Hard Clipping vs. Soft Clipping & Oversampling Explained
Summary
TLDRDieses Video erklärt die Grundlagen von Clipping in der Audiomastering-Welt, unterscheidet zwischen Hard- und Soft-Clipping und erläutert den Prozess der Übersampling. Es zeigt, wie Clipping-Plugins wie Standard Clip, Gold Clip und Orange Clip unterschiedliche Algorithmen zur Klanggestaltung anwenden. Übersampling wird als Mittel vorgestellt, um beim Clipping Klangartefacts zu vermeiden und die Obertöne zu kultivieren, was für eine bessere Klangqualität im Endprodukt essentiell ist. Der Fokus liegt auf einer verständlichen Darstellung, um Musikern und Produzenten die Kontrolle über ihre Klangprofile zu geben.
Takeaways
- 🔊 Clippers sind eine beliebte Art von Plugin, die zur Kontrolle der Lautstärke und zur Verarbeitung von Audiosignalen verwendet wird.
- 📈 Clippers werden oft im Masteringprozess verwendet, um die Spitzen der Audiowellen zu beschneiden oder abzurunden, bevor das Limiter-Plugin angewendet wird.
- ✂️ Hard Clipping ist eine Art der Signalbeschneidung, bei der die Spitzen der Transiente direkt abgeschnitten werden, ähnlich wie ein Baum mit einer Kettensäge abgeschnitten wird.
- 🌱 Soft Clipping hingegen ist eine sanftere Art der Signalbeschneidung, die die Spitzen sanft abrundet, ähnlich wie ein Baum mit einer Sense abgerundet wird.
- 🎶 Soft Clipping kann oft einen musikalischeren Klang erzeugen und fügt dem Signal Harmonik und Distortion hinzu, während Hard Clipping die Dynamik und die Transiente stärker beeinträchtigt.
- 📊 Die Wahl zwischen Hard und Soft Clipping hängt von der gewünschten Klangqualität und dem erforderlichen Grad an Kontrolle über die Spitzen ab.
- 🔧 Übersampling ist ein Prozess, bei dem die Audiosignale mit einer höheren Samplingrate verarbeitet werden, um mehr Details und weniger Artefakte zu erhalten, insbesondere bei der Verwendung von Clippers.
- 🌐 Übersampling kann die Qualität der hohen Frequenzen verbessern und helfen, Aliasing- und Distortion-Artefakte zu vermeiden, die durch das Clipping entstehen können.
- 🔊 Die Verwendung von Clippers anstelle von Limitern ermöglicht eine bessere Kontrolle über die Spitzen, da Limiter die Spitzen lediglich reduzieren, ohne sie abzurunden oder abzuschneiden.
- 💾 Übersampling ist besonders wichtig, wenn man Audiodateien bouncen möchte, um sicherzustellen, dass die Verarbeitung der Spitzen und die Klangqualität beibehalten werden.
- 🌟 Jede Art von Clipper hat seinen eigenen Charakter und kann unterschiedliche Harmonik und Distortion hinzufügen, was die Klangqualität beeinflusst.
Q & A
Was ist das Hauptthema des Skripts?
-Das Hauptthema des Skripts ist die Erklärung von Hard Clipping, Soft Clipping, Clippers im Allgemeinen und Übersampling in der Audio-Mastering-Kette.
Wo wird ein Clipper normalerweise in der Mastering-Kette eingesetzt?
-Ein Clipper wird normalerweise direkt vor dem letzten Limiter in der Mastering-Kette eingesetzt, manchmal kann er aber auch das letzte Plug-in in der Kette sein.
Was ist der Unterschied zwischen Hard Clipping und Soft Clipping?
-Hard Clipping schneidet die Spitzen der Transienten direkt ab, ähnlich wie mit einer Kettensäge. Soft Clipping rundet die Spitzen sanft ab, wie mit Scheren, und fügt oft harmonische Verzerrung hinzu.
Was sind Clippers und warum werden sie verwendet?
-Clippers sind Audio-Effekte, die dazu dienen, die Spitzen der Audio-Signale abzuschneiden oder zu runden, um mehr Dynamik und Kontrolle über die Peaks zu erhalten und die Audiodatei lauter zu machen.
Was ist Übersampling und wie hilft es bei der Verwendung von Clippers?
-Übersampling ist ein Prozess, bei dem die Abtastrate erhöht wird, um mehr Informationen über das Audio-Signal zu sammeln. Dies hilft, Verzerrungen und Artefakte zu reduzieren, die durch das Abschneiden der Spitzen mit Clippers entstehen können.
Was ist der Unterschied zwischen einem Limiter und einem Clipper?
