- F -
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).
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 noise.
Feedback Control - The control on a delay line or delay effects device that controls the amount of feedback.
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).
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.
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.
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).
Frequency Range - The range of frequencies over which an electronic device is useful or over which a sound source will put out substantial energy.
Frequency Response - How sensitive an electronic device (mic, amplifier, speaker, etc.) is to various frequencies; often communicated with a graph.
