Automation
The recording of parameter changes over time within a DAW — volume, panning, plugin settings — that play back exactly…
Aux (Auxiliary Channel)
A secondary signal path used to route audio to a shared destination — typically a headphone mix for performers, a sen…
Bus
A signal routing path in a mixing console or DAW that combines multiple audio channels and routes them to a common de…
Bus Compression
The application of compression to a group of signals routed to a shared bus, rather than to individual tracks. Used t…
Chorus
A modulation effect that creates the impression of multiple instruments or voices by layering slightly pitch-shifted …
Convolution Reverb
A reverb processor that uses impulse responses (IRs) — recordings of real acoustic spaces or hardware reverb units — …
Delay
An effect that records an audio signal and plays it back after a defined time interval, creating one or more discrete…
EQ (Equalizer)
A tool for adjusting the level of specific frequency ranges within an audio signal. Used to correct tonal imbalances,…
Exciter
A processor that generates and adds harmonic content — typically upper harmonics — to an audio signal to increase per…
Fader Automation
Volume automation applied specifically to fader levels over time within a DAW session. Distinct from plugin parameter…
Filter
A circuit or algorithm that removes or attenuates specific frequency ranges from an audio signal. Common types includ…
Frequency Masking
A psychoacoustic phenomenon where one sound obscures another when they occupy the same or adjacent frequency ranges. …
Glue Compression
Light, transparent compression applied to a group bus or mix bus to make individual elements feel cohesive and unifie…
High-Pass Filter (HPF)
A filter that allows frequencies above a set cutoff point to pass through while attenuating frequencies below it. Use…
Impulse Response (IR)
A recording that captures the acoustic signature of a physical space or hardware device by measuring its response to …
Insert vs Send
Two fundamental signal routing approaches in mixing. An insert places a processor directly in the signal path — the e…
K-System (K-Meter)
A metering system developed by mastering engineer Bob Katz that establishes a standardized monitoring reference level…
Low-Pass Filter (LPF)
A filter that allows frequencies below a set cutoff point to pass through while attenuating frequencies above it. Use…
Master Bus
The final summing point in a mixing session where all audio channels combine before output. Processing applied to the…
Mid-Side (M/S)
A stereo processing technique that separates a stereo signal into its center content (mid) and stereo width content (…
Mix Bus
The stereo summing bus within a mix session where all tracks combine before reaching the final output or master chain…
Mono Compatibility
The quality of a stereo mix to translate accurately when collapsed to a single mono channel. Content existing only in…
Pan Pot
Short for "panoramic potentiometer." The rotary control on a mixing console or DAW channel that positions the signal …
Panning
The placement of an audio signal in the stereo field between left and right speakers. Used to create width, separatio…
Panning Law
The mathematical rule that determines how a DAW adjusts the signal level when a sound is panned between left and righ…
Phantom Center
The psychoacoustic illusion of a sound source appearing at the center of a stereo image when identical signals are re…
Pitch Correction
The process of adjusting the pitch of a recorded performance to align with the intended musical scale. Can be applied…
Plate Reverb
A reverb type that uses a large suspended metal plate to create reverberation. An audio transducer vibrates the plate…
Pre-delay (Reverb)
A short delay applied before the onset of reverberation. Allows the direct signal to be heard clearly before the reve…
Q Factor (Bandwidth)
A parameter in parametric equalizers that controls the width of the frequency band being boosted or cut. A high Q val…
Reverb (Room)
A reverb simulation designed to replicate the acoustic characteristics of a small-to-medium room rather than a large …
Reverberation (Reverb)
The persistence of sound in a space after the source has stopped, created by multiple reflections off surfaces. In mi…
Saturation
A form of harmonic distortion that adds warmth, density, and character to audio signals. Originally a byproduct of an…
Send / Return (FX Bus)
A routing configuration in which a portion of a channel's signal is sent to a shared effects processor — such as a re…
Sibilance
Harsh, high-frequency sounds produced by consonants such as "s," "sh," "t," and "ch" in vocal recordings. Excessive s…
Sound Design
The creative discipline of creating, manipulating, and arranging audio elements to serve a narrative, aesthetic, or f…
Stereo Bus
The final two-channel summing point in a mix where all tracks and buses combine before reaching the monitoring system…
Stereo Width
The perceived breadth of the stereo image in a mix. Narrow mixes sound focused and mono-compatible; wide mixes create…
Subgroup
A routing configuration in which multiple related channels are grouped together and routed through a shared bus befor…
Summing
The mathematical and electrical process of combining multiple audio signals into a single output. In digital audio, s…
Tail (Reverb Tail)
The decaying portion of a reverb that follows the initial reflections. The length and character of the tail determine…
Tape Emulation
A plugin or hardware unit that replicates the sonic characteristics of analog tape recording — saturation, harmonic d…
Vocal Chain
The specific sequence of processors applied to a lead vocal, typically including EQ, compression, de-essing, and satu…
Wet/Dry Ratio
The balance between the processed (wet) signal and the unprocessed original (dry) signal when using an effect. A high…
