Audio Production 2

limit listening through headphones to no more than on hour per day at levels below 60 percent of maximum volume

A loudspeaker that is powered internally

a signal processor that affects a signal’s loudness. The effects include compression, limiting, de-essing, expanding, noise gating, and pitch shifting

the length of time it takes a compressor to respond to the input signal

the difference between the upper and lower frequency limits of an audio component

in peak/dip equalizing, the frequency at which maximum boost or attenuation occurs

taking the best parts of each recorded track and combining them into a composite final version

• (1) Reducing a signal’s output level in relation to its input level to reduce dynamic range. (2)The drawing together of vibrating molecules, producing
• a high-pressure area.

the ratio of the input and output signals in a compressor

the level at which a compressor acts on an input signal and the compression ratio takes effect

a signal processor with an output level that increases at a slower rate as its input level increases

an electronic device that divides the audio spectrum into individual frequency ranges (low, high, and/or mid) before sending them to specialized loudspeakers such as the woofers and the tweeters

the time interval between a sound or signal and each of its repeats

the amount of time between delays

a multifunctional hard-disk production system, controlled from a central location that is integrated with and capable of being networked to other devices, such as audio, video, and MIDI sources, within or among facilities

a compact disc providing massive data storage of digital-quality audio, video, and text

a list of edits, computer-generated or handwritten, used to assemble a production

a signal processing device that can boost, attenuate, or shelve frequencies in a sound source or sound system

monitoring sound at the listening position from large, powerful frontal loudspeakers several feet away and usually built into the mixing room wall

a device that removes unwanted frequencies or noise from a signal

combining a direct signal and the same signal slightly delayed and continuously varying their time relationships, using a time delay

an equalizer with sliding controls that gives a graphic representation of the response curve chosen

used by musicians in live concerts to replace stage monitors

a compressor with an output level that does not exceed a preset ceiling regardless of the input level

having an output that varies in direct proportion to the input

a pronounced dulling of the auditory senses, inhibiting perceptual judgment

A data compression process during which no data is discarded

A data compression process during which data that is not critical is discarded during compression

monitoring with loudspeakers placed close to the operator, usually on or just behind the console’s meter bridge, to reduce interference from control room acoustics at the monitoring position

editing that does not alter the original sound or soundfile, regardless of what editing or signal processing is affected

assembly of disk-based material in or out of sequence, taken from any part of a recording and placed in any other part of the recording almost instantly (digital editing)

an equalizer in which the bandwidth of a selected frequency is continuously variable

a loudspeaker that is powered externally

a signal processor that affects a sound’s spectral range, such as equalizers, filters, and psychoacoustic processors

converting a waveform that is infinitely variable into a finite series of discrete levels

the length of time it takes a compressor to return to its normal level (unity gain) after the signal has been attenuated or withdrawn

multiple blended, random reflections of a sound wave after the sound source has ceased vibrating

(1) Examining an analog signal at regular intervals defined by the sampling frequency. (2) A process whereby a section of digital audio representing a sonic event, acoustic or electroacoustic, is stored on a disk or into electronic memory

the frequency (or rate) at which an analog signal is sampled

in hard-disk editing, moving the play cursor through the defined region at any speed to listen to a sound being readied for editing

computer hardware necessary to input, manipulate, and output audio

a sound stored in the memory of a hard-disk recorder/editor

in control room monitoring, the designated listening position, which is the optimal distance away from and between the loudspeakers

a signal processor that affects the time interval between a signal and its repitition

the informal name of a loudspeaker that produces high frequencies

graphic representation of a sound’s characteristic shape displayed, for example, on test equipment and hard-disk editing systems

informal name for a loudspeaker that produces the bass frequencies
