    Image Upload 1
  3. Image Upload 2
    Downward Compression
  4. Image Upload 3
    Upward Compression
  5. Which compression (upward or downward) does not exist in analog?
  6. What do spectral processors manipulate and what are the basic types?
    Spectral Processors - manipulate the sound spectrum - frequency based.

    - Filters –  Equalizers –  Aural Exciters
  7. What do dynamic processors manipulate and what are the basic types?
    Dynamic Processors - manipulate the dynamic range - amplitude based.

    –  Compressors –  Limiters –  Expanders –  Gates –  DeEsssers –  Duckers
  8. What do time based processors manipulate?
    Time Based Processors - manipulate the time domain aspects of the sound.
  9. Cutoff Frequency:
    the frequency where the output is 3.01 dB below zero.
  10. Slope is measured by:
    dB per octave
  11. Image Upload 4
    Band Reject Filter
  12. Image Upload 5
    Notch Filter
  13. What are limiters?
    Compressors with infinite or high ratios of at least 10:1
  14. What is an expander? What is the most common expander?
    • Increases dynamic range. 
    • Downward expander
  15. What is a gate?
    An expander with an infinite ratio. Signals below the threshold are effectively eliminated.
  16. What is a side chain?
    allows a signal other than the processed signal to control the detector circuit.
  17. What is a sidechain where the music gets pushed down when the voice comes in?
  18. Whtat is a DeEsser?
    Compresses 4-6kHz range. Also good to get rid of fret noise.
  19. Time Between the direct sound and the first reflection.
  20. First initial echoes perceived separately.
    Early Reflections
  21. Which type of reverb has more low end?
    Acoustical reverb
  22. Which type of reverb has no pre-delay?
    Mechanical plate
  23. What are some advantages of digital reverb?
    What are some disadvantages?
    • -Very flexible
    • -Compact
    • -Automation possible

    • -Limited lifespan
    • -Learning curve
    • -Not "real thing," but sometimes better, so...
  24. What is rever?
    Direct sound + early reflections
  25. a single duplication of a signal that is reproduced later in time.
  26. a distinct repetition(s) of a sound event (>125 ms).
  27. a single short delay (80-125ms)
  28. a short delay mixed with the original signal to “fatten” the sound (30-80ms).
  29. a pattern of change applied to one or more delay parameters.
  30. Two copies of a track played simultaneously.
  31. Process by which we determine the directional orientation of a sound source.
  32. Which Interaul Difference effects low frequencies more?

    High frequencies?

  33. What are the two binaural cues humans use to localize noises?
    Interaural Time Difference

    Interaural Amplitude Difference
  34. What are the 3 main stereo micing techniques?
    Spaced Pair

    Coincident pair: stereo micing achieved through amplitude differences

    Near Coincident pair
  35. Which stereo micing technique can't use omni mics?
    Coincident pair
  36. Which stereo micing technique has no phase?
    Coincident pair
  37. What the three main coincident pair micing techniques?
    XY: has to be cardioid mics. Can be center heavy.

    Blumlein: Bi-directional mics at 90*

  38. What is the most common near-coincident pair micing techniques?
    ORTF: cardioid mics.
  39. What are the 3 main audio connectors?
    • Two pin
    • Three pin
    • Multi pin
  40. What are the differences between balanced and unbalanced connectors?
    Unbalanced have 2 connectors and Balanced have 3 connectors

    Balanced are "hot" and grounded. Unbalanced are "cold" (out of polarity) and grounded.

    Unbalanced are subject to interference.

    Unbalanced are used for consumer, semi-pro, and short cable runs. Balanced are used for pro applications.
  41. Which pin on an 3 pin connector is hot?
    Pin 2
  42. What is Common Mode Rejection?
    The rejection by the device of unwanted input signals common to both input leads, relative to the wanted difference signal.
  43. Which Listening mode is destructive?
    Solo In Place
  44. Which listening mode is mono?
    Pre-Fader Listen (PFL)
  45. Which listening mode is good for tracking?
    After-Fader Listen (AFL)
  46. Which listening mode uses the mix buss?
    Which uses its own solo bus?
    Solo In Place

    Pre-Fader Listen (PFL)
  47. What are the two types of masking and what are they based on?
    Spectral: Frequency based

    Temporal: Timing based
