Audio 3 Flashcards
An audio signal processor that is used to remove excess sibilance from certain vocal tracks. Generally it is a specialized form of compressor with an equalizer in its level detection circuit that causes it to be more sensitive to high frequencies, thus restricting high level high frequency sounds.
De-Essex
A device which delays an entire audio program signal by a certain amount of time. Usually from 0 to 1250 milliseconds
Delay Line
Any insulating material, although the term usually refers to the material between the plates of a capacitor
Dielectric
A numerical representation of the actual analog frequency and level of an audio signal. Refers to a control circuit which changes the level or assignment of a signal in discrete mathematical steps rather than continuously variable.
Digital
The pattern of sound distribution from a speaker
Dispersion
An unwanted change that occurs to an audio signal, causing frequency to appear at the output that were not present at the input of the audio device
Distortion
One or more discretely discernible delayed sound images
Echo
A mixing console output that sends a signal form the a reverberation chamber or device.
Echo send
A mixing console input that receives the signal from the output of a reverberation chamber or device
Echo return
A mixing console output that sends a signal to the input of an effects device
Effects send
A mixing console input that receives the signal from the output of an effects device.
Effects return
The moments to moment changes in overall signal level of a program. A composite wave form which includes all frequencies and signal components
Envelope
An electronic device that will make loud parts of the program louder or quiet to increase (expand) the dynamic range. Used to reduce analog tape noise or to reduce leakage from other instruments (during recording or playback)
Expander
A potentiometer that controls the signal level of a console input position or output channel. May be linear or rotary
Fader
A special effects device used to create an effect originally created by carefully manipulating two tape recorders which recorded and played the same original. Like phasing, but tends to impart a musical quality even to non-musical sounds.
Flanger
