H949 Harmonizer
Eventide
Vintage Harmonizer with Modern Power
The Eventide H949 Harmonizer® is a legendary pitch-shifting plugin that brings vintage character and wild, creative effects to your tracks—featuring de-glitched pitch shifting, delay, reverse, flange, and more. Perfect for music producers and sound designers, it’s your go-to plugin for iconic vocal doubling, mind-bending modulation, and rich stereo depth.


The World’s First Time Machine
Building on the legacy of the H910 pitch shifter, the H949 Harmonizer® was Eventide’s first de-glitched pitch-shifter. Produced from 1979–1984, it introduced the MicroPitch effect, which used a proprietary single-sideband modulation technique for precise control of small pitch shifts. The H949 also offered unique flange, reverse, and randomized pitching effects.
The same legendary effects processor used by Jimmy Page and cherished by Suzanne Ciani has been faithfully recreated as a full-featured plug-in. Designed to inspire a new world of sound—from basic engineering and sound sculpting tasks to demonic space creations, robotic distortions, and more—the H949 is a comprehensive special effects tool.
Authentic De-Glitched Pitch Shifting
The H949 algorithm uses a proprietary auto-correlation algorithm to make intelligent splicing decisions. Users can choose a simple cross-fade algorithm, resulting in characteristic glitching, or opt for the de-glitched mode for smoother transitions. This flexibility allows for a wide range of creative possibilities, from subtle pitch adjustments to extreme effects.
Dual Harmonizer for Enhanced Creativity
This native plug-in version includes the H949 Dual, which recreates the popular technique of running two units in parallel. This setup is ideal for creating lush doubling, stereo widening, and simultaneous shifting of pitch up and down, offering a rich and expansive sound.