-Ein Limiter reduziert die Lautstärke der Spitzen, wenn sie einen bestimmten Schwellenwert überschreiten, während ein Clipper die Spitzen direkt abschneidet oder runtet, um Verzerrungen hinzuzufügen oder zu kontrollieren.
Was sind die verschiedenen Modi, die im Standard Clipper zur Verfügung stehen?
-Im Standard Clipper gibt es Modi wie Soft Clip Pro, Classic und Hard Clip, die jeweils unterschiedliche Arten von Verzerrung und Klangcharakteristik bieten.
Was ist die Bedeutung von 'oversampling' im Kontext des Skripts?
-Übersampling ist ein Feature in Clippers, das die Abtastrate erhöht, um eine detailreichere Darstellung des Signals zu ermöglichen und so die Qualität des Signals zu verbessern, insbesondere in der Obertönbereich.
Welche Art von Verzerrung wird durch Hard Clipping erzeugt?
-Hard Clipping erzeugt eine Art von Verzerrung, bei der die Spitzen des Signals unmittelbar abgeschnitten werden, was zu einer harten, unmusikalischen Klangcharakteristik führen kann.
Was sind die Vor- und Nachteile von Hard Clipping im Vergleich zu Soft Clipping?
-Hard Clipping bietet mehr Dynamik-Reserve, da die Spitzen abgeschnitten werden, kann aber die Transienten weniger prägnant wirken lassen. Soft Clipping ist oft musikalischer und fügt harmonische Verzerrung hinzu, kann aber nicht so effektiv die Lautstärke steigern.
Welche Faktoren sind zu berücksichtigen, wenn man Clippers in der Mastering-Kette einsetzt?
-Man sollte berücksichtigen, wo im Mastering-Kette der Clipper platziert wird, welche Art von Clipper verwendet wird, ob Übersampling angewendet wird und wie die verschiedenen Modi des Clippers die Klangcharakteristik beeinflussen.

Transcripts
recently I've been getting a lot of
questions about hard clipping soft
clipping and Clippers in general Clipper
plugins right seems to be like all the
rage everything is Clippers new Clipper
plugin clip clip clip gold clip orange
clip standard clip clippity clip we're
going to clip it up and then I took my
hair and I just clipped it all off in
this video I actually want to explain
what clipping is hard clipping soft
clipping and oversampling and how that
all works together hopefully I'm going
to demystify some things for you guys
that are watching this and if I do
please drop some love on the video share
the show all right let's dive in before
we get started I want to explain a
little bit about where Clippers usually
work the best in a mastering chain now
of course you could use a Clipper on a
subgroup like a drum mix bus or a vocal
mix bus or really anything and hard
clipping versus soft clipping we're
going to get into all that especially
with oversampling because I feel like a
lot of people don't really understand
what those things are and those features
and they don't know why they're turning
them on why they're turning them to 10x
or 4X or 20x on oversampling and their
computer's crashing and they're like yo
what am I doing here I'm going to talk
about all that stuff in this video so
let's go first things first where do we
put the Clipper in the actual chain on
the mastering I tend to put a Clipper
right before my last limiting on the
track now I kind of change it back and
forth sometimes the Clipper comes at the
very last plug-in in the chain but often
times it's right before the last limiter
phase all right so let's check out these
Clippers first of all the master bus
let's break that down uad manly variable
Mew doing some very light compression
and adding some harmonics from driving
the input which is tubes we know it's a
plug-in but it's modeling the tube
circuitry of the manly variable mu then
I have the Goos doing some cleanup and
kind of taking care of uh eqing for me a
little bit separating things a little
bit more and then we have the soo 2
which is doing some kind of soothing on
the top end and I have four times Ultra
on the over samp
we'll explain that again in this video
and what oversampling is exactly and
then I have the ozone 9 plugin from
isotope which is doing some Dynamic
eqing and the maximizer which is doing
some limiting and then I'm going to pop
on my Clipper now I have three Clippers
here I have the standard clip I have the
gold clip and I have the orange clip and
we're going to talk about how all these
different Clippers work differently but
they're all doing the same thing they're
all doing either hard clipping or soft
clipping so the best way to think about
hard clipping is to think about it if
you're trimming bush or your Hedges
right you have a tree and you take a
chainsaw and you just chop the tree just
the tip of the tree right off that's
hard clipping straight up it's just a
hard cut it's cutting off the peaks of
the transients of the information that
you're feeding it okay soft clipping is
like taking that tree coming up to it
with some shears and by hand softly
rounding off the top of the tree and
taking off just little Peaks but
rounding it okay so soft clipping is the
knee it's like a a slower knee right so
shaping it shaping the waveform often
times it's more musical add some
harmonics and Distortion coloration
depending on the plugin they all have
different algorithms and different
harmonics that they're adding odd even
even only odd only Etc and with hard
clipping you're just clipping the top
okay you're just shaving it right off
all right so hopefully that makes sense
as far as the debate between what soft
clipping and hard clipping is that's all
it is that's all that's explained right
there now with the standard clip you
have these modes you have the soft clip
Pro and you have the classic and the
hard clip and then you have the ratio
2:1 all right I'm only going to talk
about the soft clip and the hard clip if
