More than a Great-Sounding EQ

Request Demo / Own Physion? Get a Crossgrade

SplitEQ is a groundbreaking EQ plugin 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 it opens up exciting new musical possibilities. More than just an EQ—It’s a new and better tool.

At first glance, it’s a parametric EQ plugin with 8-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 8 bands. This approach makes common EQ problems easy to solve—even in a complex mix—and it opens up new and exciting musical possibilities.

  • Want to soften the transients? Use the master Transient Gain slider.
  • Remove plosives or de-ess? EQ only the Transient.
  • Reduce snare ring? Put a filter on the Tonal mids.

By applying EQ and panning to Transient and Tonal separately, you can fix many of the problems normally attempted by complex combinations of EQ, compression, transient designers, de-essers, multi-band compression, spatial processors, or dynamic EQ. Simplify and declutter your workflow, get better results and create new sounds.

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. 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.

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.

Amazing results with piano samplers

I often find that the piano doesn't sound exactly how I want it, no matter what I try with velocity settings etc. Using SplitEQ was the first time that I could balance all parameters exactly how I wanted them to sound.

Mark B.
Very useful and easy to use

I really like this plugin. It allows me to quickly get results that would otherwise be very complicated and require several plugins.
