What is linear phase EQ?

A linear-phase equalizer uses linear-phase filters. This means that when a signal goes through the filter, all frequencies should experience the same time delay (known as “pure time delay”), which preserves the wave shape as much as possible. All filters have phase shift. ... The phase shift doesn't “color” the sound.

When should you use linear phase EQ?

The main reason to consider using a Linear Phase EQ is that when using minimal phase EQ, the combined signals will have a non-linear phase relationship that will vary both with Q and with degree of boost/attenuation. This isn't always a problem, and in fact can be a good thing.

Are analog EQ linear phase?

Typical equalizers (and all analog EQs) are referred to as minimum phase equalizers since one of the design goals for equalizers is to minimize phase shift artifacts. ... Thanks to digital signal processing, we can have equalizers that do not produce any phase shift artifacts. These EQs are called Linear Phase Equalizers.

Is Fabfilter linear phase EQ?

It is linear phase type filter. You change the frequency, but phase stays the same. But the filter rings before the transient as well as after.