you turn on hard clip it's again just
truncating the signal right at the top
the Peaks anything that crosses the
threshold it just truncates it and your
threshold is here this is where you're
going to clip so are you going to clip
at zero or are you going to clip at 6db
negative .6 DB let's see this as we play
this music so you can really see what
hard clipping is doing so let's turn
that on and you're going to get a little
visual representation down here in this
window
[Music]
[Music]
[Music]
all right as you can see it's taking the
top of the transients and it's just
truncating them it's chopping it off and
the way you use this clipping this sort
of hard clipping is to give yourself
more Headroom right because you're
taking those Peaks and you're chopping
them off and then you can bring up the
lowlevel information more and you get
that sausage right you get that flat you
know Dynamics kind of get killed and
that's kind of the trade-off with hard
clipping is your Dynamics and your
transients aren't as hard-hitting
because they're getting chopped off so a
lot of people like soft saturation soft
clipping because we're not chopping it
off so much we're kind of rounding it
it's a little bit more musical so let's
check out the soft clipping algorithm
here and I really like the soft clip Pro
on this this is just going to kind of
round that out and I'll AB these all
flip be between them and I'll also take
up this saturation here you can take up
the percentage so check it out
[Music]
so two different algorithms for either
soft clipping or hard clipping and
truncating now let's check out these
other Clippers like gold clip and you
can see what's going on here with the
soft clip and the hard clip and we're
really talking about a knee when we talk
about soft clip versus hard clip if you
have a hard knee once it passes the
threshold it's going to chop the Top If
you have a soft it's going to Round
right so the clipping comes in in a
round fashion and you can see that here
on these little um you know the UI here
see the Clipper if I click on this you
have a hard clip you have a classic
which is in between it's like a hard and
soft right in between and then you have
a hard clip here and you have the modern
which is a softer clip okay and that is
just all it is that's exactly explained
now if you want to clip you just take
this down on the ceiling or you push up
into the clip so if you want it to clip
at .1 cool you can just push more gain
into that Clipper so that you're
clipping the tops if you want to take
this down and not drive the input then
you just find where those Peaks are and
you'll see it in this graph let's check
it out
[Music]
[Music]
all right so there you go hard clipping
versus soft clipping now lastly the
orange clip and this one's actually
pretty it'll show you pretty easily like
visually what a soft clip and a hard
clip is by literally just turning this
knob up so when you turn this all the
way up you're hard clipping right as you
take it down your your soft clipping
right and you can be anywhere in between
you can kind of like round it off a
little bit or you can just clip the tops
right away same thing you got a ceiling
you got an input push that's all it is
it's very very simple hopefully this is
like explaining the clipping idea here
okay this is just clipping the tops the
Peaks the transients whatever
information is hitting the most you have
Peak and you have RMS RMS is like the
overall sound like if you're in a room
and there is a motor going and it's
going
[Music]
the RMS of the room comes up right but
imagine that motor's going and then
every once in a while there's a backfire
of the motor so it's like pop pop right
and every time it pops and I probably
just clip the microphone and that's not
good clipping that's like digital
clipping Distortion and you have no
control over that digital clipping and
that's why it sounds so much harsher so
when you go over zero in your Daw at
24bit or 16bit and you clip that you're
literally going to be adding artifact
and digital Distortion and things that
you can't control so Clippers are a
great way to control that clipping and
make it more Musical and that's why we
use Clippers we use clippers because we
want to get louder records we want to
saturate the tops and the Peaks we want
to chop them off or we want to round
them off with soft clipping and we want
to be able to control that clipping
right with digital clipping if you go
over and you just start pushing your
master fader up when you make that
bounce you're going to hear artifacts
unless you're at 32bit floating point
which gives you a ton more dynamic range
and you can recover those Peaks which
means if I clipped digitally in 32bit
floating point I can bring that file
back into logic Protools whatever and I
can bring the file gain down and I'd see
the Peaks would come back because you
have 32 bit floating point which is like
dynamic range Insanity right so it can
take digital clipping all right but this
is what how we do it with 24-bit audio
we try to clip with clippers because
it's going to give us control over our
Peaks and when we control the Peaks we
can go louder into the limiter now why
use a Clipper instead of a limiter
because a limiter is going to literally
turn down the Peaks so you can get
pumping artifacts right so a limiter you
cross the threshold the limiter turns it
down it's like volume wise it doesn't
clip the peak it doesn't take care of it
and truncate it or soften it and round
it and add harmonics to it some limiters
do that actually but for the most part
it just turns it down on an attack and
release setting right and a lot of
limiters have a very immediate attack
