Comprehension exercise 7 and 8
Show Answers:

  1. What is the difference between Bypassing a plug-in and making it Inactive?
    Making a plug-in inactive stops using processing power. Bypassing just ignores the plug-in while still using power from it.
  2. What is the difference between RTAS, TDM, and both version of the AAX plug-in formats?
    • RTAS (Real Time Audio Suite)- Normal version of plug-in. Old school (dead). 
    • TDM- HD version of plug-in. Old school (dead).
    • AAX Native- New RTAS. Processes inside computer.
    • AAX DSP- New TDM. Processes outside computer in chip.
  3. What is the difference between a mono plug-in and a mono/stereo plug-in?
    • Mono plug-in: One input and output.
    • Stereo plug-in: One input and two outputs.
  4. What is the difference between a multichannel and a multi-mono plug-in?
    • Multi-channel: Two ins and outs. One engine.
    • Multi-mono: Two pedals; one for left and one for right.
  5. What should the Mix (Wet/Dry ratio) typically be for a plug-in inserted on an Aux Return track?
    100% wet, so there's no duplicated dry signals coming from the % that's dry and the track's dry signal.
  6. What are the essential differences between serial and parallel processing?
    • Serial: plug-ins on top of each other on a track.
    • Parallel: Plug-ins in an AUX track.
  7. What is ADC and what is it’s purpose when mixing?
    Automatic Delay Compensation: Compensates for the delay from processing.
  8. Where in Pro Tools does it indicate the delay time incurred by all of the plug-ins on a track?
    The bottom of the mix window. (dly)
  9. How does a compressor affect the dynamic range of a signal?
    Lowers the dynamic range of a signal. Lowers a signal level when it exceeds threshold. Automated volume controller.
  10. From a technical perspective, what does an equalizer do exactly and what are the three primary user-adjustable controls on a standard parametric EQ?
    • Adds gain or subtracts it from a signal.
    • Frequency center, cue, gain.
  11. What is the difference between a graphic and a standard parametric EQ?
    • Graphic: Controls boosts or cuts of frequencies.
    • Parametric: Controls 3 aspects of each frequency- level (boost/cut), the center frequency, and the bandwidth.
  12. Aside from input or output controls, what are the two user-adjustable controls on the high and low-pass filters in the DigiRack EQ3 plug-ins, and what do these controls affect?
    • Slope: how quickly a frequency is cut. 
    • cutoff frequency: What frequency is cutoff.
  13. What are two differences between a filter (e.g., low-pass, high-pass) and a shelf?
    Filters: Cut out a frequency band entirely. shelves: Only alter a band a certain amount. Shelves have a consistent alteration while filters cut out more and more in the direction being cut.
  14. Describe the concept of “corrective EQ” and “complementary EQ”
    • Corrective: Fixes unwanted problems in a signal.
    • Complimentary: Boosts a certain frequency on one instrument and dips that same frequency on another instrument so it all sounds equal.
  15. How is a compressor both similar to and different from a simple fader?
    Compressors act as "automatic faders" bringing down the level when it exceeds the threshold.
  16. What purpose does the threshold setting on a compressor serve?
    The threshold is the point of level at which the compressor will activate to bring it back down below threshold.
  17. Everything else being equal, will a compressor with a threshold of –16 dBFS compress a signal more or less than a compressor with a threshold of –20 dBFS? Why?
    • -16 will compress less than -20. 
    • -20 has a smaller threshold that will hit sooner.
  18. What purpose does the make-up gain on a compressor serve
    It brings the overall average signal level back up to an appropriately equal level.
  19. What does the attack time on a compressor measure?
    It adjusts how soon the compressor activates when a signal level exceeds threshold.
  20. Using a preset on a compressor plug-in, what two parameters are almost guaranteed to be incorrect for the signal you are trying to compress?
    Threshold and makeup gain.
