Compression 101 | How to Understand Compressors (Made Simple) - Duration: 5:54.
In this video, I'm going to be showing you the simplest way to understand a mixing technique called compression.
Understanding compression overall is one of the ways to get your sounds sounding professionally and
properly mixed into your tracks and allow you to use any compressors that you see out there from the most basic compressors to multiband compressors.
I'm Wilson from CScales, and today you're going to learn the easiest way to understand compression that makes your music sound louder and clearer.
To Start off,
If you haven't watched my video on how to easily understand mixing, check that out first
because this video is going to use some of the basic concepts from that video.
Simply put, compression is just a more advanced way to control one of the three basic mixing movements, which is volume.
Let's define the differences between what compression literally does to the sound and what it's used for in mixing because this can seem confusing at
first. If you look at the sounds through an EQ,
you'll notice the sounds frequency bands. In some sounds sometimes, there are frequencies that are way bigger than the rest of the other frequencies.
What a compressor literally does is lower the volume of these frequencies.
However, when we use a compressor in music,
we're actually making the overall sound louder because when we decrease the volume of the loudest frequencies,
we have to increase the overall volume to compensate for the lost volume from the compression. In other words
what a compressor does is actually boost the lower volume frequencies to match the higher volume frequencies. For this reason
I like to think of a compressor as a tool to shorten the distance between smaller and bigger frequencies,
Instead of a tool that lowers bigger frequencies. So how do we compress a sound? Even though there are many different types of compressors,
they all fundamentally have the same five features which are the threshold, ratio, attack, release and gain. So, how do they work?
Let's relate this to a bullet.
The bullet is a representation of one of the frequencies in a sound and a decibels are the distance the bullet travels in the air.
Let's say you shoot a bullet up in the air. The highest point that it reaches is the volume without any compression.
The atmosphere is zero decibels, the loudest point possible before the sound starts to distort and shatter into more higher
frequencies and becomes impossible to change back.
So generally we don't want to go past this point in compression and mixing in general unless we want to achieve that sort of effect
in a sound. Starting with the threshold, this sets of points where anything louder than this points will have its volume lowered.
I like to think of this as an extra layer of gravity at the
point you choose to set it. When you shoot a bullet past this point,
gravity will push it down even more,
which will lower the bullets distance. How intense the gravity is comes down to the next feature of the compression
which is ratio. Ratio determines how much volume is reduced when a sound goes past a threshold.
So if we shoot our bullet up into our three to one ratio,
gravity will pull our bullets max height down by 1/3
once it hits our threshold. Now
sometimes the gravity becomes so strong that a bullet can't actually get past our threshold and it seems like it's heinous steel wall.
This is a high ratio compression.
which is more commonly called a limiter, which prevents sound from passing a certain volume.
Attack is how fast the compressor gets activated or how fast gravity comes in as soon as the bullet is shot past the threshold.
While release is how fast the compressor turns off or how fast the gravity turns off after the bullet drops down the threshold.
Finally the gain is simply a volume control on the compressor output, which means it's the volume after the compression has been applied.
This is how you compensate for the volume loss during compression and it's like moving the starting position of the gun and a threshold closer
to the atmosphere at zero decibels.
The compression is the same, but it's louder because it's closer to the zero decibels.
Remember again that this bullet is just one of the frequencies of the sound. The compressor acts on every single frequency
that is in the sound. So you really see a bunch of these bullets being compressed differently depending on their volume.
So how do we apply these compression features?
There's two parts of the sound, the transient or the head which is the part of the sound that allows the sound to cut through
the mix, and the tail which is the part of the sound that gives the body and presence.
Compressionn is all about balancing these two parts of the sound to create clarity in both parts of the sound.
Because of this, compression on a kick is completely different from a vocal because their transients and tails are completely different.
I don't want to get into too much
specifics on how to compress every single type of sound, but here are five general compression tips to get you started.
The first tip is that you want to start with a ratio of around three to one and lower the threshold down until the sound
is lowered to about five to ten decibels before adjusting the gain to compensate.
This is typically a good starting range to play with in compression because allows you a middle point to determine whether you should compress some
more or compress less. The second tip is to adjust the release based off of how fast the sound repeats.
If you have a fast repeating sound like a hi-hat, have shorter releases.
This will keep the important transients clear.
If you have a long drawn out
sound like a bass, have a longer release to give it more fullness and sustain on the tail ends of the sound.
The third tip is that if you want to lower the transients in general, set the thresholds to just above the tail with a ratio
of around three to one a low attack. This will compress the transients while leaving the tails untouched. The fourth tip
Is that if you want to lower the tails in general, you want to set the threshold
below the tail with around a three to one ratio and an attack just beyond the transients.