and you know some of them have IRC like
intelligent release controls where it's
adaptive right but others you could set
the attack and release but that's the
big difference between limiters you can
get a lot of if you're hitting it with
SH like crazy amounts of transients
you're trying to take those Peaks down
by turning them down it's going to be
you're going to get all these artifacts
you're going to get things that
are like the pumping effect hopefully I
explain that well I feel like I'm like
jacked up on caffeine talking about this
but to finish off this video I want to
talk about oversampling now because that
is a huge huge part of clipping audio
now if we're going to use a Clipper and
we start to hard clip something or soft
clip something we introduce harmonics
and Distortion right with hard clipping
you're going to clip off the transient
which is going to give you artifacts no
matter what it does not matter so if we
oversample with oversampling like here
you go you have two times all the way up
to 256 times oversampling if I am
sampling right now at
44.1k it means 441,000 samples per
second in my Daw or 48k or 96k whatever
it is pick it times that by 8 times that
by 16 times that by 10 whatever it is on
the oversampling so now we're taking a
picture with a lot of megapixels if you
have a camera that's taking like let's
say 60 megapixels 64 megapixels versus
12 megapixels we have a lot more data in
64 megapixels when we oversample 44.1 at
10 times now we're getting
441,000 samples per second right so
that's oversampling and then when it
bounces the audio it takes it back down
so when it takes it through the process
it over samples it it gives us all this
information which really helps with the
top end the highend right and I'm
talking about like 20K 16k you know up
at the top top because it's oversampling
so many times that's what you get the
most of is the high frequencies right so
this is a really interesting thing
because if you don't have oversampling
then you could get artifacts you can get
aliasing Distortion and things like that
when you make a bounce because you're
clipping you're adding artifacts to the
signal you know but if you over sample
it then you're going to get all that
Distortion and artifacts and all that
stuff you're getting a lot more
information so the process can smooth
that stuff out make it more musical Etc
so that's what oversampling is for when
it comes to clipping hopefully this
video is explaining what soft clipping
hard clipping oversampling is in these
plugins and it's very very important
that you understand these Concepts when
you're using clippers because you know I
see people just clipping the out of
their music not using oversampling not
making you know this stuff really work
for them they're just trying to get a
really loud record and it turns out to
just you know be sounds like a big turd
so use these processes sparingly know
what you're doing with them and
understand that every single one of
these Clippers has its own character so
for example the orange clip is modeled
after the you know very famous Clipper
obviously it's like FL Studios Clipper
right so it's modeled after that
algorithm so you're going to get
different harmonic with the soft clip
and the hard clip that are introduced
with this plugin compared to standard
clip compared to Gold clip and gold clip
I would say is probably the most
professional out of all of these because
you're getting a bunch of other features
you're getting the gold these curves the
gold curve you're also getting the
clipping right the Clipper you could
turn these things on and off by the way
you can bypass them and you're also
getting this gold knob which is
introducing other compression limiting
harmonic structure stuff and you're
getting Alchemy which is like a high-end
uh limiter so it's it's basically taking
down the highend from like 1 or 2K above
so you can clip into it and then you can
take down the top so it's not clipping
the top as much now you can also go into
the back end of this when you hit these
wheels and you could see that there's
oversampling all built in here with real
time and offline which means you could
leave it on high in real time and then
when you bounce it have it on extra
pristine which is going to oversample by
I don't know 24 you know 100 million it
doesn't matter whatever it is but the
whole idea of oversampling is so that we
can get more information from the audio
and we can avoid when we bounce the
audio avoid
that those little weird alosine
artifacts and Distortion artifacts so
use oversampling when you're bouncing
and you're using hard clipping or soft
clipping but especially hard clipping
now if you got anything from this video
please share it drop some love in the
comments ask any questions you got some
of y'all are going to want to argue and
you know think you really know a lot
more about all this and that's cool too
if you guys some have something to add
to this conversation please drop it in
the comments even if you want to call me
an idiot for explaining this weird I'm
just trying to make this simple right
are you sure a tree you chop off the top
with a chainsaw that's hard clipping
soft clipping we're going to trim the
Hedge we're going to make it round we're
going to make it soft okay that's really
the best way to explain it for me
personally and oversampling is literally
taking more megapixels of something so
that we can get all the details in it
and we can soften out the edges and get
rid of any artifacts this Distortion
aliasing all that stuff that happens
when you clip that's all I got for you I
hope you guys enjoyed the video if you
did show some love all right till next
time peace
