How to Fix a Muddy Mix
Mud usually lives between 200 Hz and 500 Hz, where vocals, low guitars, low keys, and the top of the bass all collide. Here is how to clean it up before mastering.
Identify the mud
Solo each element and sweep a narrow boost between 200–500 Hz. Anything that sounds boxy, thick, or congested is a candidate for a small cut.
High-pass everything that isn't bass
High-pass non-bass elements (vocals, guitars, keys, FX) between 80–150 Hz to free the low-mids for the kick and bass.
Carve space with subtractive EQ
Cut 2–4 dB at the muddy frequency on competing elements. Subtractive EQ almost always sounds more natural than boosts.
Control low-end dynamics
Use a fast compressor on bass and kick to keep low-end energy steady — uneven low-end reads as mud on small speakers.
Re-export and re-master
Bounce a fresh 24-bit WAV with -6 dBFS headroom and run it through FNLZ Studio. A clean mix masters cleanly.
Frequently asked questions
Why does my mix sound muddy on Spotify?
Streaming compression amplifies low-mid buildup. Cleaning 200–500 Hz before mastering keeps the track clear after platform processing.
Can mastering fix a muddy mix?
Mastering can reduce mud, but it cannot fully fix mix-stage problems. Cleaning the mix first always produces a better master.