The longer attack is going to have the transients avoid the compression but still have the tails compressed. And finally number five,
Avoid overcompressing the sound.
Overcompression is when you bring the lower sounding frequencies of the sound too high up to the point where it actually interferes with the
other sounds in the track. Your sound should always have the ability to have a full range in dynamics. Ff there are no breaks in
the sound
chances are you're compressing too much and you need to tone the compression down by starting with lowering the threshold and ratio before moving on
to the attack and release. So now I want to hear from you guys. What compression tips are you going to try first?
Are you going to start by lowering your tails for your sound? Are you going to try avoiding over compression?

Sarcoidosis | Pathology | Immunology | Med Vids made simple - Duration: 10:44.
Hi, hello and welcome back to one of the most must-see YouTube channel
for all the Medical students across the globe ,Med Vids made simple
In this video, we're going to see about sarcoidosis
Let's begin!
Before watching this video,
if you haven't subscribed to my channel
already, please press the subscribe
button and the bell icon nearby to get notified as soon as I upload a new video!
So sarcoidosis it's a disease of unknown etiology
which means the cause of the disease is not exactly known.
And there is multi organ involvement in sarcoidosis.
which means various organs are involved in the patients of sarcoidosis.
So this picture is taken from Wikimedia.
This shows the common involvements in sarcoidosis
the patient can have organ involvement starting from head to toe anywhere and everywhere
for example here you can see in this patient there are brain complications
which is marked in the top
and there are few skin lesions which are marked in the legs
such as a erythema nodosum so there can be symptoms and signs anywhere in the body
the most commonly involved organ in sarcoidosis is lungs
which will lead to development of granulomas
and finally development of nodules so
let's see about individual things one by one and we'll get a clearer area of sarcoidosis.
So sarcoidosis is a systemic granulomatous disease which means
there will be formation of granulomas in
multiple organs in the body. Now what is granuloma? Granuloma is one of a
manifestation of chronic inflammation
This type of granuloma is non-caseating
so there are many diseases in which the formation of granulomas along with caseous necrosis
But in this condition in sarcoidosis the granulomas are non-caseating
which means there'll be granulomas but there won't be caseous necrosis
now this is a microscopic picture of granuloma
as you can see here there are multiple cells over here which looks like epithelium dispersed throughout the slide
they're actually activated macrophages which are known as epithelioid cells
and you can see a big cell with multiple nucleus at about 10 o clock position
that is a multinucleated giant cell
so these are the main features of granulomas
so how do the patients present in case of sarcoidosis
most commonly the patients are asymptomatic
they come to be diagnosed with sarcoidosis mostly by a chest x-ray
which has been done for some other cause
and on chest x-ray we can find nodular...
presence of nodules on the lungs or we
can see hilar lymphadenopathy so they
can also present with respiratory symptoms because of lung involvement
and erythema nodosum and arthralgia which are skin and joint involvements
are common in many patients
ocular symptoms such as uveitis which
can lead to pain, blurring of vision and
all that can occur in these patients
skin involvement is also common.
Superficial lymphadenopathy which means enlargement of the lymph nodes around the neck is also common
and there can also be other some other symptoms or other signs
such as elevated calcium levels in the blood which is called as hypercalcemia
and there can be hepatomegaly which is enlargement of the liver
and splenomegaly which is enlargement of the spleen
So now let us see the pathogenesis of sarcoidosis
Pathogenesis of sarcoidosis is not clearly known as I told you earlier
it is a disease of unknown etiology but it has been thought that there is the cause of sarcoidosis
is due to immune dysregulation in few genetically predisposed individuals
so in few people who are genetically predisposed
there is some sort of immune dysregulation
which will lead to increased CD4 positive T helper cell activity
okay so this activity of the CD4 positive T helper cells increases and they start to produce
lot of cytokines such as IL-2, interferon gamma, interleukin 8, tumor necrosis factor etc.,
all these are pro-inflammatory
and they increase the inflammation leading to the development of granulomas
so what happens is there will be multiple granulomas formation over
organs such as lungs liver spleen etc
and all these granules coalesce together to form consolidation and the consolidation
enlarges to form nodules which are about one to two centimeter in size and they are palpable
so the nodules are most commonly seen in lungs liver and spleen of patients of sarcoidosis
The most common finding in about 90% of the cases of sarcoidosis is bilateral hilar lymphadenopathy
which means lymphadenopathy or disease or enlargement of the lymph nodes which
are present around the lungs so this is the most common finding in about 90% of the patients of sarcoidosis
so this is the gross appearance or gross picture of bilateral hilar lymphadenopathy
As you can see here the hilar lymph nodes are so much enlarged in this picture
This is one of the most common finding in sarcoidosis.
