The H910 plug-in for AAX, VST, and AU is a powerful creative tool that faithfully recreates the original hardware frequency range. Nothing else comes close to it in terms of sound. The H910 may be heard on countless groundbreaking works by musicians ranging from AC/DC to David Bowie to Frank Zappa, thanks to its unique blend of pitch shifting, modulation, pitch tracking and delay.

The world’s first digital effects processor was the Eventide H910 Harmonizer.

Antares Harmony Engine is the best Harmonizer VST Plugin in 2023. Harmony Engine gives you the tools you need to create any vocal arrangement you can think, with four separate harmony voices, a number of customizable harmony generating modes, and humanization elements for more realistic sounding performances.
