PhaseyQ

The wonkiest EQ in existence

Traditional EQs move phase as a side effect of moving gain, with no control over it. Linear-phase EQs go the other way and try to erase phase shift entirely. PhaseyQ locks the two together instead - phase and gain, manipulated as one, brothers in arms as it was always meant to be. Or something.

Five parametric peak bands operating unlike any other EQ, with Lo & Hi filters that can also be set to behave like nothing else. Directly compared to a standard EQ it's subtle on a single source, but comes alive on multi-mic instruments or parallel chains where that phase relationship makes all the difference.

Phase as a control, not a side effect

A conventional EQ is minimum-phase: its phase smear is small - maybe a few tens of degrees on its skirts and zeroed at its centre frequency.

PhaseyQ doesn't work on traditional filters. Instead, every tweak dynamically recalculates a single, custom impulse response. The same underlying mechanism as a linear-phase EQ, but applied in a radically different way.

On a single source the effect is subtle - a slight softening or tightening around the band. It comes alive on correlated pairs: mic pairs, parallel chains, doubled tracks. Two versions of the same signal comb-filter against each other, and where the notches fall is set entirely by their relative phase - PhaseyQ lets you steer that relationship much more tightly.

FAQ

Does PhaseyQ require an iLok or dongle?

No. Activation is handled online through a license key, with no dedicated hardware required.

The Invert button changes the sound but the EQ curve doesn't move. Is that right?

Yes, by design. Invert flips that band's phase contribution only - a +18 dB boost that was +180° becomes −180°, but the magnitude curve doesn't move at all. Use it to fix a specific phase cancellation without touching tone.

Does PhaseyQ add latency?

Yes, a significant amount - the whole plugin is a single FIR convolution, and the kernel needs lookahead to be linear-phase. Any host with delay compensation handles it automatically. Live tracking through PhaseyQ is not recommended; insert it afterwards instead.

What is pre-ring, and should I worry about it?

It's the sonic cost of not being minimum-phase. A filter that isn't minimum-phase spreads energy symmetrically around the impulse rather than trailing behind it, so steep cuts and slopes get a small smear ahead of the transient. Every linear-phase EQ has this - PhaseyQ is in the same family.

How many machines can I activate it on?

Up to 3 devices per license. Moving to a new machine is free: deactivate on the old one and activate on the new one, with a 14-day cooldown before that license can go back on the device you removed it from.

Is PhaseyQ really free?

Yes. Full functionality, no trial limits, the same lifetime license terms as every other NYX-DSP plugin - just no charge.
