Audio Review Most of the Final Exam will be focused on ‘Basic Media Production’ – audio and video. Test 4 will focus on lighting and sound. This is an audio review that helps you prepare for the audio part of Test 4 and the Final.

The ‘gauge’ on an audio board that shows the loudness levels coming through the board VU meter

The name for the type of analog audio connector ... RCA/phono, 1/4”/phone, mini-plug, XLR (see pictures in reading)

Later reflections of sound waves in an acoustical space—those that are the result of early reflections of sound waves becoming smaller and smaller and the time between them decreasing until they combine, are referred to as what? reverberation

The number of cycles that a sound vibration completes in one second frequency

A device that performs the function of converting energy from one form to another, as in from acoustical to electrical energy transducer

The common name for ‘volume controls’ on each channel of the audio board. Faders OR pots

A mode of console operation in which audio can be channeled and played through the monitor without that audio going out over the air audition

The name for the type of audio connector ... XLR -- jack left / plug right

The electrical imprint of a sound signal on a radio wave or carrier wave modulation

The functions of the audio console Amplifying, routing, mixing, balancing, switching

The term for the type of audio recording in which the fluctuations and changes of the electric wave pattern correspond to the fluctuations and changes in the original sound pressure analog

The number of cycles that a sound vibration completes in one second frequency

On an audio mixing board, the system that shuts off the monitor when the mic is on. muting

The objective study of the physical behavior of received sound. acoustics

The loudspeaker in an audio control room, used typically to listen to what is in program. monitor

Of the functions of the console, the one referring to determining the path of the signal. routing

The term for p-popping—in class we called them ----, when picked up by a mic. plosives

The prominent ‘s’ ‘sh’ and ‘ch’ sounds picked up by a microphone sibilance

The type of microphone that requires a power source to operate. Capacitor / condensor

The two means by which condensor mics are powered. Battery or phantom power

‘Mic +48v’ on the camera tells you what about that setting related to the mic input? That it must be a condensor mic if set this way, and it’s phantom power

Digital audio workstation DAW stands for ----- Digital audio workstation

The measure of the loudness of sound; the height of the sine wave amplitude

Amplitude is measured in ----, and when referring to loudness in an acoustical space would be abbreviated ---- Decibels ; dBspl Vs. dBv or dBm

Sound levels in an acoustical space are measured from the lowest end, or threshhold of ----- to the highest end, or threshhold of ----. Hearing ; pain

The range of loudness from lowest to highest levels, or the range of loudness that a microphone or other equipment can handle is referred to as ---- range. dynamic

The unique tonal quality of a sound is its ---, which the book says is when the overtones vibrate at different degrees of loudness according to the resonating qualities of each voice or musical instrument. timbre

Used when a mic needs to be suspended over a performer, such as while shooting sit-coms, dramas, and soap operas. boom

In digital encoding, the number of ones and zeroes used to represent a discrete moment of sound, such as an 8-bit word or 16-bit word, is referred to as the ----- level. quantizing

The ---- rate in digital encoding of audio is ‘how many times per second analog information is converted to the ones and zeroes of digital technology. sampling

Sound waves traveling in an environment, when striking a surface will be partially or mostly absorbed or partially of mostly ----- . reflected

Occasionally hitting the red When speaking into a mic or when playing music through a CD player or computer, the needle or light on a VU meter should be ----- Occasionally hitting the red

In digital video editing, the audio levels typically peak at ____ and must not go above _____ -6 to -3 dB O dB

Instead of distant miking for people speaking on camera, we must use a ----- miking technique or later re-record and insert the dialogue. close

(automated dialogue replacement In movie making, about half the dialogue cannot be close miked, requiring re-recording and inserting replacement audio, a process called: ADR / Looping (automated dialogue replacement
