Mixing Drums: Kick, Snare, Hats, Room and the Kick-Bass Relationship

How to mix a drum kit that hits — frequency targets for kick and snare, transient shaping, parallel compression settings, and how to make the kick and bass share the low end.

Drums are mixed in a fixed order of importance: get the kick and snare right, fit the bass around the kick, then place everything else. Most weak drum mixes are not a plugin problem — they are a problem of two elements competing for the same 40 Hz of low end.

Kick

The frequency map:

RangeWhat lives there
40–60 HzSub weight, felt more than heard
60–100 HzFundamental punch
100–200 HzBody and warmth
300–600 HzBoxiness — usually cut 2–4 dB
2–5 kHzBeater click and definition

High-pass below 30 Hz to remove inaudible energy that eats headroom. Then choose a lane: a 60 Hz-centred kick suits hip-hop and trap, a 90–100 Hz-centred kick cuts through on laptops and in rock.

Compression on the kick should be gentle — ratio 4:1, attack 10–30 ms so the transient passes through untouched, release fast enough to recover before the next hit, 2–4 dB of gain reduction. A fast attack on a kick kills the click, which is the opposite of what most people want.

Snare

The fundamental usually sits between 150 and 250 Hz, the crack between 2 and 5 kHz, and the snare-wire sizzle above 8 kHz. Cut 400–600 Hz if it sounds cardboard-like.

Snare benefits more from compression than the kick does: ratio 4:1, attack 10–20 ms, release around 100 ms, 4–6 dB of gain reduction, which lets the tail bloom and makes the drum sound bigger.

Reverb on the snare is where the drum kit gains size. A 0.8–1.4 s plate or room with 15–30 ms pre-delay, high-passed at 300 Hz, is the standard.

Hats and cymbals

High-pass at 300–500 Hz without hesitation. There is nothing useful below that on a hi-hat, and the accumulated low-mid energy from open hats and cymbals is a common source of mix clutter.

Hats mostly need level and pan, not processing. If they sound harsh, a narrow cut around 6–8 kHz usually fixes it. Keep them a few dB quieter than feels right when soloed — hats sound loud in isolation and disappear in context far less than you expect.

Room and overheads

Room mics are the fastest route to a kit sounding like one instrument rather than four samples. Compress them hard — ratio 8:1 or higher, fast attack, 8–15 dB of gain reduction — and blend underneath. On programmed drums, a short room reverb on a send fed by kick, snare and percussion does the same job.

Transient shaping

A transient designer is often better than a compressor for programmed drums, because it works on the envelope rather than on level.

  • More attack on a soft kick or snare makes it cut through without raising its overall level.
  • Less sustain on a boomy kick tightens the low end more cleanly than an EQ cut.
  • More sustain on a dry sampled snare adds body without reverb wash.

Parallel compression

Send the whole kit to a parallel bus. On that bus: ratio 10:1 or higher, attack around 1–10 ms, release fast (30–100 ms), 10–20 dB of gain reduction. Then blend it in underneath the dry kit until the drums feel bigger, usually at a level where muting the parallel bus makes the kit sound noticeably smaller but you cannot pick the bus out.

Because the dry kit is untouched, you keep the transients and gain the body. This is why the technique is called New York compression.

The kick and bass relationship

This is the decision that makes or breaks the low end.

  1. Find the kick fundamental. Use a spectrum analyser, or sweep a narrow boost until the weight peaks.
  2. Put the bass somewhere else. If the kick peaks at 60 Hz, aim the bass energy at 90–110 Hz, and cut a 2–3 dB notch in the bass at 60 Hz.
  3. Add dynamic separation. Sidechain the bass from the kick with 3–6 dB of ducking, or duck only the sub band with a dynamic EQ.
  4. Check in mono, on a small speaker. If the kick disappears, you have a phase or masking problem, not a level problem.

Frequently asked questions

What frequencies should I boost on a kick drum?

The weight sits between 50 and 80 Hz, the body around 100 to 200 Hz, and the beater click between 2 and 5 kHz. Cutting around 300 to 500 Hz removes boxiness. Which of those you boost depends on the genre and the speakers your listeners use.

What is parallel compression on drums?

You send the drums to a duplicate bus, compress that bus heavily with a high ratio and 10 to 20 dB of gain reduction, then blend it under the untouched original. You gain body and sustain while keeping the original transients intact.

How do I stop my kick and bass fighting?

Give each one a different centre frequency. If the kick peaks at 60 Hz, tune the bass to sit around 90 to 100 Hz, and cut a narrow notch in the bass at the kick frequency. Adding a few dB of sidechain ducking on the bass finishes the job.
