The Spectral Colors school

Learn music production, one path at a time.

Every guide on this site belongs to a route. Follow a path top to bottom and each idea builds on the one before it — no theory lectures, no filler, just the order that makes things click.

17 paths6 levels≈ 8 hours of reading

Level 1

Start here

If you are new, take these three in order. They cover writing a track, understanding the format your plugins use, and the ideas every later path assumes.

Level 2

Learn the tools

What each processor actually does, so you stop choosing them by name and start choosing them by job.

Level 3

Solve real problems

The specific situations that come up in every session, and how to deal with each one properly.

Level 4

Finish and release

Turning a mix into a record: the mastering stage, what it can and cannot do, and how to know when to stop.

Level 5

Sound design

Making the sounds instead of choosing them — synthesis, sampling, spectral processing and genre craft.

Level 6

Music Theory

Mixing Guides

Using one sound to duck another: how to make space in a mix

Space is not created by turning things up. It is created by deciding who is allowed to be loud at each moment.

EQ & Dynamics

One plugin instead of EQ plus a compressor: the dynamic EQ workflow

One plugin can carry the corrective cut, the level-dependent cut and the tonal shaping — if you set the bands in the right order.

Mixing Guides

Effects chain order: why the rack hierarchy changes your sound

Two identical plugins in a different order do not sound the same. Each one reacts to what the previous one already changed.

EQ & Dynamics

EQ: cutting vs boosting, and when each one is right

Cut to remove a problem. Boost to add something that exists but is too quiet. Neither is morally superior.

Creative Workflow

Finding your own sound

Your sound is not something you find. It is what remains after you stop removing the things that make you different.

Mastering & Low End

Fixing it in the master, or fixing it in the mix?

If the problem has a name — the vocal, the kick, the snare — it belongs in the mix. Mastering has no vocal channel.

Mixing Guides

Fixing weak mixes with EQ and sound hierarchy

A weak mix is rarely missing processing. It is missing a decision about who matters most.

4 min readRead post →
Mastering & Low End

How the pros master: what actually differs

The difference is not the gear. It is the room, the references, the restraint and the number of tracks they have heard.

Creative Workflow

Arrangement: how to keep a song interesting

Interest does not come from adding. It comes from contrast — and contrast requires taking things away.

Routing & Workflow

How to build a drum bus, step by step

Route it, balance it, then add one processor at a time — and make each one earn its place.

Mastering & Low End

What makes a good mastering chain, and how to build one

A good mastering chain is short, ordered, and every stage has a job you can say out loud.

Mixing Guides

Creating space in a mix: the four dimensions

Every element needs somewhere to be. There are four places to put it, and most mixes only use one.

Mixing Guides

Muddy reverb? This is how to use it the right way

Reverb does not make a mix muddy. Unfiltered, undelayed, undicked reverb does.
