Eventide SplitEQ

New plugin introduces Structural Split tech to EQ, dividing audio into transients and tone to solve EQ problems precisely and in new ways


16 November 2021

Eventide releases SplitEQ, an advanced equalisation plug-in featuring its patented Structural Split technology. The culmination of a multi-year effort, SplitEQ works in a fundamentally different way from traditional EQs. It’s a new approach for corrective and creative rebalancing, enhancing, repairing, and widening any musical signal or other audio source.

SplitEQ is a parametric EQ with eight bands of precise, musical filters. What’s new and different is Eventide’s powerful Structural Split engine which divides the incoming audio into separate Transient and Tonal streams that feed the eight bands, and lets engineers view the two streams independently. This approach makes common EQ problems easy to solve even in a complex mix and opens up new musical possibilities.   

“We’re proud of what our developers have accomplished here. They’ve built on the Structural Split technology at the heart of our earlier plug-in, Physion, to do something truly unique: SplitEQ is a fundamentally new type of musical tool.” said Eventide’s founder, Richard Factor.   

SplitEQ takes the structure of sound into account. It splits any sound into two streams, mimicking human perception of its tonal and transient elements. After that, users can cut or boost only that part of the sound on which they’re focused. SplitEQ is not just a corrective tool. It is also a new type of creative tool for adding dimension to mixes through its independent Left/Right and Mid/Side panning options. As one of SplitEQ’s developers, Peter McCulloch, put it: “We can all hear the transient and tonal parts of a sound, shouldn’t our EQs?”   

SplitEQ features a real-time spectrum analyser so one can see and hear the sound in new ways. Users can Solo only the transients, a single band, or only the transients on a single band. The analyzer lets engineers track down problematic resonances or transients by displaying the tonal and transient streams separately, adding a new dimension to their troubleshooting toolkit.

Controls for the underlying Split technology allow fine tuning and experimentation. EQ curves can be globally or independently scaled. Peak, Notch, Bandpass, High-Shelf, Low-Shelf, Tilt Shelf, High-Pass, and Low-Pass filter types are available with slopes from 6 to 96 dB/octave.   

The plug-in’s graphical user interface includes zoom options and can be re-sized. SplitEQ includes a comprehensive library with over 150 presets. A/B buttons allow quick auditioning of two presets or settings plus Undo/ Redo functionality.   

Whether working on individual tracks, a full mix, or cleaning up a two-track loop, users will find SplitEQ to be an inspiring and powerful tool that allows them to approach material in a new, musically and sonically meaningful way.   

SplitEQ is available for Mac and PC in VST, AAX and AU formats for an introductory price of US$99 (reg. US$179) from Eventide and authorised dealers.
