Equalizing
the use of filters for cutting or boosting selected frequencies
Exciter/Enhancer
device or program for improving treble and bass intelligibility
Expander
(see Noise Gate)
Fader
linear potentiometer with logarithmic response
Feedback (howlround)
unstable circuit (e.g. mic/speaker, input/output) where a signal is able to return to an input from an output,
causing successive cycles of progressively higher gain (avoid it by e.g. not using a mic close to a speaker
driven from the mics own signal)
Filter
device or program for adding or removing removing part of frequency bandwidth e.g. for dramatic effect
Flanger/Chorus
device or program for adding short modulated echoes
Gain
degree of amplification
Headroom
signal range between nominal level and clipping
Incoming (cue) track
music being auditioned prior to being played
Kill Switches
switches for removing frequency bands
Limiter
(see Compressor)
Line level signals
signals from low impedance sources (-10 to +6 dBu)
Lo(w) Cut (= High Pass) Filter
cuts off low frequencies
MCing
adding dialog to a sequence of music
MIDI
Musical Instrument Digital Interface - the language used by 99% of all electronic musical devices and programs
Mixdown
process by which a multitrack recording is combined into e.g. one or two channels
Mixing
seguing music to form continuous flow
Mute
(to engage) button for signal muting
Mute Switch
(see Cut Switch)
Noise Gate
device or program for auto-muting
Normal
connect an output to an input via breakable link
Outgoing (mix) track
music currently playing
Parametric EQ
EQ whose frequency can be swept e.g. for dramatic effect
PFL
Pre-Fader-Listen
Phantom Power
+48 V DC voltage for powering condenser mics
Phase coherence
degree to which L & R signal are synchronized
Phase correlation
degree of mono compatibility of L & R signal
Pot or potentiometer
a variable, usually rotary voltage driver used e.g. for gain, frequency, quality or bandwidth control
