High pass filter (or low cut filter) should be one of the most basic and essential EQ tools in your mixing arsenal. It’s a way to clean up your mix and / or to make the most important elements (such as kick and bass in EDM) to really stand out from the rest of the material.
To get the idea what I’m talking about, watch these two video tutorials below. The first video is made by a Robert Anthony Perez from AudioTuts and the second video is from The Recording Revolution’s mixing video tips series.
In FL Studio, using high pass filter is simple: just load a Fruity Parametric EQ 2 to your Mixer track(s), load a preset ’40Hz cut’ and set the frequency to wherever you wan’t to start the cutting (usually around 150-300Hz, but of course, that depends on your audio material).
The end. Hopefully these tips came useful to you. 😎
