Quick Recipes: Directional EQ Settings for Vocals, Drums, and Guitars

Directional EQ lets you apply different equalization to signals based on their stereo position or the direction of arrival in an imaging context. Instead of a single static EQ curve, directional EQ enables you to shape frequency content differently for center-versus-side, left-versus-right, or even frequency-dependent spatial placement. Below are concise, practical recipes for vocals, drums, and guitars that you can use as starting points. Each recipe lists the sonic goal, a suggested directional EQ approach, and specific parameter starting values — adjust by ear.

How to use these recipes

• Run the directional EQ in a “mid/side” (center vs. sides) or “left/right” mode depending on your plugin.
• Set a neutral bypass and compare A/B while making changes.
• Make subtle gains (±1–4 dB) with narrow Q for surgical cuts and wider Q for tonal shaping.
• Use high-pass filters on side channels only where noted to tighten low-end imaging.

Vocals — Make the lead sit in the center while keeping presence in the mix

Goal: Keep vocals focused and clear in the center while preserving air and stereo ambiance from reverb or doubles.

Recipe (Mid/Side):

• Mid (Center) band:
  • 150–400 Hz: gentle cut, 1–2 dB, Q 1.5 — reduce boxiness.
  • 2.5–5 kHz: slight boost, 1–3 dB, Q 1.2 — presence and intelligibility.
  • 10–12 kHz: small boost, 1–2 dB, Q 1.4 — air.
• Side (Stereo) band:
  • 200–400 Hz: cut, 1.5–3 dB, Q 1.5 — reduce muddiness in stereo ambience.
  • High-pass at 200–400 Hz (slope 12–24 dB/oct) — keep low rumble out of reverb tails.

Notes: For backing vocals, invert approach (wider boost around 1–3 kHz on sides) to increase width while keeping lead prominent.

Drums — Tighten kick/snare in center; add cymbal shimmer on sides

Goal: Keep low punch focused in the center while letting overheads/cymbals breathe on the sides.

Recipe (Mid/Side):

• Mid (Center) band:
  • 50–100 Hz: boost narrow, 1–3 dB, Q 1.2 — add kick/sub weight (watch for muddiness).
  • 200–400 Hz: cut 1–3 dB, Q 1.5 — reduce boxiness from toms/snare.
  • 3–6 kHz: boost 1–3 dB, Q 1.0 — snap and attack on snare.
• Side (Stereo) band:
  • 8–12 kHz: boost 1–3 dB, Q 1.2 — cymbal shimmer and air.
  • High-pass at 150–250 Hz — remove low-end energy from overheads to prevent phasey stereo bass.

Notes: If using drum bus after parallel compression, apply more subtle side boosts to preserve natural stereo.

Electric/Acoustic Guitars — Carve space for center elements; enhance stereo width

Goal: Prevent guitars from cluttering vocals while enhancing stereo image.

Recipe A — Mono/Centered rhythm guitar (Mid focus):

• Mid/Center:
  • 120–250 Hz: cut 1–3 dB, Q 1.4 — reduce muddiness.
  • 800 Hz–1.5 kHz: small cut 1–2 dB if conflicting with vocals.
  • 3–6 kHz: mild boost 1–2 dB for presence.
• Sides:
  • 5–10 kHz: boost 1–3 dB, Q 1.2 — add sparkle to stereo doubles.
  • High-pass at 200–300 Hz to keep low end tight.

Recipe B — Stereo double guitars (Left/Right emphasis):

• Left channel:
  • 200–500 Hz: slight cut 0.5–2 dB to avoid mud.
  • 1–3 kHz: mild boost 0.5–1.5 dB for character.
• Right channel:
  • Complementary boost/cut around 2–5 kHz (rotate center frequency relative to left by 300–800 Hz) to create separation.
• Use subtle differences in Q/gain between sides to enhance perceived width.

Notes: For acoustic guitars, gentler Qs and smaller gains (±0.5–1.5 dB) generally sound more natural.

Quick troubleshooting and refinements

• If low end becomes thin: reduce side high-pass frequency or reduce mid low cuts.
• If vocals disappear: cut competing instruments in the same band on the sides, not the mid.
• If phase issues occur: check mono compatibility and bypass mid/side processing to compare.
• Always use a final gentle master bus glue or multiband compression after spatial EQ adjustments if needed.

Short checklist before bouncing

1. A/B bypass to confirm improvement.
2. Check in mono for phase cancellation.
3. Listen at low and high volumes.
4. Automate any extreme directional EQ moves for sections that need them only.

Use these as starting points — small, musical moves work best. Adjust frequencies and Q by ear to suit the material.
