Homework 9 Responses - The Studio Environment Research Task -
Juuso
1. Complete thefollowing
descriptions: (a)The studio controlroom is... and (b)the studio
live /
performance roomis...
2. In your ownwords, pleasestate what aroom with a
flat frequencyresponse is.
3. Why is itdesirable for
control roomsto have a flat
frequencyresponse?
4. What areroom
"reflections"?
5. Why is it often(but not always)desirable for liverooms to
have
reducedreflections?
6. Describe 2ways in which
room reflectionsare reduced.
7. What is a basstrap?
8. What is"near-field"monitoring?
9. Describethe
differencebetweenpoweredmonitors,and those
that requirea power
amplifier.
10. What is abalanced line
input?
11. Whyare activeDI boxesgenerally
betterthan
passiveones?
12. What areheadphonedistributionamplifiers?
13. Describethree other
considerationswhich should beimplemented in a
studioenvironment toavoid unwanted
audiointerference.
14. What areclosed backedheadphones
and why, in theevent of
needing to
monitor arecording onheadphones
rather than onnear-field
monitors, doesa studio
engineer needto use this typeof headphone?
A) The studio controlroom is where themain hardware forrecording
is stored;a mixer, monitorsand cabling from thelive room.
Isanyother equipmentoften present?B)The live roomshould be as
deadas possible (deadmost of the time butnot always), inacoustic
terms.Ideally a live roomshould have; a flatfrequency response,
avoiding anemphasis onstanding waves andbass boom. GoodJuuso
A flat frequencyresponse iswhen in
aspecificrecordingenvironment,there is noboost or cut inany of
thefrequenciespickedup.which can
be caused bystanding wavesand otherundesirablereflections
Becausegenerally a flatfrequencyresponsetranslates well toother
systemsand formats(cd,vinyl, mp3)Youre kindaright, but youranswer
lacks the
detail required(although you arecertainly alongthe right
lines)
So that you canhear the exactand naturalfrequencycontent of
youraudio, knowingthat it is not beingover or underexaggerated
bythe frequencycontent of yourcontrol room.Exaggeratedroom
freq.responses tendto result in the
engineer /producer over orunder using EQto compensate.
Room reflectionsare whenwaveforms reflectoff specificsurfaces in
therecording space,i.e windows orwalls. These cancreate a
messyrecording and aregenerallyundesirable.
Undesirable,unless of courseyou want a
room sound its thesereflections thatgive us ambienceafter all
Juuso!
As the ambianceproduced by roomreflections can berecreated
usingprocessing,therefore giving theengineer muchgreater control
overthereverb/ambiance.
This is not alwaysdesirable becausesometimes you
want the naturalambience of aroom or space tobe captured in
therecording process.
Acoustictiling/carpets andnon-parallelceilings and walls.
What would you doif you you did haveparallel wallsJuuso?
Think
about the positionof the soundsource and
thewordperpendicular
An objectdesigned to beplaced within alive room, toresonate with
thelow frequencies.Nope! You dontwant anything toresonate with
thefreq. of the room
this wouldenhance thereflections, notabsorb them!
A bass trap is apiece of acoustictreatment (oftenfoam) that sits
inbetween the joinbetween twowalls (often butnot always a
rightangle 90 degreejoin). This isdesigned to helpwith the build
upof standing wavesand thereforeexaggerated bassfrequencies
that
are often presentin the corners ofrooms wherewalls, floors,
andceilings join.
Studio
monitorsdesigned tobe listenedtoo, close
range
A poweredmonitor hasa built inamplifierwhereas,
amonitorwhichrequires apower ampuses a
power ampto boost theline level tospeakerlevel.
A balanced
cable is one inwhich the twowires haveoppositepolarity
sotherefore thecancel outany unwantedinterference.
Almost rightJuusoexcept thereare 3 wiresand 3 pinsapositive,
anegative, anda ground.
You shouldalso mention
that unwantedinterference iscancelled outvia
phasecancellation.
Active DIboxes arepowered,quieter,have more
variety andcan handlelongercable runs.
Headphonedistributionamplifiers areintended to feedmultiple sets
of
headphonessimultaneously.
Feed them withwhat?
avoid usingfluorescent lightsor computers inthe live room,
asthey producepowerful magneticfields. Cable runsshould be kept
as
short as possible.Also, separationfrom externalacoustic
noises.
Closed backheadphones areheadphoneswhich cover theears. This is
so
that the engineercan provide agood monitoringof the roomwhilst
not spillinginto the actualrecording.
Also importantlyclosed-backedheadphonesreduce soundleaking into
theheadphonesfrom othersourcesmeaning that theengineer canhear the
truesound of therecording free
from colourationof roomacoustics andback groundnoise
