Review of EQuivocate auditory graphic EQ by Newfangled Audio / Eventide


Newfangled Audio have partnered with Eventide to produce an EQ based on the critical bands of the human ear. EQuivocate is exclusively available through Eventide (as an AAX/AU/VST plug-in for Mac OS X 10.7+ and Windows 7+) for an MSRP of $99.00 USD. It is also available as part of the Elevate mastering bundle (it is integrated into the Elevate mastering limiter and maximiser plugin) for $199 USD.

EQuivocate is the ideal EQ for naturally changing the tone of any sound, so it is perfect for mixing and mastering applications. As EQuivocate uses filters that are modelled on the human ear, each of its 26 bands tickles a different part of the inner ear, making any combination of settings sound as natural as ‘humanly’ possible. Combining this with a linear-phase filter shape that reduces pre-echo makes EQuivocate an EQ with a difference that can clearly be heard.

Use EQuivocate’s Match EQ feature to make the sound of your track match or complement the audio signal streamed to its sidechain. You can also use it to make a final master match the tone of a reference track, or help fit a sound into a dense mix. Unlike other match EQ plug-ins, EQuivocate provides a transparent match without trying to model imperceptible differences which can cause a match EQ to sound unnatural. Feed your favorite song or individual track into it and instantly morph your tone to match.

EQuivocate in use

The GUI has a clean modern look and is easy to use and navigate.

The top section has presets, load/save options and a drop down offering 3 different colour schemes. Underneath is an ‘active’ button which switches the effect on and off.

The input vu meter is on the left and output vu meter on the right of the display, both showing peak and rms levels. On the output is an ‘auto’ button. This option automatically compensates for any volume changes caused by any boosts or cuts to eq meaning no changes to volume level.

The main part of the display highlights how this plugin works differently to many other EQs because it is based on the ‘Mel’ scale which are preset values based on the critical bands of human hearing. Although they are fixed in terms of frequency, you have a lot of flexibility because you can skew the weighting of the centre frequency, use any number from 1 up to 26 bands and solo individual bands. Any changes you make triggers the custom mode which enables you to add and remove bands and draw EQ curves. The display shows the chosen number of bands at the bottom with EQ cuts and boosts above. You can select to show input and/or output monitoring for a visual representation of the changes you have made.

The match EQ is a cool feature, you load an audio file into the side chain and EQuivocate listens to the source and matches levels. There’s a scaling option which also features negative values that allow you to invert an EQ profile.

EQuivocate comes with 69 presets to get you started. These are excellent in their own right and can of course be tweaked to meet your requirements or you can start from scratch. I’m really impressed by how easy and flexible EQuivocate is to use. It handles mixing tasks such as taming low end, adding guitar presence, adding a bass presence or more extreme filtering; equally it can handle mastering tasks such as tightening and brightening. I really like how you can use EQuivocate quite subtly on individual tracks which adds up to a big change to the overall sound or use it for specific filtering effects such as producing a lo-fi sound.

EQuivocate compliments Elevate really well. Both plugins have been developed with the same principles of operation. EQuivocate can easily handle your EQ tasks and Elevate will definitely improve the quality of you finished song / mix. If you want to learn more about Elevate you can read my review.
