What it’s for

Example settings for vocals, bass and drums.

Vocal level control

Use clip gain to reduce large differences between phrases. Lower Threshold to compress the remaining peaks by a few dB, then check the quieter sections.

Starting point

Threshold
Just below the loud lines
Ratio
4:1
Attack
10 ms
Release
120 ms

Bass compression

Reduce differences between bass notes with a slower Attack to retain the initial pluck. Use the kick as a sidechain input if you want the bass level to dip on each kick hit.

Starting point

Ratio
4:1

30 ms

Sidechain
Off, or the kick

Drum bus compression

Start with a low ratio and slow attack to reduce loud hits while retaining transients. Adjust Release so the gain recovers between hits.

Threshold
Only the loudest hits

The controls

Planned controls and suggested starting settings for a vocal.

Left knob

Attack

How quickly it clamps down once a sound crosses the threshold. Fast catches the very front of a word or a drum hit, which can sound dull. Slower lets that first edge through before it reacts, so drums keep their punch and consonants stay clear.

Start at10 ms

Centre knob

Threshold

The level where compression begins. Anything louder gets turned down, anything quieter passes untouched. Lower it and more of the track gets caught: the loud parts come down and the whole thing sounds more even, then flatter if you keep going.

Start at−18 dB

Right knob

Release

How quickly gain returns after the signal drops below Threshold. A short release can cause audible pumping; a long release can keep the next phrase compressed.

Start at120 ms

Left menu

Ratio

How firmly the level is turned down once it’s over the threshold. At 4:1, a line that goes 8 dB over comes out only 2 dB over. Lower ratios are gentle and easy to miss. Higher ones hold the level almost flat.

Start at4:1

Middle menu

Character

The flavour of the compression, separate from how much of it there is. Start on Clean, where the aim is a steadier level rather than a different tone.

Start atClean

Right menu

Sidechain

Set to Off, the track’s own level decides when it gets turned down. Point it at another track, like the kick, and that track decides instead: the bass dips each time the kick lands, so the two stop crowding each other.

Start atOff

Compression tips

Check loud and quiet phrases while setting the compressor.

Loop the loudest line
Find the loudest phrase in the song and loop it. Lower Threshold until it comes down a few dB, then play the quietest phrase and check that it passes through untouched.
Overdo it first
Not sure what Threshold is catching? Set Ratio high and Attack fast for a moment, so the squeeze is obvious. Once you can hear which notes are being pulled down, bring both back to where they sound natural.
Tame the big jumps
When a vocal goes from a whisper to a full belt, no single setting handles both without squashing something. Turn the loudest lines down first with clip gain or a volume ride, then let Compressor even out what’s left.
