SplineEQ

SplineEQ is a unique linear phase equalizer I’ve enjoyed using in my mastering and sound design projects. Unlike minimum phase EQs, SplineEQ preserves the phase of your sound, which makes your mix sound cleaner and more natural. One of SplineEQ’s standout features is the spline-based filter design, where you can simply shape the EQ curve by placing points. This gives you a ton of flexibility without choosing from predefined filter types.

Even though the free version limits you to four bands per plugin instance, you can load multiple instances if needed. The full version offers up to 60 bands for detailed frequency adjustments. I also love the visual feedback it provides, with a responsive frequency analyzer that shows before-and-after results, helping me make precise changes. The truth is, you don’t need more than one equalizer to mix a song. All equalizers offer similar functionality with some notable, but not essential, differences.

You could pick one free EQ plugin and use it in all your projects. No one would notice, except for you, because the quality of your mix depends on your mixing skills, not the features of your equalization plugin. However, having multiple EQ VST plugins available in our DAW is beneficial for some. But why? Having the option to switch things up during a tedious project keeps things fresh and might help you finish the job faster.

Just like switching to a different keyboard helps me continue typing, using different equalizers during a long mixing session helps me focus and continue working even after I get tired.
