Audio Production 2

  1. 60 percent/60-minute rule
    limit listening through headphones to no more than on hour per day at levels below 60 percent of maximum volume
  2. Active loudspeaker
    A loudspeaker that is powered internally
  3. Amplitude or dynamic
    a signal processor that affects a signal’s loudness. The effects include compression, limiting, de-essing, expanding, noise gating, and pitch shifting
  4. Attack time
    the length of time it takes a compressor to respond to the input signal
  5. Bandwidth
    the difference between the upper and lower frequency limits of an audio component
  6. Center frequency
    in peak/dip equalizing, the frequency at which maximum boost or attenuation occurs
  7. Comping
    taking the best parts of each recorded track and combining them into a composite final version
  8. Compression
    • (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.
  9. Compression ratio
    the ratio of the input and output signals in a compressor
  10. Compression threshold
    the level at which a compressor acts on an input signal and the compression ratio takes effect
  11. Compressor
    a signal processor with an output level that increases at a slower rate as its input level increases
  12. Crossover network
    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
  13. Delay
    the time interval between a sound or signal and each of its repeats
  14. Delay time
    the amount of time between delays
  15. Digital audio workstation
    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
  16. Digital versatile disc
    a compact disc providing massive data storage of digital-quality audio, video, and text
  17. Edit decision list
    a list of edits, computer-generated or handwritten, used to assemble a production
  18. Equalizer
    a signal processing device that can boost, attenuate, or shelve frequencies in a sound source or sound system
  19. Far field monitor
    monitoring sound at the listening position from large, powerful frontal loudspeakers several feet away and usually built into the mixing room wall
  20. Filter
    a device that removes unwanted frequencies or noise from a signal
  21. Flanging
    combining a direct signal and the same signal slightly delayed and continuously varying their time relationships, using a time delay
  22. Graphic equalizer
    an equalizer with sliding controls that gives a graphic representation of the response curve chosen
  23. In-ear monitor
    used by musicians in live concerts to replace stage monitors
  24. Limiter
    a compressor with an output level that does not exceed a preset ceiling regardless of the input level
  25. Linearity
    having an output that varies in direct proportion to the input
  26. Listening fatigue
    a pronounced dulling of the auditory senses, inhibiting perceptual judgment
  27. Lossless
    A data compression process during which no data is discarded
  28. Lossy
    A data compression process during which data that is not critical is discarded during compression
  29. Near-field monitor
    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
  30. Non-destructive editing
    editing that does not alter the original sound or soundfile, regardless of what editing or signal processing is affected
  31. Non-linear editing
    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)
  32. Parametric equalizer
    an equalizer in which the bandwidth of a selected frequency is continuously variable
  33. Passive loudspeaker
    a loudspeaker that is powered externally
  34. Plug-in spectrum processors
    a signal processor that affects a sound’s spectral range, such as equalizers, filters, and psychoacoustic processors
  35. Quantization
    converting a waveform that is infinitely variable into a finite series of discrete levels
  36. Release time
    the length of time it takes a compressor to return to its normal level (unity gain) after the signal has been attenuated or withdrawn
  37. Reverberation
    multiple blended, random reflections of a sound wave after the sound source has ceased vibrating
  38. Sampling
    (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
  39. Sampling frequency
    the frequency (or rate) at which an analog signal is sampled
  40. Scrubbing
    in hard-disk editing, moving the play cursor through the defined region at any speed to listen to a sound being readied for editing
  41. Sound card
    computer hardware necessary to input, manipulate, and output audio
  42. Soundfile
    a sound stored in the memory of a hard-disk recorder/editor
  43. Sweet spot
    in control room monitoring, the designated listening position, which is the optimal distance away from and between the loudspeakers
  44. Time processor
    a signal processor that affects the time interval between a signal and its repitition
  45. Tweeter
    the informal name of a loudspeaker that produces high frequencies
  46. Waveform
    graphic representation of a sound’s characteristic shape displayed, for example, on test equipment and hard-disk editing systems
  47. Woofer
    informal name for a loudspeaker that produces the bass frequencies
