repeats within one second.
Fricative: A consonant, such as 'f' or 's' , produced by the

Gain: Another term for signal level.
Gain reduction (compressor): Decrease in gain when
input signal is above threshold. See Gain.
GEQ: Abbreviation for 'graphic equaliser' . See Graphic EQ.
GEQ rack: A virtual rack of GEQs. See Virtual rack.
Granularity: A measure of the size of components or a
description of the components comprising a system.
Graphic EQ: A form of EQ that has a number of faders for
controlling the gain of the audio signal. The faders are set
at frequency bands that are evenly-spaced according to
octaves.
GUI: Abbreviation for 'graphical user interface' .
GUI channel strip: Right section of a GUI screen that
represents the processing area of the input or output
channel strip selected to the control surface.
GUI menu: A menu selectable at either GUI screen by
clicking the home button (upper-left corner).
GUI screen: One of the M32's two screens, which comprise
the GUI.
H
HPF: Abbreviation for 'high pass filter' . A filter that removes
lower frequencies from a signal, leaving the higher
frequencies unaffected.
Hum: Undesirable low frequency tone present in a signal
due to grounding problems or proximity to a power source.
Hz: Symbol for 'Hertz' . A unit of frequency equal to one
cycle of a sound wave per second.
I

assignable effects controls.
I/O: Abbreviation for 'input/output' .
ID: Abbreviation for 'identification' .
Ident: Scale marking, or gradation, around a control knob
to help indicate the current setting and to assist in accurate
adjustment.

selection, and operator feedback.
LFE: Abbreviation for 'low frequency effects' . Typically, the
' . 1' in '5.1 surround' is an LFE channel.
LFO: 1. Abbreviation for Low-Frequency Oscillation, an
electronic signal which is usually below 20 Hz and creates
a rhythmic pulse or sweep. This pulse or sweep is often
used to modulate synthesizers, delay lines and other audio
equipment in order to create effects used in the production
of electronic music. 2. Abbreviation for Low-Frequency
Oscillator, the device itself which produces low-frequency
oscillation.
Linux: Also known as 'Linux kernel' . Operating system
kernel used by a family of Unix-like operating systems. See
kernel.