So the nodules as I told you earlier is
formed by consolidation of various granulomas
The granulomas which are present at nearby sites join together or coalesce together to form
a consolidation and that will join together to form nodules
The nodules are most commonly seen in lungs, spleen and liver.
As a result of that slowly the liver begins to enlarge in size leading to development of hepatomegaly
the spleen also enlarge in size which is also known as splenomegaly
Skin lesions are very common, say, very very common in the patients of sarcoidosis
Various types of lesions can occur in the skin of these patients
they can be erythematous plaques which are red lesions present on the skin or they can
be various other types of skin lesions in these patients
which can be one of the factor which brings the patient to the doctor
the most common skin lesion which is found as a patients of sarcoidosis is erythema nodosum
Erythema nodosum is actually not a disease of
skin per se, not the upper layers of the skin
It is the inflammation of the subcutaneous tissue which is present under the skin
which should lead to a presentation of somewhat like this
you can see red lesions on the skin
if you palpate them, you can actually feel the raised surface around normal skin surface
This is the common presentation of sarcoidosis
Eye involvement is also very common in these patients
The most common association of sarcoidosis in relation to eye is
something known as uveitis which is
inflammation of the uvea which is the vascular coat present inside the eye
The uvea includes three divisions such as
Iris, ciliary body and choroid. All this
individually or together can be inflamed
leading to conditions such as iritis, iridocyclitis, etc.,
On long-standing cases there can be corneal opacity
glaucoma and all these worsens to develop total vision loss
Vision of the patient can be affected so severely
Lacrimation is also suppressed in these patients because
we all know that lacrimation is production of tears from the lacrimal gland
so what can happen is sarcoidosis can affect lacrimal glands also
there can be granuloma formation in sarcoidosis
which can affect its function so tears production can be affected
This can lead to decreased lacrimation in these patients
Musculoskeletal system is also involved in few patients.
There can be muscle weakness, tenderness and fatigue of the muscles.
This can be brought out in patients.. in few patients of sarcoidosis
In most of the cases, this is not the presenting complaint in most of the patients
if you're gonna see they're gonna present with respiratory symptoms, skin lesions or eye problems
but this is not one of the major complaint. You need to ask history regarding this to bring this out to light
Okay? So this is accompanied by arthralgia which is pain of the joints
It can involve bones also.
Most commonly involved bones are the bones which are present in the phalanges
the phalanges of hands and the phalanges of feet
Now let's see about the treatment of sarcoidosis.
In mild cases if there is acute attack of say erythema nodosum or some other complications
we can treat that with NSAID's and low dose corticosteroids
okay.. So, if there are increased respiratory symptoms such as
which can be due to increased involvement of the lung. We can increase the dose of corticosteroids
Increasing the dose of corticosteroids can help in those cases
but in severe cases you need to treat the patients severely with
drugs such as methotrexate, azathioprine which are immunosuppressants actually
they are anti-cancer drugs okay so these
drugs are associated with increased side effects or let's say adverse drug reactions
such as alopecia which is hair loss and so the treatment of
severe cases can itself lead to various other complications

Simple Chord Trick You Can Use for Your Trap Beats - Duration: 8:24.
