Compression Techniques

Compression is one of the most misunderstood tools in production. Learn to use it properly for punch, consistency, and glue without squashing the life out of your tracks.

Understanding Compression Parameters

ParameterWhat It DoesUKG Starting Point
ThresholdLevel where compression startsSet so gain reduction happens on peaks
RatioHow much compression is applied2:1-4:1 for subtle, 6:1+ for aggressive
AttackHow fast compression kicks inFast (1-10ms) for control, slow (30ms+) for punch
ReleaseHow fast compression lets goTime to groove - usually 50-200ms
KneeHard vs soft transitionSoft for vocals/pads, hard for drums

Compression on Drums

Drum Compression Settings

Kick Drum

  • Ratio: 4:1
  • Attack: 10-30ms (let click through)
  • Release: 100-150ms
  • Gain reduction: 3-6dB

Snare

  • Ratio: 3:1-4:1
  • Attack: 5-15ms
  • Release: 80-120ms
  • Gain reduction: 4-8dB

Compression on Bass

Bass compression is about consistency - keeping the level steady so it sits in the mix:

  • Ratio: 3:1-6:1
  • Attack: 20-50ms (preserve the initial transient)
  • Release: Time to the groove (usually 100-200ms)
  • Gain reduction: 4-8dB on peaks

Parallel Compression

Blend heavy compression with your dry signal for punch without losing dynamics:

Parallel Compression Setup

  1. Send drum bus to a parallel channel
  2. Apply aggressive compression (10:1, fast attack, fast release)
  3. Bring the compressed signal up underneath the dry signal
  4. Blend to taste (start at 30-40%)

Multiband Compression

Control different frequency ranges independently:

  • Low band (20-200Hz): Tame boomy bass without affecting highs
  • Mid band (200Hz-2kHz): Control body and warmth
  • High band (2kHz+): Tame harsh frequencies

Summary

Compression is about control, not destruction. Use it to tame peaks, add consistency, and glue elements together. Start with gentle settings and increase until you hear the compression working - then back off slightly. Your ears are the final judge.

Devil's Advocate

Advanced thinking for experienced producers

"Is compression overused in modern music?"

The loudness war has led to over-compressed masters. Sometimes the most impactful thing is to use less compression and preserve dynamics.

Alternative Workflows to Try

  • 1.Use volume automation instead of compression for level control
  • 2.Try limiting only on peaks rather than constant compression
  • 3.Leave headroom and let the mastering engineer handle dynamics

Critical Thinking Traps

Trap: "Everything needs compression"

Reality: Some sounds are better uncompressed.

Trap: "More compression = more punch"

Reality: Over-compression makes things flat and lifeless.

Trap: "Copy settings from tutorials exactly"

Reality: Every sound is different. Use settings as starting points.
