How to fix muddy mixes in FL Studio?

Dec 10, 2025

To fix muddy mixes in FL Studio, start by using high-pass filters (low-cuts) on individual tracks to remove unnecessary low frequencies that aren't essential to each sound's character. Target the 200-500 Hz range with parametric EQ to cut problematic low-mid frequencies that cause muddiness, and make sure your bass and kick drum stay in mono using a mid/side EQ to keep your low end tight and focused. Additionally, watch your volume levels and make sure you're not overloading the mix, as excessive volume can contribute to a cluttered, muddy sound. Finally, create separation by using surgical EQ cuts to carve out space for each element to breathe in the frequency spectrum.

Learning to identify and eliminate muddiness takes practice and trained ears, which is exactly what you develop through Futureproof Music School's Mixing Fundamentals courses and expert feedback from Futureproof Mentors.

Should I use high-pass filters on every track to prevent mud buildup?

Not every track needs a high-pass filter, but most do. Start by filtering out frequencies below 80-100 Hz on non-bass elements like synths, vocals, and pads, then use your ears to adjust from there.

What's the ideal frequency range to cut when removing mud from my mix?

Mud typically lives between 200-500 Hz, with the worst offenders usually sitting around 250-350 Hz. Use a narrow EQ cut in this range on individual tracks that sound boxy or cloudy, but be careful not to remove too much warmth.

How can I tell if my monitoring setup is causing me to add too much low-end?

Reference your mix on multiple playback systems like car speakers, phone speakers, and headphones. If your track sounds boomy or bass-heavy everywhere except your studio, your monitors or room acoustics are likely fooling you into adding excessive low-end.
