Fade - 1) A gradual reduction of the level of the audio
signal. 2) A gradual change of level from one pre-set level to another.
Fader - A control to control the gain of a channel on the
console, thereby determining the level of the signal in that channel.
Far Field - The area from 3 feet away from the sound
source up to the critical distance.
Fat - Having more than a normal amount of signal strength at
low frequencies or having more sound than normal (by use of compression or delay).
Feed - To send an audio or control signal to.
Feedback - 1) The delayed signal sent back to the input
of a delay line, used in repeat-echo effects. 2) The pickup of the signal out of a channel
by its input or the howling sound that this produces. 3) In an amplifier, the phase
reversed output signal sent back to its input, reducing gain but also distortion and
Feedback Control - The control on a delay line or
delay effects device that controls the amount of feedback.
Fidelity - The recording or reproduction quality.
Field - 1) In video, one half of a frame. 2) In
computer-controlled devices a window display with functions and choices that the operator
Figure Eight Pattern - Another name for
Bi-directional Pattern (microphone pickup pattern picking up best from the front and back
of the diaphragm and not picking up from the side of the diaphragm).
File - A collection of digital data stored in a computer's
memory bank or on a floppy disc.
Filter - 1) A device that removes signals with frequencies
above or below a certain point called the cut-off frequency. 2) An equalizer section, used
in this sense because filters are used with other components to give an equalizer its
frequency response characteristics. 3) The action of removing signals of some frequencies
and leaving the rest. 4) A mechanical device to smooth out speed variations in tape
machines called a Scrape Flutter Filter- more usually called a Scrape Flutter Idler
Final Mix - The two track stereo master tape which was
mixed from the multitrack master.
First Generation - A descriptive term meaning
original (as opposed to a copy).
Flange - An effect caused by an approximately even mix of a
modulated (varying) short delay with the direct signal.
Flat - 1) Lower in musical pitch. 2) A slang term used to
describe the sensitivity to frequency of a microphone, amplifier, etc., as being even at
all frequencies, usually within 2 dB.
Fletcher Munson Effect - A hearing
limitation shown by Fletcher Munson Equal Loudness Contours (as music is lowered in
volume, it is much more difficult to hear bass frequencies and somewhat harder to hear
very high frequencies).
Floor - 1) An alternate tam meaning Range (a limit on the
amount the signal is reduced when the input signal is low by an expander or gate). 2) A
shortening of the term Noise Floor (the level of the noise).
Floor Toms - The large toms to the right of the
Floppy Disk (Floppy Disc) - A round flat object
(usually housed in a protective sleeve) coated with material that can be magnetized in a
similar manner to tape.
Flutter - 1) High-frequency variations in pitch of a
recorded waveform due to fast speed variations in a recorder or playback machine. 2)
Originally, and more formally, any variations (fast or slow) in pitch of a recorded tone
due to speed fluctuations in a recorder or playback unit.
Fly In - 1) To add sounds into a mix or recording that have
no synchronization. 2) An application of this where a performance from one part of a tune
is recorded and then recorded back into the recording at a different time in the
Foldback - A European term for the signal sent to the
stage monitors in a live performance.
Foot (Foot Drum) - Another name for
Bass Drum (the largest drum in the Drum Kit which puts out bass frequencies and is played
with a foot pedal).
Foot Pedal - 1) An effects device where the amount of
the effect can be controlled by a musician with his foot. 2) The beater mechanism of a
foot drum that is activated by the drummer's foot to play the drum. 3) Any device, like a
volume control, that can be operated by the foot.
Foot Switch - A switch placed on the floor and pressed
by a musician to do various functions.
Formant - An element in the sound of a voice or instrument
that does not change frequency as different pitches are sounded.
Format - 1) The number of tracks, their width, spacing and
order for tape recording. 2) To prepare a digital storage medium so that it will accept
and store digital information bits.
Frame - 1) A division of one second in synchronization and
recording coming from definition two. 2) The amount of time that one still picture is
shown in film or video.
Frequency - The number of cycles of a waveform occurring
in a second.
Frequency Range - The range of frequencies over
which an electronic device is useful or over which a sound source will put out substantial
Frequency Response - How sensitive an
electronic device (mic, amplifier, speaker, etc.) is to various frequencies; often
communicated with a graph.
Frequency Shift Key / FSK -
The full name for FSK (A simple clock signal that can be used to run a sequencer in time
with an audio tape).
Full - A quality of the sound of having all frequencies
present, especially the low frequencies.
Full Step - A change in pitch that occurs when moving up
or down two piano keys
Fundamental - The tuned
frequency and (almost always) the lowest frequency that is present in the sounding of a
pitch by a musical instrument.
