RECA 250 - Quiz 3 REVIEW QuestionsAnd Answers With Verified Solutions
100% Correct!!!
expanders - ANSWER✔✔ used in film mixing to help reduce background noise
- they are designed to pass strong signals through at normal level, but to reduce
the output level when the input signal level drops below a certain threshold
- ex. strong dialog would play normally, but during pauses in the dialog the
background noise, which is at a lower level, would be lowered still further
- some types of expanders are designed to focus on specific frequency ranges,
much like a graphic equalizer, rather than simply adjusting overall level
Compressors - ANSWER✔✔ used to reduce the level of loud peaks that rise above
a certain threshold
- by carefully increasing the level of the sound that goes into the compressor, the
net result is to increase the level of the softer portions of the sound relative to the
louder portions
- this has uses in making dialog or music sound louder or "fuller" overall
Suppose the engineers at SMPTE decided on a reference level of -14 dB instead of
-20 dB. If they played it back at a loudness of 85 dB SPL, how could that affect the
playback loudness of the loudest sounds in a digital release? - ANSWER✔✔ the
loudest parts of the movie would not sound as loud, because you have reduced
the headroom by 6 dB. the "normal" parts of the movie would still play at their
"normal" loudness, but the loudest parts would not be 20 dB louder than normal,
they'd only be 14 dB
Name the "5.1" channels in the 5.1 sound format - ANSWER✔✔ left, center, right;
left surround, right surround; and the "LFE" (subwoofer) channel
, In which channel does dialog almost always play? - ANSWER✔✔ center
which had more headroom, a film release print with a Dolby Digital soundtrack or
an analog Dolby Stereo Optical soundtrack - ANSWER✔✔ Dolby Digital has around
6 dB more headroom
if you always have a stereo's "loudness" switch turned on, regardless of how loud
you're playing music, what are you essentially accomplishing? - ANSWER✔✔
you're just turning up the bass and treble overall
if you are mixing a show to be viewed on television, should you listen with your
speaker system set to play reference level sound at 85 dB SPL? Or turn the
speakers up somewhat louder? or lower? - ANSWER✔✔ you would not use
standard theater level of 85 dB SPL for your television, so you would turn the
speakers somewhat lower based on comfortability
if you're mixing down music for a record album, and you're monitoring playback
much louder that the average consumer will play it, how might that affect your
EQ and other mixing choices, especially regarding bass? - ANSWER✔✔ You might
end up reducing the bass in the mix, since by playing it very loud you are
exaggerating the bass that you hear and you might EQ it to compensate for that.
What does a compressor do? Give an example where a compressor might be
useful - ANSWER✔✔ a compressor reduces the level of loud peaks that rise above
a certain threshold in a mix
