SplitEQ - Eventide Audio

More than a Great-Sounding EQ

SplitEQ™ is a groundbreaking EQ that offers a fundamentally new approach to corrective and creative audio equalization. It excels at Repairing, Rebalancing, Enhancing, and Widening any musical source or audio signal. SplitEQ is both a surgical tool for fixing particularly nasty problems and a creative tool as it opens up exciting new musical possibilities. More than just an EQ — It’s a new and better tool.

We all can hear the tonal and transient parts of sound; shouldn’t our EQs?

By Musicians For Musicians

SplitEQ reduces the distance between what you want to do and how you actually do it, and with fewer tradeoffs than other EQs. On a normal EQ, a low-shelf boost on a kick drum will yield muddiness rather than delicious oomph. A low cut on a low male vocal removes plosives but at the expense of low-end richness. SplitEQ gives you the surgical control to address the problematic part of a sound without losing the magic and without the need for additional tools.

SplitEQ is not just a corrective tool, it is also a new type of creative tool for taking your mixes to new heights through its independent L/R and Mid/Side panning. With SplitEQ every source is split into a pair of sonically distinct elements offering your music, mixes, and audio signals an extraordinary new level of musicality. 

Structural Split

The beating heart of SplitEQ analyzes the incoming audio and separates it into two separate streams:

  • Transient (noise, pops, mic plosives, vocal sibilance, attacks)
  • Tonal (sustained notes, harmonics, tone, ambiance)

8-Band Parametric EQ

SplitEQ’s filters are state-of-the-art, precise, and musical. The User Interface has been designed to streamline workflow. Add sheen to vocals without boosting sibilance or harshness. Enhance acoustic guitar harmonics while reducing string buzz. 

Stereo Imaging

Continuous L/R or Mid/Side panning of the Transient and Tonal components for each of the eight bands. The plug-in can be used to spatialize mono sources.

Graphical Display

High-res, real-time, spectrum analysis of audio components with multiple options for monitoring or comparison. SplitEQ also features Peak and RMS metering. 

SplitEQ Applications

Enhance

With independent control of the Tonal and Transient elements of an instrument, SplitEQ can be used to deliver punch, detail, sheen, breathiness, diction, tightness, thump, and pluck.

Repair

A unique audio repair and restoration tool, SplitEQ allows you to surgically tune the Transient and Tonal response independently. Remove a kick drum’s boom without losing its thump. 

Rebalance

SplitEQ allows versatile track placement in a mix. Easily perform multiple tasks not possible with any other EQ, like softening electric guitar strums while boosting cab reverb. 

Widen

SplitEQ allows for precise multi-band stereo image manipulation of the Tonal and Transient elements of each frequency band. L/R and Mid/Side panning are supported. Spatialize a beat like never before. 

X-Ray Vision

With SplitEQ you can hear and even see your sound in new ways. Our Structural approach mimics the way in which we interpret sound and our spectrum display offers an inside look into what you’re hearing. Solo only the transients, or a single band, or only the transients on a single band. Use the real-time spectrum analyzer to track down problematic resonances or transients by displaying the tonal and transient streams separately. SplitEQ adds a new dimension to your trouble-shooting toolkit.

Prepared for Repair

Our team took all the knowledge they had about recording, threw it out the window, then headed down to the studio to lay down some badly recorded tracks. Double-headed kick drum with no port? Check. Ill-advised mic placement on snare? Check. Why? To prove that SplitEQ works well on a wide range of sonically challenged material. We’ve created an entire folder of presets for those less-than-perfect recordings.

Batteries Included

SplitEQ comes with a Factory Library of over 150 presets to solve many of today’s standard corrective and complex mixing problems in a cleaner and faster way. The presets are designed to Enhance, Repair, Rebalance, and Widen various instruments including drums, vocals, guitar, and more. A/B comparison and Undo/Redo make it easy to explore ideas without losing where you started. 

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

Reviews

A groundbreaking solution.

SplitEQ introduces a revolutionary transient-based approach to EQ’ing. It’s going to fast become a staple tool in a mastering engineer’s toolbox. It’s a groundbreaking solution for adding punch, weight, and width to a mix.

SplitEQ is immensely versatile.

SplitEQ is immensely versatile, with a range of application as wide as any full-fledged modern parametric equalizer (as it can be used as such) but it reaches out much further with Structural Effects to deliver unprecedented results. Individual instruments, groups or busses can all benefit when mixing, and it’s an excellent option for designing unique sounds with samples or synthesizers.

An excellent high-end mastering tool.

To try to emulate what this plugin does in one instance you might need to employ a pretty high quality EQ and possibly a number of instances of a good transient designer. While it’s clearly an excellent high-end mastering tool, its range of presets and the inclusion of selectable algorithms for transient detection would suggest this is far from being a one trick pony.

Truly a step forward.

This Plugin is as powerful as it is revolutionary, and simple at the same time. Signal management at this level, with this interface, this ease, this constant management of all the work is truly a step forward.

An exciting progression.

All in all, SplitEQ is an exciting progression of Eventide’s Structural Split technology. It may not be as creative as Physion, but it’s arguably a lot more useful, and the preset folders called Enhance, Repair, Rebalance and Widen hint at its versatility. We can see this becoming an important utility for general mixing of individual tracks and fixing difficult problems, even at the mastering stage.

Beyond simple tonal sculpting.

SplitEQ undoubtedly gives you the ability to radically change the tonal character of sounds beyond simple tonal sculpting, and lets you sit sounds in a mix in a new, useful way.

…nothing could have prepared me for the SplitEQ.

This is truly a remarkable achievement in modern audio and I don’t care how they pulled it off, but I’m sure glad they did.

SplitEQ is a revelation, worth every penny.

SplitEQ is a revelation – easily amongst the most versatile and capable EQs out there, and worth every penny of its very reasonable asking price.

Effective and elegant.

SplitEQ has no real equivalent on the market and offers many ways to look at mixing problems in a new light…It’s truly a new tool that can provide effective and elegant answers to classic mixing problems.

You’ll wonder how you lived without it.

With its wide range of filter types and surgical capabilities, SplitEQ would be a desirable plugin even without the Spectral Split technology. When you factor in its ability to separate the transient from the tonal, you realize just how powerful and unique a plug-in it is. You’ll wonder how you lived without it.