allô and welcome to busy works beat.com
today we continue the music theory
series right here busy works beats calm
/ music theory I want to show you a
quick core technique for your trap
tracks and RMB trap tracks to make them
sound really unique now the trick is
that they're not even using courts we
are not using cords let me show you what
I'm doing here let me play it first and
I'll explain why it sounds cool
okay so the reason these chord sounds so
unique is because we're not really using
quartz similar to rock music where they
play fifths we're doing the same thing
here and our chord progression so
technically 1/5 isn't a chord because
you're only playing two notes so if we
break this down the reason it seems like
a chord is because we're playing three
or more notes but technically we're only
playing two notes so if you look here we
have F sharp and we have C what this
really is and we have G sharp as well
now that's a part of our let me zoom in
for you make these notes a lot bigger
hard to see so in the very beginning
okay so it looks like i zoomed into the
wrong portion here's what i was
referring to
so f sharp and then you have C sharp
what this really is is a fourth from C
sharp to F sharp that's considered a
fourth okay just like C the e is a third
see the F is a fourth and we go over
what fourths are busy works beats calm
and our new course called circle of
fifths and circle of fourths secrets
explained we go over not only what a
fifth and a fourth is but the secrets
behind it there's deeper knowledge to it
but the point is we're really just
playing a fourth here and then we're
backing that up with an octave of the
same note
so it's really just a fourth now the
second half right here f-sharp the
c-sharp a little hard to see my screen
is kind of far away so let me scoot in a
little bit more so I can see what is
going on so here we have F sharp and we
have G sharp now G sharp to C sharp is a
fifth so I'm playing the fifth and then
I'm stacking a fourth underneath it so F
sharp and C sharp are fourths together G
sharp and C sharp are fits so I'm
stacking the fourth and then the fifth
and we're doing the octave trick so
we're spacing these out in octave now
here I really like the suspended second
so we're adding a second and we go over
this and a lot of our trap videos how to
do chords for trap especially a busy
works beats calm we have full courses on
chords and chord progressions and one of
the genres recover is trap so for
example we go over in trap music we use
a lot of suspended fourths and a lot of
suspended second chords and this would
be adding the second in so here starting
at G sharp a sharp would make that a
second if we were to build out that
chord so for example the major chord of
G would be G B D so we know the end note
is d so that's our fifth so we're
playing the fifth and then we're playing
a second
so we're stacking a second and a fifth
and then we're just doing an octave of
the fifth it's a lot of fifths a lot of
interval stuff it's not really chords
per se
unless it's in that case the suspended
second same thing here we're playing the
fourth and then the fifth on top and
then we're playing that second so all
we're doing is playing seconds fourths
and fifths and we're just stacking them
up so that's the trick so instead of
thinking like should I play a minor or a
major chord here start thinking in terms
of intervals so if I want to play you
know what's go up an octave C and I want
to play the fifth I'm gonna add G so
it's really two notes playing but it
feels like a chord then to make it
really feel like a chord I can add an
octave of the root note if I want to
make this feel a little more trappy
let's add a second in here add a little
more tension okay and we can do octaves
we can do the fourth
so it gives the same kind of vibe
let's hear it in context okay so another
thing is the vocal part that comes in
let's solo this and then I'll wrap it up
for today
but this eight it supports the chords so
that's why I'm pulling it up pull back
to the beginning first but these are
separate patterns okay so I'm pattern
five where it really gets cool when it
harmonizes again we're using fifths and
seconds and just you know to spend a
second but right here I think I raised
this note up if we pull it back down
it's hard to identify interval stuff
when they're like an octave apart so
what I like to do is pull stuff an
octave up so I can understand what it
actually is so what this actually is is
a fourth and then this little jump here
these two notes
is another force that's forth the fourth
right here and then we can see this jump
is another fourth to jump just an octave
apart I'm stacking this over top the
cords and again it's just fourths and
fifths we're not really making complex
chords
all right so trap music is the modern
rock per se as far as pop music then we
were gonna use the same musical
techniques which is fourths and fifths
just like in rock music so if you want
to learn more about music theory I
highly suggest you join us at busy works
beats dot-com we have tons of courses
there on everything from music theory to
mixing to mastering to composition to
how to make beads to how to sell your
beats how to sell your music it's all
there just go to Bizzy works beats com
every picture you see on the front page
is its own course that's how crazy
in-depth we go we have courses on the
circle of fifths and fourths explained
and all the secrets behind it complex
chords how to build chords from number
or nothing with no scales that's called
chord codes you know so there's a lot
there just go to Bizzy works beats calm

its simple, What Would Jeff Do? Dog Training Tip of the Day #171 - Duration: 1:28.
- Hey, everybody, how are you?
It's Jeff Gellman, Solid K9 Training,
with my What Would Jeff Do? dog training tip of the day.
Tip number 171.
A lot of nonsense going on out there,
always been a lot of nonsense going out there.
People are yelling, people are screaming,
about positive and reward and punishment you don't need.
But let's make it really, really clear,
really, really simple.
Whenever you want to teach a new behavior,
or reinforce a behavior that you want more of,
you use a reward for the dog.
Whenever you want to decrease, eliminate, suppress,
lessen a dog from doing something,
you use punishment.
So you need to learn how to properly reward a dog,
and properly punish a dog,
in order to train what you want,
eliminate what you don't want.
People are gonna yell and scream
that you don't need to use punishment.
Listen.
You might feel that you don't need to do that,
you might feel a certain way.
But guess what?
Facts don't care about your feelings.
Jeff Gelmann, Solid K9 Training,
I'm madly in love with you.
If you're not doing that, if you're not doing a balance,
you're leaving out 50% at a minimum,
of a conversation for your dog, you will struggle,
your dog will struggle,
you are gonna be stuck, your dog will be stuck.
We see it all the time, that's just the way it is.
So, learn how to reward, learn how to properly punish.
Jeff Gelmann, Solid K9 Training, madly in love with you.
Take care, bye.
