Glossary

79 terms collected from across this guide. Updated automatically as chapters are written.

Abbey Road Technique

Using reverb on the snare (and sometimes only the snare) to create a sense of space for the entire drum kit, relying on the ear to fill in the gaps. Ch. 7

Acoustic Treatment

Physical modifications to a room (panels, bass traps, diffusers) that control how sound behaves at the listening position — not soundproofing, but sound management. Ch. 1

Archive vs. Backup

A backup is a working copy for mid-project recovery; an archive is the final packaged session stored for long-term safekeeping — conflating the two causes problems. Ch. 18

Automation

Writing parameter changes over time in the DAW's timeline — volume, panning, send levels, plugin parameters — so the mix becomes a performance rather than a static balance. Ch. 15

Bus (Submix)

An auxiliary channel that multiple tracks are routed through before reaching the master, giving you single-fader control over an instrument group and a place to apply group processing. Ch. 3

Chorus

A modulation effect that duplicates and slightly detunes and delays the signal to create a thicker, wider, shimmering version of the original. Ch. 9

Clip Gain

Adjusting the level of an audio region at its source before it hits any processing, the most transparent way to control dynamics. Ch. 2

Clip Gain Editing

Normalizing the level of individual vocal phrases before the processing chain so the compressor receives a more consistent signal and sounds more transparent. Ch. 14

Committing (Printing)

Rendering MIDI instruments and effects to audio tracks, which freezes sound choices, reduces CPU load, and gives you visual waveforms to work with. Ch. 3

Compression

Reducing dynamic range by turning down parts that exceed a threshold — an automatic fader that reacts to level, not to tone or musicality. Ch. 5

Contrast

The principle that automation's power is relative — a chorus sounds big because the verse was quiet, a throw sounds dramatic because the vocal was dry. Ch. 15

Convolution Reverb

A reverb that uses a recorded impulse response of a real acoustic space to simulate its characteristics, sounding extremely realistic but less tweakable than algorithmic reverbs. Ch. 7

Damping

How quickly high frequencies decay within a reverb tail — high damping produces a darker tail that sits behind the mix more easily. Ch. 7

De-esser

A frequency-targeted compressor that reduces vocal sibilance (the harsh s, sh, and ch sounds) by compressing a narrow band around 4-10 kHz. Ch. 6

Decorrelation

Making the left and right channels slightly different from each other through reverb, chorus, or other stereo effects to create width from a mono source. Ch. 10

Delta Monitoring

Listening to only the difference between processed and unprocessed signal to reveal exactly what your processing is adding or removing. Ch. 17

Diffusion

How quickly early reflections blur into a smooth reverb tail — high diffusion yields a dense, smooth decay while low diffusion reveals individual reflections. Ch. 7

Dither

Low-level noise added when reducing bit depth (e.g., 24-bit to 16-bit) to preserve low-level detail that would otherwise be truncated — handled by the mastering engineer, not the mixer. Ch. 18

Doubled Guitars

Two separate performances of the same part panned hard left and right, where micro-variations between takes create genuine stereo width. Ch. 13

Dynamic EQ

An EQ that only activates when a specific frequency band exceeds a threshold, more transparent than static EQ for intermittent problems. Ch. 4

Ear Candy

Small, surprising moments in a mix that reward close listening — a filter sweep, a reversed cymbal, a momentary pitch effect — essential to the experience but not the song structure. Ch. 15

Expander

A gentler alternative to a gate that reduces signals below the threshold proportionally rather than silencing them abruptly. Ch. 6

Fader Creep

The gradual tendency to push all faders up over the course of a session, eliminating headroom and flattening dynamics. Ch. 1

Feedback

A delay parameter controlling how many times the signal repeats — low feedback yields one or two fading repeats, high feedback creates cascading trails. Ch. 8

Fletcher-Munson Curves

Equal-loudness contours showing that human hearing is less sensitive to bass and treble at low volumes, flattening out around 85 dB SPL where you hear the most balanced frequency response. Ch. 1

Frequency Pocket

A defined range in the frequency spectrum where an instrument's core character lives, carved with EQ so it does not compete with other instruments. Ch. 13

