01Overview

Linear Phase Equalizer is built for tonal changes that should not sound like EQ. Linear phase processing leaves the phase response of the boosted or cut band untouched, which avoids the smearing that minimum-phase filters can add. Each of its six bands is fully parametric and can be set to high pass, low shelf, peaking, high shelf or low pass. The developer positions it as a precision tool for both single-track problem solving and full-mix equalization, and as a complement to a traditional EQ for adding color.

03In depth

Transparent Sound for Surgical and Broad EQ Moves

The plugin's main appeal is its linear phase behavior. IK Multimedia says this keeps boosts and cuts clean rather than colored, so the result feels natural.

In peaking mode, the bands can be set to a wide Q for broad tonal shaping or a very sharp Q for narrow, surgical cuts. Narrow cuts are useful for taming resonances or notching out unwanted noise without disturbing the fundamental tone of an instrument.

The same precision works on a single track or a full mix. On a mix bus, a wide Q keeps the change subtle enough to stay largely unnoticed.

Using It Alongside a Non-Linear-Phase EQ

The developer recommends pairing this EQ with a traditional, non-linear-phase EQ. The linear phase module handles corrective work in a transparent way, while the other EQ adds character.

IK Multimedia suggests Vintage Program EQ-1A as a color-focused companion in its own lineup.
