How to compress a kick drum

For most kick drums, set threshold around −12dB, ratio 4:1, attack 5ms, release 60ms.

Updated 2026-05-02

Short answer

For most kick drums, set threshold around −12dB, ratio 4:1, attack 5ms, release 60ms. The fast attack catches transients without killing them; the medium release lets the kick breathe between hits.

Threshold: −12 dB, start so it catches the loudest hits
Ratio: 4:1, moderate, audible but not crushing
Attack: 5 ms, slow enough to keep the click
Release: 60 ms, fast enough to fully recover before the next kick
Knee: 6 dB, soft knee for a smoother feel

Set the threshold first

Pull the threshold down until the gain reduction meter shows 4–6dB on the loudest hits. For a normal mix, that usually lands around −12dB. Too high (−6dB) and the compressor barely engages; too low (−24dB) and you're squashing every transient flat.

Pick a moderate ratio

4:1 is the sweet spot for kicks. It's audible enough to glue and shape the sound but not so aggressive that the kick loses energy. Higher ratios (8:1, 10:1) work for parallel/aggressive compression on a duplicated bus, not on the main channel. Below 3:1 and you barely hear the effect.

Attack: slow enough to keep the click

The attack on a kick is roughly the first 5–15ms, that's where the click and snap live. If your attack is too fast (1ms), the compressor clamps down on the transient and the kick goes flat. Start at 5ms. If the kick still loses click, push to 10–15ms. Listen for the punch, not the meter.

Release: fast enough to recover

At 128 BPM, four-on-the-floor kicks land every ~470ms. The compressor needs to fully release before the next hit or you'll get pumping that wasn't musical. 60ms is a safe starting point, fast enough to recover, slow enough to feel natural. For slower BPMs, you can go up to 100–120ms.

Frequently asked

What ratio should I use to compress a kick drum?

4:1 is the standard starting point. It's audible but not aggressive. Higher ratios (8:1+) work for parallel compression on a duplicated bus. Below 3:1 the effect is usually too subtle to be worth the CPU.

Should attack be fast or slow on a kick?

Slow enough to let the transient through, usually 5–15ms. A fast attack (1ms) clamps down on the click and makes the kick sound dull. The first 5ms of a kick is the punch; you want to preserve it.

Why is my kick drum pumping?

The release is too long for the tempo. The compressor hasn't recovered before the next hit, so it's still reducing gain when the next kick arrives. Drop release to 40–80ms or use a release-tied-to-tempo mode if your compressor has one.

Should I compress a kick before or after EQ?

Usually after subtractive EQ (cuts) and before boosts. The compressor reacts to a cleaner signal once the muddy frequencies are cut, and any boosts after compression don't get squashed. A common chain: HP → mud cut → compress → presence boost.
