suits compatible hosts such as FL Studio and Ableton Live. The project also offers AU and LV2 formats, plus a standalone application.
