Automation
Automation records time-varying parameter changes so every fader move, mute, and effect tweak plays back identically on every mix pass.
→
Aux Send
The channel-level control that routes a signal copy to a shared bus for parallel effects, monitor mixes, and group processing.
→
Bus
A bus is a shared signal pathway that routes multiple tracks to a single channel for collective processing, grouping, and control.
→
Bus Compression
Bus compression unifies grouped tracks or a full mix by gently controlling collective dynamics — the technique behind the 'glue' sound in professional
→
Fader
The fader is the central level control of any mix — a sliding attenuator that defines balance, dynamics, and final output.
→
Frequency Masking
Frequency Masking is the psychoacoustic effect where loud frequencies suppress the perceived loudness of quieter nearby frequencies in a mix.
→
Gain
Gain controls signal amplitude at every stage of the chain — the foundational skill separating professional mixes from amateur ones.
→
Gain Reduction
Gain Reduction is the dB attenuation a compressor or limiter applies when a signal crosses the threshold.
→
Gain Staging
Gain Staging is the discipline of optimizing signal levels at every stage of the signal chain to eliminate clipping and noise.
→
Gain Structure
The art of calibrating every stage of your signal chain so noise stays buried and headroom stays open.
→
Glue
Glue is the mix quality that makes separate tracks feel like one unified recording, typically achieved via bus compression or saturation.
→
Loudness Matching
Loudness Matching ensures volume-matched comparisons so louder never means better in your mix decisions.
→
Makeup Gain
Makeup Gain restores output level lost to gain reduction — the essential final step in any compression chain.
→
Mid-Side EQ
Mid-Side EQ processes center and side channels independently for surgical control over stereo width and frequency balance.
→
Mid-Side Processing
Mid-Side Processing splits stereo audio into center and width components for independent EQ, compression, and spatial control.
→
Mix Bus
The mix bus is the master stereo summing channel where every track converges before the final output.
→
Mix Translation
Mix Translation is how consistently your mix sounds across every playback system your audience will ever use.
→
Mono Compatibility
How to ensure your stereo mix survives mono playback without phase cancellation, level loss, or tonal collapse.
→
Panning
Panning positions audio signals across the stereo field, creating separation, width, and perceived depth in a mix.
→
Parallel Processing
Blend a dry source with a heavily processed copy to add density, color, or energy without sacrificing transients.
→
Phase
Phase describes a wave's cycle position relative to another — misalignment causes cancellation that silently ruins low end and transients.
→
Reference Track
A commercially released song used as a sonic benchmark to calibrate frequency balance, loudness, and dynamics during mixing.
→
Send & Return
The parallel routing architecture that lets multiple tracks share a single effect while preserving every dry signal intact.
→
Space
Space defines the three-dimensional environment of a mix through reverb, delay, panning, and EQ — the difference between flat and immersive.
→
Stem
A stem is a grouped, pre-mixed audio export representing one section of a track — drums, bass, synths, vocals — used in mixing, mastering, and licensi
→
Stereo Imaging
Stereo imaging shapes how wide, deep, and spatially convincing your mix sounds across the left-right stereo field.
→
Stereo Width
Stereo Width defines how far a sound spreads across the left-right field — the foundational spatial parameter in mixing.
→
Summing
Summing combines multiple audio signals into one output — the foundational process behind every bus, mix, and master in audio production.
