how energy that produces sound travels
highest point of a wave. With a sound wave, the crest represents the maximum pressure of air molecules
lowest point of a wave. With a sound wave, the trough represents maxiumum release of air molecules.
speed of a wave in relation to time
the measurement of one cycle of a wave
the number of cycles that the sound wave travels in 1 second (cps) (cycles per second)
wavelength = velocity/frequency
how high or low a sound is
height of a save. with sound waves, it determines loudness (measured in decibels)
weakening of an energy wave as it travels
the conversion of one form of energy into another
part of the electromagnetic spectrum that is used for wireless broadcasting communication.
amount of resistance to a signal
type of microphone that uses a coil and magnet to produce an electric audio signal
has a strip of metal instead of a coil
condenser mikes/capacitor mikes
type of microphone that uses two charged metal plates (one moving, one fixed) to create an audio signal
externally-provided power circuit used for pre-amplification in condenser microphones
capacitance mike that has permanently charged plates that require only a very small battery for preamplification
sensitivity across a range of frequencies
the area around the microphone in which sound will be clearly reproduced
three classifications of microphones
omnidirectional, bidirectional, unidirectional
classification of microphone pickup pattern that includes the left and right sides of a microphone
ability of human ears to perceive differences in location, direction, and presence of sound
amount of digital information taken within each individual sample
transmission of radio waves from one point of origination to an unlimited number of receivers over a relativel large area.
another name for a unidirectional mic pickup pattern that describes the pickup's heart-shaped pattern of sensitivity
end result of the analog recording process based on the direct relationship between the original waves and the recorded signal.
unit of measurement for amplitudes of a sound wave
a form of solid-state drives such as an SD card or a Compact Flash Card
result of an analog-to-analog signal transfer (or "dub"), which creates an amplification of the noise within the original recorded sound or image and subsequent reduction in quality.
mic designed for use in proximity to subject. Can be held or placed on a stand
group of similar frequencies that creates a specifc sound
basic unit of measurement for the frequency of sound
small mic designed to attach to a subject
mechanism that measures the amount of voltage in an audio signal. The info is displayed by a series of light-emitting diodes on a metered scale.
process of listening to an audio signal during recording to ensure proper levels and sound quality.
classification of mic pick-up pattern that includes the entire surrounding area, eliminating only the area directly behind the mic
proper location of the subject within the pick-up pattern of a mic for optimum audio recording quality
point at which the peak of an audio signal exceeds the max safe recording range and risks the possibility of distortion.
highest point of voltage within an audio signal
a term derived from the Apple Ipod referring to an audio production that can be downloaded or streamed to a personal computer
conversion of a sample signal into mathematical units
multiple reflections of a sound off all the surfaces surrounding the intitial source.
ride the gain
to adjust the level while recording or taping
the sound of a space or its ambient sound
measurements of an analog signal that allow the creation of a digital stream of binary data (ones and zeroes)
number of digital samples taken per second
mic with a narrow pickup pattern designed for recording audio at a distance from the source, usually as a method of removing the mic from the frame of the image
relative proportions of desired info and interference
the shape of the soundwave
concept of matching of sound presence and shot size and establishing a sense of where the sound source is coming from
subjective sense of sound proximity. a sound that seems close to the listener has a lot
method of recording, mixing, and playing back audio on two separate channels or tracks.
media presentation technique that allows for simultaneous viewing or listening while downloading rich media from the internet onto a computer
uses four or more speakers around the listening area.
distinctive tonal quality of a sound
mic pickup pattern that includes a limited area in front of, to the sides of, and behind the mic
mechanism that measures the amnt of voltage in an audio signal. a needle indicates volume units or percentage of signal on a linear scale, or LEDs displa the strength of the signal.
natural sound of a location
automatic dialogue replacement (ADR)
actors watch them speak on screen and then respeak their lines. Cleanly recorded dialogue tracks are then mixed with ambience tracks and sound effects to recreate the og sound- BUT BETTER.
lines spoken by subjects or actors that are part of the story
existing within the reality of a story
creation of sound effects as part of a sound deisgn
lines spoken that describe or reflect on the action but are not a part of it
sound or music that exists outside the reality of the story in a film or video production, such as background music or a voice-over narration
sound that is recorded separately from the film or video image
composition of music to complement visual elements and heighten mood in a media production
device used to synchronize the simultaneous shooting of film and recording of sound. can be manual or digital
technical and aesthetic plan to combine sound elements to work together as a whole or in combination with image
sounds created to emphasize or add to the action
all sound sources combined together
sounds that matches the action-recorded as the film or video image is acquired
narration for a film or video that can be written and spoken in either the first or third person.
