preserved as you switch, allowing you to compare your
best settings for each.
It is also a good idea to periodically use the Removed
button to hear what is being removed from the input signal.
If you hear components of the signal, then this may be an
indication that you are applying too much processing.
Finally,ifyouareworkingonastereorecording,itis
worthwhiletotryusingBackDropinbothStereoand
M/Smodes.Forcertainaudiosequencesadramatic
improvement in quality can be obtained by performing the
noise reduction processing in the M/S domain. You should
note that, in order to get the most from the M/S domain
processing,thecontrolsshouldbeunlinkedsothatdifferent
amounts of processing can be applied to the Mid and Side
signals. Specifically, it is often more perceptually beneficial
to apply more noise reduction to the Side signal than to the
Mid signal.
Common Questions
1)Isitbettertogetaslonganoiseprintaspossible?
The simple answer is yes, but the maximum length of the
capturebufferis1.5seconds.Sothereisnoadvantage
tohavinganoiseprintthatislongerthan1.5seconds.
BackDropdoesn’tneedmorethan1.5secondsinorderto
fully train itself on the noise in the signal.
2)Isitimportanttogetaverygoodloopofthenoise?
Again the answer is yes. If there is some signal in the
capturedbufferthenBackDropwillnottrainitselfproperly
about the nature of the noise that you are trying to remove.
That is, it will try to remove part of the signal as well.
3)Whatifitisnotpossibletogetanoiseprint?
This,ofcourse,willlimitBackDrop’sabilitytodecidewhat
is noise and what is signal. There are two approaches you
can use in this case.
a)Findanotherpieceofaudiowithsimilarnoiseanduseit
to capture the noise print information.
b)Findthequietestpartoftheaudiosignalanduseitto
capture the noise print information. Then use the MultiType
algorithm model to apply the noise reduction. Set the Buzz
AggressionandRoomAggressioncontrolsto0%.Usethe
Hiss Aggression to control the amount of noise reduction.
Thisisn’tperfect,butitshouldletyouachievesome
broadband noise reduction.
4)ShouldItrytoremoveallthenoise?
Oftenitisdesirabletoleavesomebackgroundnoisein
thesignalsothatitdoesn’tsoundunnaturallyclean.This
is primarily true for an overall mixed signal rather than for
individualtracksthatareyettobemixedtogether.
5)DoIalwayshavetousePlay,TrimStart/Endand
Calculatetogetagoodloop?
No.Thisisusuallyrequiredwhenworkingwithatape
transportorwhentakingaprintofaliveroomwhereitmay
be hard to anticipate the material.
Ifyouareworkingwithtracksonaharddiskrecording
system, it is often handy play a noise-only portion of the
trackinloop-modebeforepressingtheCapturebutton.
6)CanIpracticeusingBackdrop’scontrolsbycapturing
noiseandusingthecapturebufferinPlaymode?
Youcanusethistechniqueforquickcontrolchecksbutitis
not recommended for choosing final settings.
SinceBackdrop’sstrengthliesinallowingyoutoprecisely
control the amount of reduction to apply without altering
the signal, it is always better to fine-tune the controls with a
passagecontainingmusic.Focussingtoomuchonjustthe
noise can lead you to over-processing, giving unfavorable
results when you listen to the entire signal.
