Cut-Through EQ

Make it sit, not just loud.

How band EQ shaping lets any instrument cut through a voice, dodge the mud, and stay individually clear — from a deep research pass on frequency bands, masking, and per-instrument recipes.

The Map

The frequency bands — what each one controls

Every instrument has a home in specific bands, and every band has a job. Knowing the map is the difference between guessing and deliberately shaping a source.

Golden rule: cut before you boost. Cutting overlapping frequencies is almost always cleaner than boosting the other signal.

The Problem

Frequency masking — why instruments get lost

When two sounds occupy the same frequency range at once, the louder one makes the quieter one hard — or impossible — to hear. A muddy mix and a buried vocal are almost always masking.

How EQ creates cut-through, clarity & de-mud

Cut-through isn't automatically louder — it's about giving each instrument an unshared slice of the spectrum, then shaping character.

Per Instrument

A recipe for every source

The 8 sources from the AudioMix guide: fundamental range, high-pass point, cuts to de-mud, boosts to cut through, and how to place each against the lead vocal.