Gain Staging

Managing signal levels through every point in the chain — source, input trim, plugins, fader, bus, master — so nothing clips and every processor receives signal at the level it expects. Ch. 3

Gate Range/Floor

A gate parameter that reduces level by a set amount when closed rather than silencing completely, preserving some natural bleed. Ch. 6

Haas Effect (Precedence Effect)

When two identical sounds arrive within about 1-30ms of each other, the ear perceives them as a single source located at the earlier arrival — used to create width from a mono source. Ch. 8

High-Pass Filter (HPF)

A filter that cuts everything below a set frequency, removing low-end content that does not belong on a track — the most-used filter in mixing. Ch. 4

K-System

Bob Katz's metering standard that ties SPL calibration to meter reading, creating a fixed relationship between what you see on the meter and what you hear in the room. Ch. 16

Knee

Controls how a compressor transitions into gain reduction at the threshold — hard knee engages abruptly, soft knee eases in gradually. Ch. 5

LCR Panning

A mixing approach where everything is panned hard left, center, or hard right with nothing in between, forcing maximum separation and clear placement decisions. Ch. 10

Level Matching

Pulling the mastered reference track down to match the perceived loudness of your unmastered mix so you compare tonal balance and dynamics rather than volume. Ch. 17

LFO (Low-Frequency Oscillator)

A slow-moving wave that modulates a parameter up and down over time, controlling the rate and depth of modulation effects. Ch. 9

Limiter

A compressor with a very high ratio (typically infinity to one) and very fast attack that prevents any signal from exceeding the threshold. Ch. 5

Low-End Management

Dividing the sub-bass and bass frequency ranges between the kick drum and bass instrument so they complement rather than compete. Ch. 12

LUFS

Loudness Units Full Scale — a perceptually weighted loudness measurement used by streaming platforms for normalization, with Momentary (400ms), Short-term (3s), and Integrated (full program) windows. Ch. 16

LUFS Targets

The loudness normalization standards used by streaming platforms — Spotify at -14 LUFS, Apple Music at -16 LUFS, YouTube at -14 LUFS — mastering louder than the target just loses dynamic range. Ch. 18

Macro/Micro Perspective

The practice of shifting listening focus between the big picture (holistic), broad strokes (macro), and fine details (micro) to avoid getting stuck at one zoom level. Ch. 2

Masking

When two instruments occupy the same frequency range and neither is clearly audible, fusing into a smeared blob instead of distinct sounds. Ch. 4

Mid-Side Processing

Separating a stereo signal into mid (center) and side (difference) components for independent processing, giving precise control over width without affecting balance. Ch. 10

Modulation Effects

Effects that duplicate a signal and vary something about the copy over time (pitch, timing, or both) using an LFO, then blend it with the original — includes chorus, flanger, and phaser. Ch. 9

Multiband Compression

A compressor that splits the signal into frequency bands and compresses each independently, allowing surgical control of problem frequencies without affecting the rest. Ch. 12

Order of Operations

The hierarchy of mixing tools from most fundamental to most refined: clip gain, then plugins, then faders, then automation. Ch. 2

Overheads-First Approach

Building the drum mix starting from the overhead mics (the most complete picture of the kit) and adding close mics for detail, rather than building from kick and snare up. Ch. 11

Overworked Mix

A mix processed past the point of improvement where cumulative EQ, compression, and saturation make it sound small and lifeless rather than polished. Ch. 17

Pad Management

Aggressively high-passing and low-passing synth pads so they fill harmonic space without competing with lead instruments in their core frequency ranges. Ch. 13

Pan Law

The gain compensation applied to signals panned to center, typically around -3 dB, which causes center-panned elements to sound quieter in headphones than on speakers. Ch. 1

Parallel Compression

Blending a heavily compressed copy of a signal with the uncompressed original, bringing up quiet details while preserving natural dynamics and transients. Ch. 5

Phase (Drums)

When multiple mics capture the same hit from different distances, the time differences cause frequencies to cancel or reinforce when summed — the first problem to solve in any drum mix. Ch. 11

Phase Correlation Meter

A meter showing the phase relationship between left and right channels, ranging from +1 (mono-compatible) to -1 (out of phase, will cancel in mono). Ch. 16

