EQ, Compression & Reverb
Three tools, three completely different jobs: shaping tone, taming dynamics, and adding space — and most mixes lean on all three.
EQ: shaping tone by frequency
EQ (equalization) boosts or cuts specific frequency ranges. Cutting muddy low-mids can clean up a cluttered mix; boosting a vocal's upper range can add clarity and presence. EQ doesn't change how loud or dynamic a sound is — only its tonal color.
Compression: evening out dynamics
Compression reduces a signal's dynamic range — the gap between its loudest and quietest moments — by automatically turning down the loud peaks. The result is a more consistent, often punchier sound, since quieter details stay audible instead of getting buried by the occasional loud hit.
Reverb: adding space
Reverb simulates the natural reflections of a physical space — a small room, a hall, a cathedral — around a dry recording. It adds depth and a sense of "glue" that helps separately recorded parts feel like they're happening in the same place together.
Common questions
What does EQ do?
Boosts or cuts specific frequency ranges to shape a sound's tone, remove clutter, or make room for other instruments.
What does compression do?
Evens out a signal's dynamic range, giving it more consistency and often more punch.
What does reverb do?
Simulates the natural reflections of a physical space, adding depth and a sense of glue to a mix.
Do you always need all three?
No — they're applied as needed, depending on what a particular recording or mix is missing.
