Customize Pipeline Settings Step Four: What Actually Matters

Most explanations of this start with a definition and stop before they get to the part that affects your session.

This covers customize pipeline settings step four the way it actually works in a session: the mechanism, the numbers that matter, and the decisions that follow from them.

Nothing below is theory for its own sake. Every number here is one you can check on a meter, and every step is one you can run on the next track you open.

Key takeaways

Balance with faders before you reach for a plugin.
Cut to solve problems, boost to flatter, and know which you are doing.
Check in mono early and often.
Leave 3 to 6 dB of headroom for mastering.

Start with balance, not plugins

Most mix problems are level problems wearing a costume. Before a single plugin, get a static balance with faders alone that already sounds like the record you want.

If the vocal will not sit with the fader, no compressor is going to fix that relationship. It will just make the problem louder and more consistent.

Set the loudest element first, usually the drums or the lead vocal, and build around it.
Work at a low monitoring level. Balance decisions made loud do not survive quiet playback.
Get the arrangement out of its own way. Removing a part beats EQing two parts that fight.
Only then start processing, and only where you can name the problem you are solving.

The frequency ranges that decide whether a mix is clear or muddy.

EQ: subtract before you add

Cutting is surgery, boosting is flattery. Both have a place, but cutting solves problems while boosting mostly moves them.

Range	What lives there	Common move
20 to 60 Hz	Sub weight and rumble	High-pass everything that is not bass or kick
60 to 120 Hz	Fundamental weight and power	Where kick and bass have to share, not stack
200 to 500 Hz	Boxiness and mud	The most common corrective cut in any mix
1 to 3 kHz	Presence and attack	Crowded. Carve here to make room for vocals
3 to 6 kHz	Definition and harshness	Small moves. Ears are most sensitive here
8 kHz and up	Air and sibilance	Broad shelf lifts, narrow cuts for sibilance

Frequency masking is the underlying problem. Two sources competing in the same band make each other quieter. Carving one and leaving the other alone works better than boosting both.

Compression with a purpose

Every compressor setting should answer a question. If you cannot say what the compressor is doing, it is probably doing damage.

Type	Circuit	Attack range	Character
VCA	Voltage-controlled amplifier	20 microseconds to 30 ms	Clean, fast, predictable. The SSL bus compressor is the archetype: 2:1...
FET	Field-effect transistor	20 to 800 microseconds	Fast and aggressive. The 1176 is the reference. Use it for vocal and d...
Opto	Optical	10 ms, programme-dependent	The LA-2A slows down as it works, which is why it flatters vocals. You...
Vari-Mu	Variable-mu tube	Programme-dependent	The Fairchild lineage. Ratio rises with input level, so it self-regula...

Attack controls how much transient survives. Slower keeps the punch, faster tames it.
Release controls the groove. Set it so the gain reduction meter moves with the tempo.
Ratio decides whether you are levelling (2:1 to 4:1) or limiting (8:1 and up).
Gain reduction of 3 to 6 dB on a source is normal. 15 dB is a decision, not a default.

Check it where people will hear it

Mono, first and often. Phase problems and width tricks both collapse here.
A single small speaker, to check that the midrange carries the song.
Headphones and earbuds, because that is where most listening happens.
In a car, which is still the most honest low-end test most people have access to.
Quietly. A mix that works at conversation volume works everywhere.

The mistakes that cost the most

These are not exotic. They are the five things that show up again and again in tracks that almost work.

Judging at a different level each time. Loud always sounds better, so set a monitoring level and leave it.
Solving a balance problem with a plugin. If the fader cannot fix the relationship, a compressor will only make the wrong balance more consistent.
Working only on one system. A mix that only holds together on your monitors is not finished, it is calibrated to your room.
Boosting where you should be cutting. Making something louder to beat a masking problem raises the whole noise floor of the arrangement.
Never bypassing. If you have not compared against the unprocessed version in the last twenty minutes, you have lost your reference point.

Take a break every forty minutes. Ear fatigue does not announce itself, it just quietly moves your idea of what bright means.

Knowing when to stop

There is a point in every session where further work stops improving the record and starts merely changing it. Recognising that point is most of the skill.

You are undoing changes as often as you are making them.
You cannot articulate what the last move fixed.
The reference no longer sounds obviously better in any specific way.
You are adjusting things you would not notice as a listener.

Bounce it, sleep on it, and listen once in the morning on a system you did not use to make it. That single listen tells you more than another two hours ever will.

Frequently asked questions

What is the most important thing to get right with customize pipeline settings step four?

Tonal balance and translation. A track that holds up on a phone, in a car and on monitors is finished. One that only works on your monitors is not.

What loudness should I target?

-14 LUFS integrated with a -1 dBTP ceiling covers almost all streaming. Go quieter for acoustic and classical material, louder only where the genre genuinely demands it.

How much headroom should the mix have?

Three to six decibels, with no limiter on the mix bus. That gives the mastering stage something to work with.

How do I know when it is finished?

When it holds up level-matched against a commercial reference, translates on several systems, keeps its low end in mono, and your changes have stopped improving it.