Polarity vs. Phase

Polarity is a simple waveform inversion (a button flip); phase is a continuous time-based relationship between waveforms that requires track nudging to fix. Ch. 11

Pre-delay

The gap between the dry sound and the onset of reverb, which separates the source from its reflections and maintains clarity and intelligibility. Ch. 7

Prosody

The relationship between lyrics and how they are delivered — emphasis, phrasing, rhythm of speech — which tells you which words carry the emotional weight of each line. Ch. 14

Proximity Effect

A bass boost caused by close-miking, especially common on acoustic guitars and vocals, typically removed with a high-pass filter. Ch. 13

Q (Bandwidth)

How wide or narrow a bell-shaped EQ curve is — high Q for surgical cuts on specific problems, low Q for broad tonal shaping. Ch. 4

Reference Track

A professionally mixed and mastered song you know well, loaded into the session at matched loudness to calibrate your ears and benchmark your mix. Ch. 1

Sample Augmentation

Layering triggered samples underneath live drums for consistent weight and attack, blending so the samples support rather than replace the live performance. Ch. 11

Saturation

Gentle harmonic distortion simulating analog hardware being pushed, adding warmth (even-order harmonics) and edge (odd-order harmonics) along with perceived loudness without increasing peak level. Ch. 9

Serial Compression

Using two or more compressors in sequence, each doing moderate work, so neither is pushed hard and the result sounds more natural. Ch. 5

Serial Compression (Vocal Chain)

Using a fast compressor to catch peaks followed by a slow compressor to even dynamics, each doing moderate work so the vocal sounds controlled without sounding compressed. Ch. 14

Serial vs. Parallel Routing

Serial routing passes a signal through processors in sequence; parallel routing sends copies to multiple processors simultaneously and blends the results. Ch. 3

Sidechain

Routing a different signal to a dynamics processor's detection circuit so it listens to one signal but acts on another. Ch. 6

Sidechain Compression (Kick/Bass)

Routing the kick drum to the bass compressor's detection circuit so the bass ducks briefly on each kick hit, clearing space for the kick's attack. Ch. 12

Slapback Delay

A single fast repeat at 60-120ms with no feedback, adding thickness and presence without audible echo. Ch. 8

Stem Mastering

Delivering separate submix stems (drums, bass, vocals, etc.) to the mastering engineer so they can process and balance each group independently. Ch. 18

Stereo Width

How much of the left-to-right panorama a sound occupies, created by differences between left and right channels — different performances, timing, or frequency content. Ch. 10

The Hallway Test

Walking out of the room during playback to strip away detail and hear only the broadest picture of the mix — energy, balance, and overall tone. Ch. 17

Throw

A momentary burst of delay or reverb on a specific word or note, created by automating the send level to jump up for one moment then cutting it. Ch. 8

Top-Down Automation

Automating at the bus and master level first (broad energy shifts between sections) before going to track-level detail like vocal rides. Ch. 15

Transient Designer

A dynamics processor that controls attack and sustain independently without using a threshold, reacting to waveform shape rather than level. Ch. 6

Translation (Bass)

How well the bass is audible across different playback systems — small speakers lose the fundamental, so upper harmonics must carry the perception of the bass note. Ch. 12

True Peak

The actual peak level of a signal including inter-sample peaks that occur between digital samples, caught by oversampling — set your limiter ceiling using true peak to avoid clipping on conversion. Ch. 16

Vibrato vs. Tremolo

Vibrato modulates pitch (the note wavers up and down), while tremolo modulates volume (the sound pulses louder and softer rhythmically). Ch. 9

VIP Range

The frequency band between roughly 200 Hz and 4 kHz where most musical information lives and where clarity is won or lost. Ch. 4

Virtual Soundstage

The imagined three-dimensional space of the finished mix — where each instrument lives in terms of left-right, front-back, and frequency range — used as a target before you start building. Ch. 2

Vocal Ride

Automating the vocal fader phrase by phrase so every line sits at the right level in context, the most time-consuming and most important part of vocal mixing. Ch. 14

VU Meter

A meter with a 300ms response time that measures average signal level, closer to perceived loudness than peak metering and useful for gain staging analog-modeled plugins. Ch. 16
